Unlock Better Email Results with These A/B Testing Hacks

Here’s the deal: if you’re not testing your emails, you’re just guessing. And guessing doesn’t cut it when everyone’s fighting for attention in the inbox. That’s where A/B testing comes in—it’s like a cheat code for figuring out what your audience actually wants.

But here’s the catch: not all A/B tests are created equal. Let me break it down with a few tips we’ve picked up along the way:

One Change at a Time

Keep it simple. Test one thing—like your subject line, the call-to-action (CTA), or even the send time. Trying to test everything at once just muddles your results.

Divide and Conquer

Split your list into equal groups and make sure the sample size is big enough to give you clear results. Random selection is key—don’t overthink it.

Know What You’re Looking For

Are you trying to boost opens? Get more clicks? Drive actual sales? Decide upfront what success looks like for your test.

Little Tweaks = Big Wins

Sometimes it’s the smallest changes—like swapping a word in your subject line or moving the CTA button—that make the biggest difference.

Timing is Everything

Ever tested sending an email on a random Tuesday morning versus Friday night? You’d be surprised how much timing can change your results.

Learn from Every Test

Win or lose, every test teaches you something about your audience. What works? What flops? It’s all good intel for your next campaign.

Oh, and don’t stress if a test “fails.” That’s part of the process. Every dud is a step closer to figuring out what really works.

So, what’s the weirdest or most surprising thing you’ve learned from an A/B test? I’d love to hear your stories! Drop them below. ??
