Email marketing is a powerful way to connect with customers and get sales. But no matter how well your email content is written, it won\u2019t matter if people aren\u2019t opening your emails to start with. That all comes down to your subject line.<\/strong><\/em><\/p>\n\n\n\n

Now, you don\u2019t need to be a creative genius to get your emails opened. But there\u2019s also no magic template that\u2019s guaranteed to make you a millionaire. Start by using these six email subject line formulas as your guideline, then A\/B email test variables to figure out what your list responds to the most (Kartra can automate that for you by the way), and you\u2019ll be on your way to watching your email open-rate soar.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


1. Ask a question<\/strong><\/h2>\n\n\n\n

This is a classic trick many email marketing campaigns utilize, but it has to be used with some strategy.

Sure you can ask a question like \u201cExcited for the holidays?\u201d But that\u2019s unlikely to resonate with most readers. Instead, try to think of questions your audience might legitimately wonder about<\/p>\n\n\n\n

Sure you can ask a question like \u201cExcited for the holidays?\u201d<\/p>\n\n\n\n

But that\u2019s unlikely to resonate with most readers. Instead, try to think of questions your audience might legitimately wonder about<\/p>\n\n\n\n

\u201cShould you skip dessert at Thanksgiving Dinner?\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201cAre you drinking too much coffee in the morning?\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201cWhen is the best time to say I love you?\u201d<\/em><\/strong><\/p>\n\n\n\n

Just make sure this first impression relates to your business and the content inside of your email.<\/p>\n\n\n\n

2. The Shocking Subject Line<\/h2>\n\n\n\n

If you\u2019re 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.<\/p>\n\n\n\n

You notice the Elvis because it\u2019s unexpected and breaks through the clutter (unless you live in Vegas that is). And a good email subject line is similar.<\/p>\n\n\n\n

Now, this could be a shocking statement:<\/p>\n\n\n\n

\u201cInstagram is dead\u201d<\/em><\/strong><\/p>\n\n\n\n

Or just a shocking phrase. Our \u201cDAMMIT DAMMIT DAMMIT\u201d and \u201cSCREW THE WALL\u201d subject lines fit neatly into that category. This is also a great place to play with negatively-phrased subject lines like:<\/p>\n\n\n\n

\u201cDON\u2019T OPEN THIS EMAIL\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201cStop making this HUGE error\u201d<\/em><\/strong><\/p>\n\n\n\n

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 \u201cDAMMIT DAMMIT DAMMIT\u201d subject line.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

3. The How-To Subject Line<\/strong><\/h2>\n\n\n\n

If ever there was a classic formula for digital marketing headlines that work well on both landing pages and emails alike, it\u2019s the How-To formula.<\/p>\n\n\n\n

\u201cHow to make him fall in love\u201d<\/em><\/p>\n\n\n\n

\u201cHow to get 1000 new customers in a week\u201d<\/em><\/p>\n\n\n\n

\u201cHow to double your earnings in under a year\u201d<\/em><\/p>\n\n\n\n

You get the idea. The key to these subject lines is to focus on a benefit, not the work involved. No one wants to think about \u201cHow to write code,\u201d but the benefit they get from writing code: \u201cHow to earn thousands with one skill.\u201d<\/p>\n\n\n\n

To crank this formula up a notch, we suggest adding a without section at the end:<\/p>\n\n\n\n

How to [BENEFIT] without [PAIN]<\/strong><\/p>\n\n\n\n

\u201cHow to lose weight without doing any cardio\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201cHow to prevent aging without the expensive facials\u201d<\/em><\/strong><\/p>\n\n\n\n

4. The Curiosity Gap Subject Line<\/strong><\/h2>\n\n\n\n

The curiosity gap formula plays on peoples\u2019 innate need to know. You tease a bit of information to pique their interest and then hold back, letting the reader know they need to open your email to find out.<\/p>\n\n\n\n

Our subject line \u201cThe single best way to get customers, PERIOD\u201d<\/strong> did just that. It teased that we knew the best way to get customers, but we didn\u2019t say what it was. They needed to read to find out.<\/p>\n\n\n\n

Other examples of this formula could be:<\/p>\n\n\n\n

\u201cWe were amazed at how well THIS worked\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201cWe\u2019ve got a surprise for you!\u201d<\/em><\/strong><\/p>\n\n\n\n

This type of subject line performs especially well when you pair it with your reader\u2019s specific pain points:<\/p>\n\n\n\n

\u201c15 Bizzare Tricks To Sleep Better\u201d<\/em><\/strong><\/p>\n\n\n\n

5. The FOMO Subject Line<\/strong><\/h2>\n\n\n\n

Speaking of pain points, you don\u2019t want to miss out on this solution! If you\u2019re not familiar with the term, FOMO stands for Fear Of Missing Out. It\u2019s an innate psychological drive \u2014 people are afraid that they will miss out on something. And you can tap into that with your subject line.<\/p>\n\n\n\n

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).<\/p>\n\n\n\n

Examples of scarcity email subject lines include:<\/p>\n\n\n\n

\u201cDon\u2019t miss your last chance to save on Black Friday deals\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201cUh-Oh Your trial is expiring\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201c[URGENT] You\u2019ve only got 6 more hours\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201cToday Only: Get 50% off Access to All Webinars \u201d<\/em><\/strong><\/p>\n\n\n\n

Basically, you just want to induce a sense of urgency. You can do that by literally including the word \u201cURGENT,\u201d or other words like \u201cFINAL WARNING,\u201d \u201cIMPORTANT,\u201d etc. This formula also sets you up for an easy follow-up email with reminders.<\/p>\n\n\n\n

6. The Numbered Subject Line<\/strong><\/h2>\n\n\n\n

Numbers break through the clutter and give a concrete feel to things. You\u2019re attracted to titles with numbers \u2014 you clicked the link to this 6 subject line listicle after all.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

This is such an easy thing to do too. Instead of sending \u201cHow To Get More Likes On Instagram\u201d send an email that says \u201c8 Ways To Get More Likes On Instagram.\u201d Other examples of this tactic include:<\/p>\n\n\n\n

\u201cHow to save $290 extra every month\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201c33% of people say NEVER do this\u201d<\/em><\/strong><\/p>\n\n\n\n

\u201c23 Reasons You\u2019re Not Succeeding\u201d<\/em><\/strong><\/p>\n\n\n\n

Some of Our Best Email Subject Line Examples<\/strong><\/h2>\n\n\n\n

Now, if we\u2019re being honest, some of our best subject lines broke some of the classic rules. And others they followed. To show you how you can get creative with these formulas, here are our top 10 performing subject lines from the past year or so:<\/p>\n\n\n\n

    \n
  1. \u26d4\ufe0fDAMMIT DAMMIT DAMMIT<\/em><\/strong><\/li>\n\n\n\n
  2. Don\u2019t make assumptions<\/em><\/strong><\/li>\n\n\n\n
  3. This is ridiculous.<\/em><\/strong><\/li>\n\n\n\n
  4. Behind the scenes (breaking the \u201claw!\u201d)<\/em><\/strong><\/li>\n\n\n\n
  5. SUPER IMPORTANT AND AWESOME (in all caps, even!)<\/em><\/strong><\/li>\n\n\n\n
  6. The single best way to get customers, PERIOD<\/em><\/strong><\/li>\n\n\n\n
  7. that\u2019s how they GET YOU. (and a confession \u2026)<\/em><\/strong><\/li>\n\n\n\n
  8. NAME \u2013 New training for you<\/em><\/strong><\/li>\n\n\n\n
  9. How to bring home the benjamins?<\/em><\/strong><\/li>\n\n\n\n
  10. Screw the wall<\/em><\/strong><\/li>\n<\/ol>\n\n\n\n

    A few things we learned:<\/strong><\/p>\n\n\n\n

    \u2014> We found subject lines that use emojis can break through the clutter, although this is becoming a more common practice so be wary.<\/p>\n\n\n\n

    \u2014> Including a name added a touch of personalization that people couldn\u2019t help but click.<\/p>\n\n\n\n

    \u2014> And using subject lines that were framed negatively (ie: DON\u2019T OPEN, as opposed to OPEN ME), tended to have higher open rates.<\/p>\n\n\n\n

    A\/B Testing Your Email Subject Line<\/strong><\/h2>\n\n\n\n

    Email A\/B testing is the process of sending two different versions of an email to segments of your email list in order to determine which version ultimately will convert the best\u2014you can compare subject lines, preview text, email copy, call-to-action, and more.

    Also referred to as split testing, this marketing strategy can provide valuable data on the email templates that connect best with your unique audience.

    A Few Tips on What NOT to Do<\/strong><\/h2>\n\n\n\n

    1. Don\u2019t Be Spammy<\/strong><\/p>\n\n\n\n

    We are all about using creativity to get a reader\u2019s attention but beware of using clickbait subject lines that convince people to open emails and don\u2019t deliver on what they promise. This practice is likely to land you in the spam folder, rack up unsubscribes, and ultimately affect your deliverability, especially if you\u2019re sending out cold emails. Make sure your subject line clearly relates to the body of the email so there are no unpleasant surprises.<\/p>\n\n\n\n

    2. Don\u2019t Overuse Exclamation Points or All Caps<\/strong><\/p>\n\n\n\n

    Punctuation and capitalization can be effective at attracting attention, but be judicious with emphatic formatting\u2014know what we mean?!??!?! Too much of it can feel spammy to your email recipients \u2013 see point one!<\/p>\n\n\n\n

    3. Don\u2019t Forget to Test Your Subject Lines on Mobile Devices<\/strong>
    <\/p>\n\n\n\n

    What catchy email subject line will you write today?<\/strong><\/h2>\n\n\n\n

    You may have noticed that some of the subject line formulas overlap, and that\u2019s perfectly okay. You can add numbers and scarcity, or how-to and curiosity. Mix and match and figure out what works for you.<\/p>\n\n\n\n

    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 through rate, and goal conversion rate of every sales email and email newsletter you send.<\/p>\n\n\n\n

    And then, maybe this time next year, you\u2019ll be able to tell someone else what YOUR best 10 subject lines from the year were.<\/p>\n\n\n\n
