INSIGHTS Top 16 email subject lines to increase your open rate
Whoever said you should never judge a book by its cover did not consider email marketing!
With mountains of insights from A/B testing and data analysis we know that the right (or wrong) subject line can make or break an email campaign. You may have Nobel-prize winning articles or the best product discounts within the email but what use are they if no one is actually opening it?
So how can you cut through the clutter in a customer’s Inbox and make sure your email gets seen?
A solid email marketing strategy is of course vital before you start hitting the virtual doormat. By the time you’re ready to select your subject line, you should hopefully have already thought about the following:
- Audience - who are you talking to?
- Content - is it relevant to that audience?
- Testing - how does your email actually look and perform on different devices such as Android vs iOS vs Desktop?
Now you’re ready to find that winning subject line! There are also numerous free subject line checkers available online, and many of the top email marketing providers will also offer you the option for A/B testing. Often this means that your provider will ‘learn’ which email is performing best and then prioritise that over the other. Nifty.
But, let’s not leave it all to chance or algorithms. Here are 16 of our tried and tested ‘themes’ that make up many of the most successful email subject lines.
1. Me, me, me
Self-interest should definitely be at the top of your list when it comes to subject line ideas. Knowing your audience and their interests is key here to delivering content that will benefit them by opening the email.

Your marketing sucks
Does your kid know more about technology than you?
By personalisation we don’t mean ‘Hey Bob’. In fact it’s the opposite - these days adding names has become so over-used these emails often get marked as spam instead. No, we mean knowing your audience, what do they love, where do they live? Think about something that shows you know and understand them.

13. Be timely
There’s always a risk element to this type of email - if someone misses it in their Inbox then it may not be so relevant three days later. But get it right and it could send your open rate soaring!

14. Question and answer
This is where you speak to someone’s interests, or even their problems or anxieties. The key though is to always provide an answer or solution within the email. That way you’re enticing them to open, but by offering a resolution you’re also making yourself an invaluable resource too.

15. Short and sweet
We’re all short on time these days, so often single words or short, snappy phrases can stand out better. In fact, research suggests that email subject lines should be no more than 9 words and 60 characters long.
