In 2015, DigitalMarketer sent 134 million emails…
…Emails centered around promotions, blog posts, charity, and certifications. And we learned a thing or two about what works in the process.
It’s safe to say for us, 2015 was “the year of the content mail.” DigitalMarketer has become much less reliant on promotional emails as our primary means to engage customers (we still run promotions, but they aren’t as essential for driving traffic).
Instead we have begun to focus more on email as a content distribution platform, to help us segment and excite customers about our products.
What can you take away from that lesson? Make sure you’re incorporating the value-first strategy into your email calendar, and not prioritizing promotions too highly over content. If your customers aren’t getting value, they aren’t opening your emails (and you’re missing tons of sales and relationship-building opportunities).
We went data digging and found our best 101 subject lines for you to swipe or use as inspiration. And as a bonus — we’ve also rounded up our 3 best email split tests you can use to optimize your email marketing in 2016.
This is our third annual Best Email Subject Line Roundup, but there’s 202 more subject lines for you to swipe here:
Before we dive into our 101 winners, let’s look at what common elements you might find in a subject line. There were 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. These peak 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. 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
Sometimes you just need to thank your subscribers or send them a holiday greeting. Don’t forget to remind your list about the person or people behind your products.
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 our tradition, we’ll start with our top 10 best…
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 acknowledgement 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. Here are the next 90 subject lines that had the highest open rates and a breakdown of the elements that compose them:

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 3 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 4 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 “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:
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.
, 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.

- Product: AuthorityROI

- 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.

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 backwards, 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’s 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 followup series was being offered. By not giving the audience enough information, those who opened it and weren’t interested in an email followup 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.
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 8 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.
For the most part it pays to be direct and clear.
Ok… let’s take a look at our top email subject lines.
We begin with the 10th best email subject line…
10. Breaking News…
- Product: Black Friday Webinar
- Product Type: Webinar
- Open Rate: 7.6%
- Analysis: This subject line promises that the reader will find something timely and unknown if they open up.
9. Facebook traffic is dead?
- Product: Facebook Ad Power
- Product Type: Course/Information Product
- Open Rate: 7.6%
- Analysis: This subject line creates plays on a reader’s self interest — particularly those that are using or are considering using Facebook for business.
8. Everybody’s waiting for you…
- Product: Funnel Webinar
- Product Type: Webinar
- Open Rate: 7.7%
- Analysis: This is a clever way to use urgency in an email subject line. This email was sent a couple of minutes after we started the webinar it was promoting.
7. Kindle bestseller in 4 days?
- Product: Facebook Ad Power
- Product Type: Course/Information Product
- Open Rate: 7.8%
- Analysis: This subject line promises a benefit in a short amount of time — a good example of a self-interest subject line.
6. Watch live? From anywhere?
- Product: Traffic & Conversion Summit (Event)
- Product Type: Event
- Open Rate: 8.0%
- Analysis: This subject line creates curiosity. It creates the following question in the reader’s mind: “Watch what from anywhere?”
5. Facebook closing down?
- Product: Facebook Ad Power
