# A/B test using segments

* [ ] Create a segment called "A/B one"
* [ ] Add some contact lists
* [ ] Scroll to the bottom where it says "select subset" and pick a randomized percentage or count
* [ ] Create a segment called "A/B two"
* [ ] Add some contact lists
* [ ] Scroll to the bottom where it says "select subset" and pick a randomized percentage or count
* [ ] Add a list membership rule in "A/B two" for "not in segment A/B one"
* [ ] Add a list membership rule in "A/B one" for "not in segment A/B two"

You can send anything you want in a different broadcast to each segment, you're not limited to just testing subject lines or message bodies, you can test unlimited variables this way. <br>
