Release: Split testing

Split testing has landed at Loops! As always, it's available for all users at no additional charge. Test your onboarding copy, split test languages against different geographies or just test two different subject lines.
You can choose to define a control, also known as a holdout, which will continue on in the loop to give you a baseline to test against. You may add an unlimited amount of variants.
Split testing is available in two clicks inside any Loop in the builder. Check out the docs here.
