Hey, Our methodology is to test something in sandbox temporarily, but then make production and sandbox environments the same. This way we can ensure that our automated tests (that are running using our sandbox) are checking the same that would happen in production... It is crutial to make sure communication profiles are set up in the same way. Otherwise we can end up in a situation where all our tests are working well but production breaks or vice versa. However, I'm mostly referring to callout settings in this case - email templates are not something we would test with automated tests. Thank you for your consideration. Regards, Benedek
