15 Subject Lines that Stole My Heart: How to Use Curiosity, Open Loops and Dramatic Tension in Your Marketing

(This post was originally published in 2015 but was updated in 2023 with even more awesome subject lines that you can swipe!)

“hey u” read the subject line…

I opened up.

It was from this guy Murray Gray who I had met that weekend at Brendon Burchard’s Experts Academy.

The email was bold and charming and it had me hooked…

He had done his research – knew who I was and what I liked and how to talk to me in a way that drew me in.

Here’s a snippet:

i thought i’d google your name and in this half-asleep state i’m looking at your photos of bangkok and brazil and laos and greece, seeing what you’ve seen, and thinking one single thought:  how cool it would be to go traveling together one day — you with your camera, me with mine –once we both get our content businesses up and running and no longer have any good reason to stay rooted to one spot.

sound good?

the only question that remains is ….  where shall we go?

The funny thing is that in those 3 short paragraphs, he foresaw our entire relationship…

We wrote each other for 7 months before we had our first date. It was the same week I launched Live Your Message. 8 months later we were traveling the world together with our cameras…

I thought I’d share the 15 subject lines he used to steal my heart over those 7 months he wrote to me from London to LA…

  1. hey u
  2. on cheesy songs and wanderlust…
  3. eat, pray, launch…
  4. we are what we create…
  5. zen and the art of seeing opportunity everywhere
  6. DVD mania!
  7. the turns and the twists
  8. eeeeeeeeeeeeeeeeee!!!!!!
  9. Is there a Doctor in the house?
  10. objects in the mirror may appear closer than they actually are…
  11. the way of the wind…
  12. my favorites are…
  13. admit 2 to crazyland
  14. always remember to breathe…
  15. voilà

So there you have it, the evolution of my love affair with Murray Gray.

(A word of warning: if you end up in an email exchange with a copywriter, you may end up married… 🙂

Now let me ask you:

  • How did these subject lines make you feel?
  • What is it about them that drew you in?

Read these 15 subject lines again.

Notice that almost every subject line creates curiosity and tension.

As the famous novelist Anton Checkhov wrote, “If you say in the first chapter that there is a rifle hanging on the wall, in the second or third chapter it absolutely must go off. If it’s not going to be fired, it shouldn’t be hanging there.”

Murray creates an open loop in the subject line that he closes in the body of the email. He starts a story in the subject line that he continues in the email.

This is the dramatic principle that creates books you can’t put down, emails you’re compelled to open and products you’re inspired to buy….

Now, imagine writing your marketing emails with story, romance and dramatic tension…

Do you think it would a difference in your open rate?

Your conversions?

You bet it would!

Don’t go just yet! Below you’ll find even more subject line inspiration for your next email campaigns put into 6 handy categories.

The Question Subject Line

Questions make great email subject lines because they get the reader to think about how the subject matter applies to their own life. The best questions will resonate with the reader and their past experiences, while arousing a sense of curiosity to learn more about the subject and whether their experiences are similar to other people’s.

  1. Are you joining us?
  2. What’s your take on this?
  3. Are you a robot?”
  4. Did you see this?
  5. Want to work with me directly?

The ‘How To’ Subject Line

There’s an old saying in copywriting circles that you can’t write a bad headline if it starts with the words ‘How to’.

The ‘How to’ subject line formula works so well because it forces you to describe the content of the email in very clear language.

  1. How to get better marketing results through beautiful design
  2. How to win friends and influence people
  3. How to get 1,000 new email subscribers in 1 day
  4. How to use storytelling in your email marketing
  5. How to grow your business with Facebook Ads

The Scarcity Subject Line

Scarcity is a powerful driver of human behavior. When something is in short supply, our fear of missing out kicks in and we’re compelled to act. Adding a time or availability limitation in your subject line encourages readers to open and act on your email before it’s too late.

  1. Final day to join (product name) until next year
  2. Find out if you should attend TODAY
  3. 2 FREE Books – This Week Only!
  4. Your last chance for 50% off + free shipping
  5. A hands-off lead gen system (last chance to try it!)

The Announcement or Newsy Subject Line

Using words like “Introducing” and “New” in your email subject line gives the reader a feeling that your email contains new, breaking information they haven’t heard yet.

  1. The hottest new book marketing strategy
  2. RELEASED TODAY: JV Success Roadmap
  3. Case Study – $3.2Mil in a New Niche
  4. NEWSFLASH Latest Property Growth Figures Released
  5. Meet your new instructor…

The Number Subject Line

Using numbers in your email subject lines is a great way to set people’s expectations and provide a structure for the content of your email.

Every time we do any kind of A/B testing of our blog post headlines, we find that the version of the headline containing the number outperforms the one that doesn’t. So where possible and where it makes sense, use numbers to make your subject line more specific.

  3. 20X your potential — physically, mentally, spiritually
  4. 5 “newbie proof” list building secrets
  5. 10 amazing insights into dog training

The Surprise Subject Line

Everybody loves a good play on words or a pleasant surprise. In fact, studies on brain activity show that these unexpected occurrences light up the pleasure centers of the brain.

Whether it’s a small chuckle or an unexpected offer that benefits the user, using surprise in your subject line causes the reader to pause while scanning through their inbox and piques their curiosity enough to open the email and learn more. Remember surprise and delight is one of our peak emotional experiences.

  1. Don’t ask the deer how to hunt it, ask the hunter
  2. Size does NOT matter: The REAL secret of a great relationship …
  3. She said I sucked at love. I LOL’d.
  4. You had me at “Hello”…
  5. Bet you can’t stop at one…

Now, over to you! What’s one subject line you’re inspired to write? Let me know in the comments.

    Thank you for sharing! Often marketing and customer relationship building is compared to a romance, and well it should be. If we all thought about our customers in the way that we think of that new romance, how different our businesses would be!
