At the very heart of a great email is a great subject line. They should get the recipient excited, wanting or simply intrigued and enable them to decide whether to open the email or not. (of course your brand name matters too.)

Think of them as little teasers that the movie that is the email is about to unravel.

So, as email marketing experts, we cannot stress the importance of great subject lines enough.

But we get it, coming up with a great subject line every single time you draft an email campaign is a chore, and one that’s not always so giving. Sometimes the inspiration runs low, or we all face the writers’ block every now and then. Plus, with all the restrictions in place with the length, the characters you can or can’t use, and not giving away too much in a subject line, but also not keeping it too generic, the task becomes even harder.

But dear email marketing manager, fear not, we got you. We have drummed up thousands of subject lines working with 60 ecommerce clients, and today we’re sharing some with you! These subject lines are divided on the basis of the kinds of emails, content, and occasion they can go with. By and large, your subject lines should represent and reflect the brand voice and tonality of the email. Make them funny, punny, witty, and add emojis for added fun. You can even play around with the prehader to add more context or complete the subject line.

You can use them as they are, or you can twist and improvise and make them your own. Whatever you do, you should definitely bookmark this blog post because where else will you find a handy glossary of 200+ subjectlines (and counting)! In fact, more than a blog, this will be a living document where we will add subject lines on a regular basis and make sure that we’re also capturing all the trends! (Hey Gen z hashtags, we’re looking at you!)

Just a disclaimer that while we’ve attempted to cover a lot of the “evergreen” subject lines, you should also factor in subject lines that are contextual to the brand or topical in terms of a trending topic for the time.

So let’s get right into these 200+ Great Email Subject Lines That Work!

Subject Lines As Per Different Klaviyo Flows or automated emails

We’ve already covered that flows are the automated system of emails that are triggered based on a certain customer behaviour or a pre-determined criteria.

Welcome Flow

When a customer enters their email into your email-collection pop-up box, and gets the first email immediately into their inbox, that’s a welcome email. This is one of the most important flows and usually sets the precedent for your relationship with the customer. So here are some tried and tested subject lines for the various flows.
