Automatic email campaign optimization.

Remove the guesswork from your email marketing! A/B testing lets you try two different ideas at the same time, splitting the two versions between a sample of contacts and automatically choosing the one that performs the best according to your criteria once the test is finished. Choose how large of a sample you want to send to, how long you want to wait for results before choosing the winning version, and which metric you want to use as your performance: opens or clicks.

Test two ideas on a sample of your audience and automatically send the version that performs the best!

Higher open rates and more conversions for your emails.

It’s tough to know what content you should put in your email to get the most engagement. Luckily, A/B testing eliminates this problem for you by letting you try out two different ideas at the same time and find out which one works best. This helps you get to know your audience better and improve your email campaign performance because you can automatically send the best version of your campaign to your list after seeing the performance with a small sample. You can also follow the results and keep track of insights for future campaigns!
