An Email on Smartphone

This year, I pulled some favorites from my personal subject line swipe file.

I’ve included 7 subject lines that stood out in my inbox—they’ve got what it takes to compete in the inbox.

I also break down why they worked so well, so you can leverage those same techniques.

You may wonder, why 7?

Well, if there’s one thing we’ve seen again and again in this post over the last 5 years, it’s that oddball numbers are more effective at grabbing a potential email opener’s (or post reader’s) attention.

If you’re new to the post, take a minute to familiarize yourself with the fundamentals of email subject lines.

There are 8 different components we found again and again in our top-performing email subject lines…

8 different components we found again and again in our top-performing email subject lines

1. Self-Interest

These are your bread and butter subject lines—you should be using them most frequently.

They are usually direct and speak to a specific benefit your audience will gain by opening the email.

Self-interest subject lines also help pre-qualify openers by giving them a clue about your email’s body content.

2. Curiosity

If self-interest subject lines work because they communicate a direct benefit of opening the email, curiosity-based ones succeed for the exact opposite reason.

They pique the interest of subscribers without giving away too much information, leading to higher opens.

"They pique the interest of subscribers without giving away too much information, leading to higher opens."

Be careful though because curiosity-based subject lines can get old fast and are the most likely to miss their mark.

3. Offer

Do you like free stuff? Do you like to buy things?

So does your email list.

When you are giving something away or selling something your subscribers would be interested in, directly stating that in your subject line is a great way to convince them to open the email and learn more.

4. Urgency/Scarcity

This is the most powerful type of subject line you have at your disposal.

Subject lines that communicate urgency and scarcity tell readers they must act now.

"This is the most powerful type of subject line you have at your disposal."

Too many of these can lead to list exhaustion so use sparingly and, of course, only when there is truly a deadline, limited quantity, or limited availability.

5. Humanity

Don’t forget to remind your list about the person or people behind your products.

Sometimes you need to thank your subscribers, tell them a story about yourself, or make a human appeal for their attention.

6. News

Keeping your audience informed about new developments in your field builds authority and keeps your open rates high.

These subject lines often work well when combined with a curiosity element.

7. Social Proof

A fundamental characteristic of humans is that we look to the behavior of others when making decisions.

You can leverage this in your email subject lines by mentioning individual’s success stories, familiar names, or highlighting how many people are already using a product or service.

8. Story

Telling a story, or at least teasing the beginning of one, in your subject line is a unique way to highlight a benefit and get the open rate you’re looking for.

Ready for the subject lines? As is our tradition, we’ll start with our top 10 best!

(Quick Rules Note: I’ve only included emails that went out to 100,000 or more contacts. By focusing on emails with a large audience, we avoid including subject lines that performed well, not because of their language, but because of the audience that received them. Also, NAME in the subject line means it contained the email recipient’s first name.)

 

4 Lessons Molly Pittman Learned from Running 1,573 Facebook Ad Campaigns

Content: Blog Post
Open Rate:80%
Analysis: We can see those oddball numbers at work here, with 1,573 Facebook ad campaigns standing out prominently in the inbox. This element also demonstrates a level of authority and mastery on the subject. Lessons from someone testing over 300 ad campaigns a year is certainly going to help most marketers up their game. And with just 4 lessons, the wisdom will be distilled enough that anyone can put it to work!

“Frankly my dear, I don’t Instagram.”

Content: Blog Post
Open Rate:80%
Analysis: Historically, ‘cute’ subject lines haven’t graced these subject line Top 10 lists. But DigitalMarketer has been making a concerted effort to push a more conversational tone in its emails, especially those promoting content. This one strikes a good balance between cleverness and hitting a familiar sentiment for marketers who have been around for a while: what am I supposed to do with Instagram?

ICYMI: Want to be a better copywriter? Open this before midnight.

Content: Mastery Course (Copywriting)
Open Rate:82%
Analysis: Subject line elements like ‘ICYMI’ are particularly effective because they play on people’s FOMO: fear of missing out. This one also cleverly layers in a sense of urgency because there is a time limit that the subject line is working against. Recipients can’t file this one away for later. They must jump on the bandwagon now, or risk being left out.

NAME, Will You Marry Me? 💍

Content: Blog Post
Open Rate: 15.89%
Analysis: Proposing on the first date is a bad idea, both literally and in the figurative marketing sense. But could you turn down a marriage proposal from Ryan Deiss? I didn’t think so. This subject line combines a strong curiosity component with very effective use of personalization. Recipients opened this one to see if wedding bells were in their future.

🚫 💡 NAME​ – Stop ideating. Start implementing.

Content: Blog Post
Open Rate:22%
Analysis: This subject line leverages 2 key components. First, self-interest. Marketers all know that we need to spend less time in the clouds and more doing the work—this promises a path to that result. Second, curiosity. While you know you need to implement, and this email contains a way to do so, it’s not clear exactly what form that takes. You have to open this one to learn what this system is that can help you be your best self.

[Best of the Blog] 5 Copywriting Elements to Test on Your Landing Page

Content: Blog Post
Open Rate:86%
Analysis: This is a classic bread-and-butter subject line. It effectively calls out its value with the ‘[Best of the Blog]’ tag, and promises clear value with 5 elements readers should test. One of the reasons this made it to the top of the list is copywriting was a relatively new topic for DigitalMarketer to focus on, and it seems for good reason—we had 2 different subject lines about copywriting in the Top 10 this year!

[EMAIL MARKETERS] $95 today, $995 tomorrow

Content: Mastery Course (Email Marketing)
Open Rate:22%
Analysis: This subject line formula is one that has worked well for DigitalMarketer for the last few years. It leverages scarcity by emphasizing the impending price increase. But it frames this scarcity through the lens of self-interest—you can benefit significantly if you act now. Calling out your audience (here, email marketers) in a subject line is a great way to encourage engagement as well.

[Announcing DigitalMarketer Lab+] Digital Marketing University

Content: DigitalMarketer Lab+
Open Rate:40%
Analysis: Leveraging news elements is a powerful way to add authority to your subject lines. This subject line does so by bringing the word “announcing” into play. Its press release lingo adds gravitas to the product announcement, helping differentiate the subject line and the product. Finally, calling the product a “Digital Marketing University” promises a new take on familiar concepts.

[In Case You Missed It] Our best-performing blog post of all time

Content: Blog Post
Open Rate:46%
Analysis: Once again, the ICYMI language drives massive engagement because people do not want to miss out. And this subject line is even more effective than usual because it promises the best DigitalMarketer has to offer (which, incidentally, is promoting this blog post)—no small feat for a site with hundreds of articles. By touting the post’s popularity, the subject line appeals to human’s psychological groupthink. If everyone else is looking at this post, I probably should too!

[NAME’s Last Reminder] Up to 90% off our best-selling products gone in 3…2…1…

Content: Product Catalog Flash Sale
Open Rate:19%
Analysis: This year’s top subject line was a bit of a dark horse – oftentimes subject lines using urgency and scarcity sacrifice open rate in exchange for higher conversion rates. But this year we are reminded of a fundamental truth of email marketing: offer scarcity works. This subject line is particularly effective because a 90% discount is extremely substantial. If you’ve been interested in products in the past but afraid to act, getting 90% off will put them within reach.

While those might be the stars of the show, we aren’t done yet. Here are 91 more subject lines and the elements that helped these win in the inbox:

7 Top-Notch Subject Lines Pulled from the Vault (My Swipe File)

Now that we’ve looked at our best email subject lines of 2018, it’s time to look at the subject lines I’ve swiped from other companies. The senders on this list include businesses working in marketing, financial SaaS products, thought leadership, membership products, and ecommerce. Let’s get started, and work our way to number 1.

(Last Minute) This Ugly Email Funnel Generated $300k

Sender: Market Hero
Analysis: This one feels like a lot of marketing emails I get—there’s a dollar amount and a marketing strategy dangled in front of you. These are staples because they work, nothing wrong there. BUT what really stands out to me here is the clever twist on urgency/scarcity. This email creates the same sensation of a “Last Chance” without relying on that somewhat overused turn of phrase. Finding a unique turn of phrase to revitalize one of our core components is subject line dynamite.

You deserve the best (here’s what that looks like)

Sender: LeaderBox
Analysis: This subject line is great because it hooks your attention with a truth you already know. You deserve the best, of course! Hard to argue with. And it really kicks into high gear when it builds on that idea you’ve already accepted, by offering definition to what is likely a very loosely defined concept. All you have to do to get the best is let the email body define it for you. Self-interest plus curiosity nabs the email open once again.

We’re trading wine for answers. You in?

Sender: Winc
Analysis: Something for nothing is always an intriguing offer. But in a world overloaded with marketing messages, we often filter “too good to be true” messaging out. This subject line gets around that by pitching a real exchange. But email recipients know they’re making out like bandits in this deal, and are only too happy to oblige.

Calling all lazy (smart) business owners

Sender: Social Panda
Analysis: I love this subject line! Not because I’m a lazy business owner, but because of the cognitive dissonance it inspires. The idea that lazy = smart is not one our brains are wired to accept, so in order to resolve this tension, recipients need to open up and read the email.

Why YouTube Stars Are More Influential Than Traditional Celebrities

Sender: Think with Google
Analysis: Think with Google often relies on their “Google” clout rather than inbox creativity. But this is a highly effective subject line that reveals a great formula you can use. Take something new and compare it to something familiar to anchor the concept. Here, Google takes YouTube stars, emerging public figures from their platform, and juxtaposes them with something familiar, traditional celebrities on an axis I care about as a marketer—influence. This helps audiences to engage with new concepts that don’t stop the scroll on their own.

RE: details on your future order

Sender: Torrid
Analysis: A friend shared this one with me, but it quickly made its way to the top of my list. The RE: prefix is always eye-catching in the inbox because it usually accompanies emails from people, not brands. But the real winner here is pairing ‘details’ with the phrase “future order.” A bit cocky, sure. But our brains are always monitoring our outstanding dopamine boosts—I mean, purchases. This leverages that unconscious awareness and likely created a few “present orders.”

Official Notice: Your refund is waiting

Sender: TurboTax Online
Analysis: Talk about leading with benefits! Tax season is no one’s favorite time of the year because the focus is always around obligation and the steady approach of April 15th. But TurboTax flips the script, enticing their email list with the shiny golden ticket at the end. The word “Official” also grants a strong sense of authority to the message.

Check Out DigitalMarketer’s 101 Best Email Subject Lines of 2017 (…And a 5-Year Email Subject Line Reflection)

As is our tradition, we’ll start with our top 10 best!

I promise it’s worth it…

Content: Launch a Podcast Execution Plan Flash Sale
Open Rate: 15.41%
Analysis: This is a very blind subject line that basically says, “trust me—click this.” Its success relies completely on the existing relationship between subscriber and sender. Using a line like this only works if there is a certain level of trust, but it certainly paid off here.

 

4 Critical Questions Every Business Must Answer

Content: Free Video Training
Open Rate: 15.64%
Analysis: Specific, odd numbers in subject lines always stand out. And this one combines that eye-catching trick with a powerful piece of value—focusing questions for any and all business owners. This subject line also intentionally speaks to a broad audience, which helped buoy the open rate.

I have good news and bad news…

Content: Intensive Workshop
Open Rate: 15.73%
Analysis: Another great curiosity-based option, this one works so well because it feels honest and conversational. It plays on a familiar idiom and the willingness to admit the contents are not all sunshine (and curiosity about what earned the qualifier “bad”) is a compelling reason to click.

[VIDEO] Social Media + Ecommerce Tech Stack

Content: Blog Post
Open Rate: 16.25%
Analysis: Calling out unique forms of content is a great way to cut through the noise. There are many other examples including [Checklist] and [Poll] that cracked our top 101. This one is also helped by the fact that software and “tech stacks” are a hot button topic for DM subscribers.

🔨 Let’s fix your offer together

Content: Intensive Workshop (Perfect Offer)
Open Rate: 16.66%
Analysis: Getting customized or hands-on assistance is powerful when you know the expert, so this kind of email works well when there’s a “voice” behind your emails. Additionally, the implication that your offer may need some work will resonate with the perfect audience for this offer—it’s a great example of qualifying a prospect with the subject line.

Hiring a content marketer? Use this guide…

Content: Blog Post
Open Rate: 17.09%
Analysis: This is another great qualifying subject line and makes a strong offer. It’s a great example of how effective copywriting is even with just the bare essentials—there’s a clear pain point (hiring) and the answer you need (the guide) squeezed in just seven words. Hemingway, eat your heart out.

⚠️ Your private invitation expires tomorrow night

Content: Intensive Workshop (PSS)
Open Rate: 17.31%
Analysis: This subject line uses second person language (“your”) to really build curiosity about the invitation. Coupling that with the urgency of an impending expiration, you’ve got a recipe for a click. The subject line feels personal, exclusive, and urgent all at once.

Sales ⬆, Refunds ⬇, Retention ⬆

Content: Blog Post
Open Rate: 17.47%
Analysis: Leveraging emojis and symbols in your subject line always gives you a bump in open rates and this one triples down on them. The pattern and repetition are very eye-catching in the inbox and clearly communicate value without needing to give a hint to the topic.

Google Display Network (Your one page cheat sheet)

Content: Blog Post
Open Rate: 18.77%
Analysis: There’s a clear offer here – the one-page cheat sheet – and a more indirect one as well: the simplification of a very complex and powerful traffic platform. This subject line makes a daunting topic feel digestible, and the promise of finding more traffic is always a winning hook.

T&C 2017 in Bora Bora?

Content: T&C Livestream
Open Rate: 19.51%
Analysis: A classic DigitalMarketer headline if there ever was one. This combines elements of curiosity and self-interest with an attention-getting destination that’s sure to pique curiosity. The pattern interrupt of a relocated T&C always jumps out and the natural repetition in Bora Bora’s name does the open rate a favor as well.

Not enough subject lines for you?

Content: Invisible Selling Machine

I called. You didn’t answer.

Content: Blog Post
Open Rate: 15.05%
Analysis: Just reading this subject line makes me feel a little guilty! While it doesn’t take something away, it creates a sense of urgency similar to an expiring offer. And of course, using “I” in a subject line is a great way to humanize email copy.

Content: Blog Post
Open Rate: 15.44%
Analysis: What’s your reaction when someone lets you in on a secret? For most people, it’s to lean in a bit and give them your ear. This subject line takes a traditional (but great) blog post and gives it a bit of mystique.

5 Free Tools You Can Use to Amplify Your Email Marketing

And now that we’ve looked at our best email subject lines of 2016, I want to hand you a several free resources you can use to improve email open rates, click-through rates, and even deliverability rates!

1. A/B Significance Tester

Split testing is one of the best ways to figure out not just what works in email marketing, but what works for your audience. You could read a dozen articles on email tips and tricks but at the end of the day, what you need to know is what the subscribers who have opted in for your materials are interested in.

Unfortunately, when dealing with split testing large audiences, it’s sometimes hard to get a sense of what actually worked. That’s why it’s so important to see if your results are statistically significant—basically, how likely is it that if you ran the test again, you’d get the same results.

I’ve used this free resource from Kissmetrics for more than two years because it’s simple, free, and easy to use to get a read of whether or not your split test results matter.

2. Bulletproof Email Buttons

Responsive buttons are a great way to make the CTAs in your email copy stand out.

In fact, in last year’s subject line roundup, I talked about how DigitalMarketer saw some amazing results from buttons in emails—a 38% higher earning per click for emails with buttons.

But if you aren’t a coder, you’ll need some other resource to help simplify creating these—otherwise, you run the risk of screwing up your email templates or breaking your links.

Luckily, Campaign Monitor has an awesome free solution for creating buttons of all shapes, sizes, and colors. With this tool, creating a button is easy and doesn’t require any special knowledge of CSS or HTML.

A pro tip for slightly more advanced users: you can easily increase the font size as well by changing the value for “font-size” from 13 pixels to whatever your heart (or email template) desires.

3. GifRocket

This one’s for Mac users only, but boy is it a doozy. If you’ve ever seen an email with a “video” in it, most likely it was actually an email leveraging GIFs. GIFs are graphics that store and show a series of images, creating an experience similar to a short video.

For most people, making GIFs requires finding a graphic artist or hiring out the task on Fiverr or TaskRabbit, a slow and often painful process.

But with GifRocket, anyone with a Mac and a video can create their very own GIFs. Here’s an example (which took under 2 minutes to film and gif-ify):

GIF John made using GiftRocket

Combining this software with your smartphone camera can create some magical moments, no technical skill required. All you need is a dash of imagination!

4. Headline Analyzer

If you just can’t quite decide if a subject line you wrote is good enough, maybe you need to test it out “in the lab.”

CoSchedule created a free tool that helps you evaluate the efficacy of your headlines. All you need to do is post your headline in their analyzer and they will give you a score for how well you did, and how likely the headline is to get your audience clicking.

The program identifies what kinds of words are used and how effective they are at evoking an emotional response, or how eye-catching and “powerful” they are.

Feel free to take their advice with a grain of salt—I tend to find them overly critical of short subject lines which have been shown to work well. But it’s a great resource if you’re looking for a second opinion.

5. Sender Score

This one’s a bit technical but is a must-use resource for anyone wanting to make the most of their email marketing.

Do you feel like your emails don’t make it to the inbox as often as they should?

The IP you use to send emails may have a bad reputation, literally.

With Sender Score, you can see the sender reputation that your emails have, and figure out what mailbox providers like Google think of your mails. This free tool from ReturnPath is a great way to keep an eye on the more technical elements of your email marketing. After all, with

After all, with poor delivery, even the best subject line isn’t going to get many opens. So go sign up for a free account and remember to keep an eye on your score.

Don’t stop there!
Read on to Learn DigitalMarketer’s 101 Best Email Subject Lines of 2015 (…And Our 3 Best Email Split Tests!)

First, here are our ten best emails subject lines of 2015…

10. Seriously, get this book.

Content: The Choose Yourself Guide to Wealth (James Altucher’s book)
Open Rate: 16.91%
Analysis: This subject line is pretty direct—seriously means no fooling around. But the blind reference to an as-yet unidentified book demands the recipient take a look inside and see if it’s a good fit for their library shelf.

9. I’m pulling the plug…

Content: Blog Post
Open: 17.13%
Analysis: This subject line uses negative language to great effect. What does “pulling the plug” mean for DigitalMarketer subscribers? Is this bad news (or as it turned out, great news)? Only by clicking through can you find out.

8. 7 split testing mistakes

Content: Blog Post
Open: 17.34%
Analysis: Do you like making mistakes? Neither do we (though it happens). So when someone promises to show you pitfalls to avoid before it’s too late, no one wants to miss the opportunity to do so.

7. How HostGator does retargeting

Content: Blog Post
Open: 17.40%
Analysis: This subject is simple and to the point, with a clear value proposition (learn how to leverage their retargeting strategy). The social proof of leveraging a well-known brand helps validate the information contained within the email.

6. TRAFFIC (on a “shoestring” budget)

Content: Blog Post
Open: 17.79%
Analysis: All caps can be pretty polarizing—no one likes to be yelled at digitally. But when you pick a word business owners love, the results are more positive. And offering a cost-friendly solution to a problem never hurts.

5. 11 sneaky email tricks

Content: Blog Post
Open: 17.83%
Analysis: This subject line uses a number that stands out (11) and a compelling adjective (sneaky) to hook the audience. And everyone loves simple to implement strategies, as implied by words like “trick,” “hack,” or “shortcut.”

4. Facebook Ads (Your first 3 steps)

Content: Perpetual Traffic Episode
Open: 17.87%
Analysis: If you’ve wanted to try something new, like Facebook ads, one of the biggest barriers to entry is not knowing where to start. This subject is clear, direct, and helps people who aren’t sure if they’ll be able to use the information.

3. The YouTube Gold Mine

Content: Blog Post
Open: 17.90%
Analysis: Have you ever discovered a gold mine? Probably not, but it sure would be nice to do so. This subject line combines a high-value proposition with intriguing but vague details. Open up!

2. Thank You!

Content: $1 Trial Offer
Open: 17.99%
Analysis: This is a subject line that works so well we sneak it into our mails every year and it never fails to disappoint. People love recognition, and acknowledgment of what they’ve done (if you swipe just one subject line, make it this one).

1. 23 bizarre products selling online

Content: Blog Post
Open: 18.71%
Analysis: This was one of our experiments for 2015, seeing how some lighter, less actionable content would fare, and the fact that subject line took our top slot shows that this strategy works. This subject promises a fun twist on studying just how crazy ecommerce can be. And lists with odd numbers always catch the eye.

Those may be the cream of the crop, but with 134 million emails out the door, we saw a few other good ones, too.

Should You Test That?

Now that you have our best subject lines of the year, you should be ready to up your own game and start sending some emails.

We’re going to give you just a little bit more information to help you get an extra bump…

Here are our three top performing email split tests of 2015.

1. Highlighting a Pain in the Subject Line

Open rate can lie about performance.

That doesn’t mean that you shouldn’t look at the metric because you definitely should. It’s one of your top four email metrics to watch, along with click-through rate, unsubscribe rate, and earnings per click (EPC).

But here’s a great split test that shows why you can judge a campaign by a single metric.

We ran this subject line split test in March of this year. These were the two subject lines.

The two email subject lines we split tested

The “Little _______ = big sales [QUIZ]” beat out the other one, but the results weren’t significant. So at first glance, the test was a wash. However, on closer examination, the subject line “This is why your prospects aren’t buying” actually had more clicks.

A LOT more.

We saw a statistically significant lift of 18% in click-throughs for the second subject line. The reason? The other headline pre-qualified openers by highlighting a pain they were feeling in their business.

That’s one of the risks with curiosity headlines—they drive more opens but people don’t know what they are getting into when they open. So for more complex or expensive offers, direct and pain-based subject lines can produce better results. Don’t overdo it on the doom and gloom though; a little bit of negativity goes a long way and too much can turn subscribers off your emails.

2. Use CSS Buttons in Your Email

Setting yourself up for mobile wins has never been more important, as more and more people are using their mobile devices to read email, browse the web and make purchases.

Because of this trend, we decided to experiment with CSS buttons during our Black Friday promotion. We tested emails using buttons for the CTA against emails using just text hyperlinks, which had been our standard practice.

Here’s a glance at what each one looked like:

DigitalMarketer email with a CTA button within the body

DigitalMarketer email WITHOUT a CTA button within the body

We figured the button would win, but we had no idea how incredible the results would be. The email with buttons had a 22% higher click through rate, no small feat and definitely a sign that this test was a winner.

But that’s not the mind-blowing part of the results.

We also compared the performance and found that the earnings per click, the amount of money we made for every person who clicked through the email, was 38% higher for the email with CSS buttons.

3. Use Unicode Symbols to Highlight Emails

We’ve said it before, but we’ll say it again–using Unicode symbols in your subject line is a great way to generate a bump in opens.

These symbols are the little pictures that show up in your inbox, including ☼, ★, ☂, and ①. Since Unicode symbols are coded in computer systems like alphabet characters and numbers, they can be displayed on multiple browsers and devices.

Across all kinds of topics and subject lines, we’ve found that Unicode symbols produce a consistent 8% bump in email opens. So these can be a great way to squeeze everything you can out of a big promotion or help push visitors to a particularly strong blog post.

5. A Native Ad in 60 Minutes or Less

Product: Blog Post
Product Type: Lead Magnet
Open Rate: 9.78%

3. Check out my new “man cave” [PICS]

Product: eCommerce EP
Product Type: Execution Plan
Open Rate: 10.24%
Analysis: This is a fun blend of curiosity and humanity—it directly addresses some value Ryan got, a sweet new “man cave,” in the subject. Not only does this spark interest, but it reminds readers about the human connection that brought them to DM in the first place.

2. [URGENT] You’ve got ONE DAY to watch this…

Product: AuthorityROI
Product Type: Course/Information Product
Open Rate: 10.79%
Analysis: Once again, curiosity and urgency team up to create a compelling subject line. If you are careful about using these sparingly, you’ll find that they just work.

But Don’t Do This…

We’re also sharing our top 10 worst emails of 2014 and picking them apart to find why exactly they didn’t work.

Our Top 10 Worst Emails

For these, we looked at emails with the highest unsubscribe to open ratio. Not only did these miss the mark, they drove our audience away! We’re going to work backward, starting with the 10th most unpopular email.

10. [85% Discount GONE] Blog launch “checklist on steroids” price increasing…

Promotion: Blog Launch EP
Promotion Type: Execution Plan
Unsubscribes / Opens: 1.78%
Analysis: This subject line is trying to do too much at once. The framing of the price increase is presented as both a disappearing discount and a price increase. While these mean the same thing, it can be a little confusing and makes the subject line too long. Sticking with short, sweet, and clear is best.

9. Last chance to be a whale…

Promotion: The Whale Method
Promotion Type: Course/Information Product
Unsubscribes / Opens: 1.90%
Analysis: This curiosity subject line is cute, but it’s a little too cute. We’ve found that trying to be too clever or funny with subject lines often hurts an email’s performance. This varies by industry, but for educational authorities, it tends to hurt performance.

8. 321% higher conversions using THIS…

Promotion: Video Sales Letter Formula
Promotion Type: Course/Information Product
Unsubscribes / Opens: 1.93%
Analysis: This subject line isn’t terrible – it combines curiosity with self-interest and makes an exciting promise. So I looked at the body as well. A key issue was that the body was even more blind than the subject line – the promise got lost in the open.

7. uh oh

Promotion: Napkin Project
Promotion Type: Course/Information Product
Unsubscribes / Opens: 2.01%
Analysis: This is a great example of a curiosity subject line that completely misses the mark. It’s too vague and sets a negative tone. Be very careful when using curiosity subject lines, especially when you don’t mix them with other elements.

6. 3-Part Followup Series [Download]

Promotion: Native Ads Academy
Promotion Type: Course/Information Product
Unsubscribes / Opens: 2.09%
Analysis: One of the big issues with this email was that it didn’t explain exactly what kind of follow-up series was being offered. By not giving the audience enough information, those who opened it and weren’t interested in an email follow-up series were turned off.

5. Free traffic SUCKS!

Promotion: Whale Method
Promotion Type: Course/Information Product
Unsubscribes / Opens: 2.21%
Analysis: This subject line strikes a negative tone right off the bat. While that can be very effective way to get opens, it also sets audience members up to feel frustrated. When you go negative, it’s important to really focus on putting a positive spin in the email body.

4. 43% discount GONE at midnight…

Promotion: Video Sales Letter Formula
Promotion Type: Course/Information Product
Unsubscribes / Opens: 2.46%
Analysis: This subject line isn’t particularly bad on its own—it combines curiosity and urgency, which is often very effective. However, the subject line is nearly identical to the one sent the day before. Using the same elements in a subject line two days in a row can make your emails seem stale and leave your audience bored. And bored audiences become unengaged very quickly.

3. This sucks, you lose…

Promotion: Whale Method
Promotion Type: Course/Information Product
Unsubscribes / Opens: 2.67%
Analysis: Another example of a negative curiosity-based subject line. It has a similar issue to the other one—it didn’t spin the tone of the communication enough and left readers with a bad taste in their mouth, leading to a high unsubscribe rate.

2. [GONE TONIGHT] Native Ads training OVER at MIDNIGHT

Promotion: Native Ads Academy
Promotion Type: Course/Information Product
Unsubscribes / Opens: 2.94%
Analysis: This subject line is a little too urgent—overdoing capitalization in the subject line can feel like shouting. And no one wants their email inbox to yell at them. Capitalization is a great way to draw attention but works best in small doses.

1. C’mon – everybody’s waiting for you…

Promotion: Native Ads Academy
Promotion Type: Course/Information
Unsubscribes / Opens: 3.05%
Analysis: This email actually had one of our top 100 email subject lines, but it’s a great example of the double-edged sword of curiosity hooks. The email went to audience members not already planning to attend a webinar. This subject line puts some pressure on the reader which, for those clearly not interested in the webinar, is an, unfortunately, effective way to drive them off your email list.

Still here? Great!
We’re Sharing Our 101 Best Email Subject Lines of 2013 Below!

In 2013, our best email subject lines were all made up of one of the eight all-important elements we outlined at the top of this post…

Perhaps more importantly—NONE of our best email subject lines were:

Cute
Clever

OK… almost none of our best are cute or clever. Every once in a great while a cute or clever subject line will work… most of the time they will get low open rates.

7.  Kindle bestseller in 4 days?

Product: Facebook Ad Power
Product Type: Course/Information Product
Open Rate: 7.8%
