Humor is an excellent trigger that helps boost email open rates. A funny or witty email subject line exudes familiarity about your brand propelling the user to click on your email.

However, like most things nowadays, you need to be extra cautious with your funny approach. Humor can be subjective and there’s a high probability that people might miss out on your point which means your email gets buried in the droves of other emails in people’s inboxes.

But if you understand your audience well then a well-placed joke can work wonders to boost your email open rates.

Subject Lines with an element of shock

Email subject lines with a shocking or controversial spark certainly work as far as grabbing your reader’s attention is concerned. This approach requires you to be confident in your understanding of your audience. If your audience is intrigued then the chances of your email being opened soar tenfold.

Shocking Subject Lines Examples

Single-word Subject lines

Single-word email subject lines play with the basics of designs. Your brain inevitably goes to the element that sticks out, that’s designing 101- play with uneven patterns to highlight your point.

Single-word subject lines do just that. In the melee of long sentences, a one-word email subject line catches your eye. You have won half the battle then and there. The other half rests on what that word is and is it powerful enough to propel your audience to click on your email.

Single-word email Subject lines examples:

  1. Panic
  2. Hurry
  3. Now
  4. Gone
  5. Exclusive
  6. Sorry
  7. Jump
  8. Hot

Email Subject lines with Numbers

The same logic works on subject lines with numbers. Your brain is naturally drawn to digits in the flood of words. So whenever relevant to your content try incorporating digits in your subject lines to increase your open rates.

Subject lines with Numbers Examples:

  5. 11 Mistakes to avoid when clicking nature photographs

Subject Line with a Personal Touch

personalized email subject lines

No, using your user’s name in the subject line won’t suffice. It’s tried and tested and oh yes, boring. I don’t need to point out why boring won’t get your emails opened. So what do we mean by personal touch?

It’s time you heed to location-specific offers and language, or interest targeting. An email meant just for me? I would want to know what it contains, wouldn’t you? Track your user’s actions on your website and curate an email based on their history on your platform and watch your email open rates soar.

To curate highly personalized subject lines, you must know your audience well enough to know what language, style, and offers will be enticing to them.

Personalized email subject lines examples:

  1. Best of Mumbai: Panache salon and more
  2. Don’t miss out: Special offers on black party dresses
  3. Best party spots in Mumbai

Email Subject Line with scarcity tactics

Examples of email subject lines with scarcity tactics

Oh, this one is probably the most used tactic in the email subject line circles. For one simple reason, they are highly effective.

The inherent fear of missing out pushes the user to open the email. As content writers, you must master the art to evoke urgency and scarcity through your copy. Just throw in some scarcity threatening words and you will be surprised how drastically your click rates will change.

Subject lines Examples:

  1. Final hours to save 80%
  2. Last day… Stickers for only $.50
  3. You’ve gotta hurry if you want %40 off
  4. SEO that works closes at 11:55 PM
  5. Last chance to enter the Disco awards
  6. I hate to say no, but today is your last chance
  7. Price increase coming this Saturday
  8. say goodbye to your exclusive 20% offer
  9. Clock’s ticking ⏲ 50% OFF 500+ items
  10. bye, bye, bye 
  11. It’s there and then it’s GONE. POOF. 

Subject Lines that leverage the human brain’s need for closure

This type of email subject line is my absolute favorite. It flirts with our innate need to find closure and frustrates the user into opening your emails.

Diabolical, I know! What’s worse is that it almost always works.

People love a little mystery in their life, even their inbox would do. Giving readers something that intrigues them might cause them to click on your emails.

Mysterious Email Subject lines examples:

  1. “You’re invited!”
  2. “Did you hear?”
  3. “The ultimate revelation of 2021”
  4. “Don’t do THIS to your hair”
  5. “You and me…….. let it be!”

Conclusion

It all comes down to whether your emails are getting opened or not. Because if your emails are not opened that means they are not seen.

We hope the tips we shared will help you come up with a catchy subject line that catches your audience’s attention.
