75 Open Subject Line Ideas


The subject line is a first impression. Put your best foot forward. Here are 75 subject line ideas that can help improve your open rates.

They say don’t judge an email by its subject line, but let’s face it: we’re always on the lookout for the best of the best. After all, the subject line is the first impression your message makes on the recipients and can help you improve your opens and clicks.

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

While there is no secret to the perfect subject line, there are a few words and phrases that can help you keep a better eye on your email.

Create a sense of urgency in your subject line

Getting people to take action from your email can be difficult. There is a lot to be done to get more opens and clicks. Creating a sense of urgency is one of the things that can have a huge impact on whether or not your email is read.

Here are a few examples to get you started:

1. So back in stock, so do not miss

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

3. Tick, tock! 30% discount on the sale ends soon!

Have a strong call to action

When it comes to opening your emails, verbs of experience (like “celebrate” and “love”) are better than functional verbs (like “spend” and “reach”). That’s not to say these words don’t work – it’s really all about context.

Anyone can agree that subscribers will take no action if you don’t ask. So try to include some of these powerful words in your next subject line:

11. To celebrate with savings!

12th Trade now for savings from friends and family!

14. Trust me you need that

15. Submit some. to get.

Repeat yourself

Redundancy pays off, especially when it comes to your subject line. This is because, as the sender, you are always up to date. Being top-of-mind helps build trust, which can lead to more sales. It’s a win-win situation!

Try to include your name or company name in the subject line like these brands:

23. New and exclusive to Merchant mercantile

24. The Well done the essentials

25. Did anyone say anything new? Shinier?

26. The giant Weekly newsletter

27. New and exclusive to Sephora

We don’t want to brag, but …

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

ask a question

A question is a great way to add curiosity to your email, but it’s the type of question that matters. Yes or no questions are better than open-ended questions. And don’t forget the mood: questions with a negative association (like not or not) are the worst.

35. What Do you think?

36. Do Do you like prices?

37. Can Are you keeping a secret?

38. How Could you top that?

39. Today is the day! are you in?

40. Best gift ever?

41. Details please! Has Do you like your shopping?

Punctuation and capitalization are important

Punctuation can completely change the tone of your subject line with a single character. This can affect how your subscribers will react to your message. Even the lack of punctuation can change the gist of your topic and keep things casual.

Capitalization also has the same effect. Take notes.

42. HEAD Announcement!

43. Extra 30% off sale styles (!)

44. * Permission to brag *
