100+ Amazing Subject Line Examples

They say don’t judge an email by its subject line, but let’s be honest: We’re always keeping an eye out for the best of the best. After all, the subject line is the first impression your message has on its recipients and can help you improve your opens and clicks.

That’s a lot of pressure for a seemingly short line of text.

So you may be wondering, what to put in the subject line of an email? While there is no secret to the perfect subject line, there are a few words and phrases that can help get more eyes on your emails.

Create a sense of urgency

Getting people to take action from your email can be difficult. There’s a lot that goes into getting more opens and clicks. Creating a sense of urgency is one of those things that can have a big impact on whether or not your email gets read.

Here are some examples to get you started:

1. Back in stock, so don’t miss out

2. This is your *last chance* to shop our sale

3. Tick, tock! 30% off sale ends soon!

4. Going once, going twice…

5. Members get first dibs.

6. We couldn’t wait ‘til Friday!

7. When it’s gone, it’s gone.

8. You might want to hurry

9. A little (limited-time-only) present

10. Available for 24 hours only

11. Last chance to save big: Don’t miss out!

12. Only a few hours left to claim your discount”

13. Hurry, before this deal disappears!”

14. Tick tock! Time is running out for this offer

Have a strong action word

When it comes down to getting your emails opened, experiential verbs (like “celebrate” and “love”) perform better than functional verbs (like “spend” and “grab”). That’s not to say these words won’t work – it’s really all about context.

The thing that everyone can agree on is that if you don’t ask, subscribers won’t take action. So try throwing some of these high-performing words in your next subject line:

15. Celebrate with savings!

16. Act now for friends and family savings!

17. 3 DIY Frame Hacks You Need to Try Now

18. Trust me, you need this

19. Send some. get some.

20. Don’t Let These Get Away

21. Join now and gain access to our premium content

22. Unlock your potential with our exclusive guide

Get personal

Personalization. When it’s done right, it’s awesome! But when it’s done wrong? It can be borderline creepy. 

Not all personalization needs to include your customer’s name. The most impactful personalized subject lines are those that contain information based on past behaviors like webinars they’ve attended or purchases they’ve made.

Here are a few examples of how to do it the right way:

23. Join me for a marg, Olivia?

24. Special delivery for Olivia

25. The jeans you don’t have (yet)

26. It’s time for your next visit

27. Congratulations Jill! You’ve earned a special reward.

28. Keep your Hyundai Sonata running like new for the next 100k miles

This is personalized specifically to a Sonata owner.

29. Get 10% off your next purchase of Levi jeans

This is personalized because this person previously purchased Levi jeans.

30. We’re celebrating you: Get your birthday treat now

This is personalized based on special dates such as a customer’s birth month.

Repeat yourself

Being redundant pays off, especially when it comes to your subject line. That’s because it keeps you, the sender, top-of-mind. And being top-of-mind helps build trust, which can lead to more sales. It’s a win-win!

Try including your name or your company name in the subject line, à la these brands:

31. New and exclusive to Kaufmann Mercantile

32. The Madewell essentials

33. Did somebody say new Glossier?

34. The Giant Weekly Newsletter

35. New and Exclusive to Sephora

We don’t mean to brag, but…

Just kidding, we totally do. And that’s because adding key superlatives to your subject line can help strengthen your core message and make it more effective.

Just check out these example subject lines to see what I mean:

36. New favorite dress, hands down

37. Here’s a special treat, just for you!

38. This is big, huge, gigantic, amazing, incredible

39. Order something delicious

40. The PERFECT Facebook Ad

41. Best of the blog

42. A little luxury at a great price

Pose a question

A question is a great way to spark some curiosity around your email, but it’s the type of question that matters. Yes or no questions perform better than open-ended questions. And don’t forget about sentiment: Questions with a negative association (like don’t or can’t) are the worst-performers.

43. What do you think?

44. Do you like prizes?

45. Can you keep a secret?

46. How could you top this?

47. Today’s the day! Are you in?

48. Best gift ever?

49. Details, please! Did you like your purchase?

Punctuation and capitalization matter

Punctuation can completely change the tone of your subject line with one simple character. And that can impact how your subscribers respond to your message. Even the lack of punctuation can change the gist of your subject, keeping things casual.

Capitalization also has the same effect. Take notes.

50. MAJOR announcement!

51. Extra 30% off sale styles (!)

52. *permission to brag*

53. It’s giveaway time again


55. we’re melting

56. alert! today only

58. N-E-W

59. Flash. Sale. Alert.
