A/B Testing is now available

It's been a long time coming, but today I'm excited to announce that our new A/B testing feature we announced a while back is now live and available in all accounts.

We've worked hard to make sending an A/B campaign just as easy as sending a regular one. You can test different subject lines or sender details in a matter of seconds. If you have the time to create a simple design variation for your campaigns, this is also a breeze to test. I really can't think of a good reason to send a regular old campaign any more.

The best part, you learn something from every single test you run.

One of my favorite new features that come with the A/B testing update are benefit estimates. Basically, after the test is run and the winning version is sent to the remainder of your subscribers, we'll look at how much better the winning version performed in your test and extrapolate that across the rest of your campaign results.
