How Do I Create a Broadcast Split Test?
Broadcast Split Tests are a good way to test different versions of a message to see which gets the best response.
We'll randomly sort your subscribers into up to 4 groups so that you can send a slightly modified version of your message to each group.
Typically you would split test differences in your:
- Message subject
- Link / Call to Action location or wording

The goal of Split Testing isn't to send two totally different broadcasts to different subscribers. Use it to learn about how your subscribers react to different elements of your messages so you can more effectively reach them.

Step by Step Instructions
Go to your Broadcasts page, under the Messages tab.
Click the
button. 
Split Test Broadcasts can only be created for lists that have at least 100 active subscribers. If you don't have that many, you're not going to get statistically significant results.
You'll be prompted to designate percentages of your list to receive each part of the split test (you can specify anywhere from 2 to 4 groups, just make sure the total adds up to 100 percent):

This will create that number of broadcast messages for you to edit, and will split up your subscriber list into randomized groups (using the percentages you provided). You'll be returned to your Broadcasts page.
Edit each broadcast in your split test. Once you've done so, queue them and they'll be sent out at the dates/times you specify.

Split Test Broadcasts only work within the list you create them in. So don't use the Send to Multiple Lists feature while split testing.
