I've been trying to find this all over and can't figure it out. Can I use Champion/Challenger testing if my email has dynamic content? We routinely do a single email but then use dynamic content to slightly modify the copy based on the country the lead is located in. I want to test using champion/challenger for various items (right now it's CTA button vs CTA text link) but I wasn't sure if it would work with my dynamic content. Any help is appreciated!
