Email marketing is a powerful way to connect with customers and get sales.
But, no matter how well your email is written, it won’t matter if people aren’t opening your emails to start with.
That all comes down to your subject line.
We’re going to share with you our top six formulas for email subject lines, but first, we figured we’d share with you our top 10 performing subject lines from the past year or so.
- ⛔️DAMMIT DAMMIT DAMMIT
- Don’t make assumptions
- This is ridiculous.
- Behind the scenes (breaking the “law!”)
- SUPER IMPORTANT AND AWESOME (in all caps, even!)
- The single best way to get customers, PERIOD
- that’s how they GET YOU. (and a confession …)
- NAME – New training for you
- How to bring home the benjamins 💵
- 😡Screw the wall
If we’re being honest, some of our best performing subject lines broke some of the classic rules. And others they followed.
We found emojis broke through the clutter, although this is becoming a more common practice so be wary.
Including a name added a touch of personalization that people couldn’t help but click.
And using subject lines that were framed negatively (ie: DON’T OPEN, as opposed to OPEN ME), tended to perform better.
Now, you don’t need to be a creative genius to get your emails opened. Simply follow these formulas, and A/B split test variables (Kartra can do that automatically for you by the way), and you’ll be on your way to watching your open-rate soar.
1. Ask a question
This is a classic trick many marketers use, but it has to be used with some strategy.
Sure you can ask a question like “Excited for the holidays?”
But that’s unlikely to resonate with most readers. Instead, try to think of questions your audience might legitimately wonder about
“Should you skip dessert at Thanksgiving Dinner?”
“Are you drinking too much coffee in the morning?”
“When is the best time to say I love you?”
“Are you making this big business mistake?”
Just make sure it relates to your business and the content inside of your email.
2. Say Something Shocking
If you’re walking down the street and you see someone decked out in a full-on Sparkly Elvis costume at 9 am, are you going to notice? Probably. What about the guy in the business shirt and tie drinking his coffee? Less likely.
You notice the Elvis because it’s not expected and it breaks through the clutter (unless you live in Vegas that is). And your email subject lines are similar.
Now, this could be a shocking statement:
“Instagram is dead”
Or just a shocking phrase. Our “DAMMIT DAMMIT DAMMIT” and “SCREW THE WALL” subject lines fit neatly into that category. This is also a great place to play with negatively-phrased subject lines like:
“DON’T OPEN THIS EMAIL”
“Stop making this HUGE error”
However, we offer a small word of caution on this subject line style. The things that are likely to get the most attention may also get you a couple of peeved readers as well. Our customer service team definitely got a mouthful from a select few after we sent out our “DAMMIT DAMMIT DAMMIT” subject line.
This is good though because research has found that polarizing branding actually performs better. Sure some people will be upset, but others will be super FOR the risk you took. Much better than being the bland toast brand that no one can remember the name of.
3. Teach Them How-To
If ever there was a classic formula that works well on both landing pages and emails alike, it’s the How-To formula.
“How to make him fall in love”
“How to get 1000 new customers in a week”
“How to double your earnings in under a year”
You get the idea. The key to these subject lines is to focus on the benefit, not the work involved. No one wants to think about “How to write code,” but then benefit they get from writing code: “How to earn thousands with one skill.”
To crank this formula up a notch, we suggest adding a without section at the end:
How to [BENEFIT] without [PAIN]
“How to lose weight without doing any cardio”
“How to prevent aging without the expensive facials”
4. Make them curious
The curiosity gap subject line plays on peoples’ innate need to know. You tease a bit of information and then hold back, letting the reader know they need to open your email to find out.
Our subject line “The single best way to get customers, PERIOD” did just that. It teased that we knew the best way to get customers, but we didn’t say what it was. They needed to read to find out.
Other examples of this formula could be:
“We were amazed at how well THIS worked”
“15 Bizzare Tricks To Sleep Better”
“We’ve got a surprise for you!”
5. Add A Number
Numbers break through the clutter and give a concrete feel to things. You’re attracted to titles with numbers — you clicked the link to this 6 subject line listicle after all.
And studies have backed this up. A few large companies have tested including numbers in their subject lines vs not and every time, they get higher open and response rates by including numbers or stats.
This is such an easy thing to do too. Instead of sending “How To Get More Likes On Instagram” send an email that says “8 Ways To Get More Likes On Instagram.” Other examples of this tactic include:
“How to save $290 extra every month”
“33% of people say NEVER do this”
“23 Reasons You’re Not Succeeding”
6. Give them FOMO
If you’re not familiar with the term, FOMO stands for Fear Of Missing Out. It’s an innate psychological drive — people are afraid that they will miss out on something. And you can tap into that with your subject line.
To do this, you want to create a limited time offer and add scarcity and urgency to your subject line (and if you have Kartra, you can even add a ticking countdown timer inside your email).
Examples of scarcity email subject lines include:
“Don’t miss your last chance to save”
“Uh-Oh Your trial is about to expire”
“[URGENT] You’ve only got 6 more hours”
“Today Only: Get Access For 50% off”
Basically, you just want to induce a sense of urgency. You can do that by literally including the word “URGENT,” or other words like “FINAL WARNING,” “IMPORTANT,” etc.
You may have noticed that some of the subject line formulas overlap, and that’s perfectly okay. You can add numbers and scarcity, or how-to and curiosity. Mix and match and figure out what works for you.
But the real key is to test, test, test, and to look at your analytics. Because, while we wish email was one-size-fits-all, the truth is, every audience is unique. The best way to test is with Kartra. You can set up automatic subject line split tests and Kartra will let you know the clear winner. You can also easily track the open rate, spam rate, click rate and goal rate of every email you send.
And then, maybe this time next year, you’ll be able to tell someone else what YOUR best 10 subject lines from the year were.
