Reading Time: 4 minutes

Can you imagine if you had to read every single email that landed in your inbox?

Just the thought of it is enough to make you break out in a cold sweat—there’d be no time left for anything else!

It’s the same thing for your recipients. You want them to read your emails, but they’re probably receiving more than they can read as well.

Just like you, they skim through their inboxes and only stop if something grabs their attention. If it doesn’t, it’s ignored or deleted, never to be seen again.

That’s why catchy subject lines are so important. They help you stand out in a busy inbox. Other senders using boring subject lines is your opportunity to shine—and we’re going to help you. In this article, you’ll find 68 examples of the best email subject lines for different types of email, and learn how to make them yourself.

How to write a catchy email subject line

Writing a catchy email subject line can feel difficult at first, but with practice you’ll quickly get the hang of it. Use the following tips to help you find early inspiration:

Be true to brand character

Your subject lines, like all of your messaging, should stay true to your brand character—try to avoid writing something that gets attention but doesn’t sound at all like you. If your brand uses humor or playfulness, experiment with incorporating those elements into your subject lines.

Add personalization

Let your recipients know the email is for them. You can mention their name, reference their birthday, or include their purchase history to make it clear they’ll love this email.

Be specific with benefits

If your subject line gives clear benefits, your recipients are much more likely to take note. Think about what outcomes they can expect, or why this particular email is so important for them to read.

Ask a question

Questions make people start thinking of answers, so they’re incredibly powerful—particularly when you only have a second or two to get someone’s attention in the inbox!

Use humor

If you can make your recipients laugh or smile, they’re more likely to open your email. An example of this would be a food-email using “Hungry for discounts? Here’s a free coupon.” If you choose the humor route, be careful not to rely on it too much and remember to keep it relevant to your brand.

Your subject lines should ultimately convey the value inside your email, so don’t oversell or deviate from what the email is about just to try and get more clicks.
