Multivariate Testing for Emails
We have an email that's going out to our entire database, and we'd love to split test subject line *and* content. That means 4 versions in total.
Subject line A + Content A
Subject line B + Content A
Subject line A + Content B
Subject line B + Content B
What's the easiest way of performing this test? I'm thinking it's probably going to have to be done manually by creating two separate email campaigns and A/B test in both. Is there a better solution?
