What We’ve Learned from 365 Days of High-Performing Email Subject Lines

Your choice of subject line can make or break your email. It’s the first thing your reader sees, whether it’s the first message you’ve sent them or the one-hundred-and-first.

To see what’s working (or not working!) for our clients, we’ve been going into GatorMail and finding the top 5 subject lines by Click-Through Rate every day for a year. We’ve looked at things like length, emoji use and personalisation to get a sense of what works and what doesn’t.
