Have you ever received an email campaign and you thought “Wow, this is really great!” ?

Maybe it had a nice design, maybe a strong story, maybe it was very personal.

Let me ask you another question, before I hop on to giving over a 150 email split test examples.

Did you buy from that lovely mail?

As marketers, we know that a single on the mark email can outperform your average newsletter by a mile.
But it isn’t a beauty contest to see who can make the best-looking email or even the smartest email.

The challenge is to get the most engaging result rich email possible.

You might be thinking, simply said, but Jordie which email will do better than others?
Should I do this version or that version?

The ultimate answer is simple: You come up with one great idea.
and then (this is the trick) a second great idea. The second idea can be a different idea or a variation of idea 1.

Then you let those (and possibly version 3,4,5 and 6), battle it out for the win by running an email split test.

Can you lift all your email campaign results to that top level? That all depends on the quality of your ideas.

Know what works with A/B email split testing

Knowing what works is key to insightful marketing campaigns. With A/B split testing you have a great result booster at your disposal.

A/B testing will help you pinpoint which version of your email campaigns is the most effective.

But marketers often get stuck or run out of fresh ideas for email split testing, making it repetitive. So I often get asked for examples of good email split tests. Econsultancy research suggests that there are only a few email split tests that are often done by marketers… which is a shame seeing there is so much more to explore. A good reason to try the fresh email split testing ideas below!
