Hi fellow email geeks.

I was interested to know if anyone has any methods for testing new templates vs old when introducing a new email product suite?

Previously, I've segmented the most active part of our recipient list and A/B tested the old template vs new template for a number of alternative weeks. We add a notification onto the email to let them know why they might receive different templates and also offer a link to a short survey to encourage feedback.

When introducing new templates over an existing suite, does anybody have any tips, hints or methods that they use and are keen to share?

Thanks in advance,
