Hello @Upsetfish ,
Transferring emails between accounts either requires that they be under the same Partner setup, which is for things like franchises and affiliated 3rd party businesses, not for testing accounts. There is a paid option for $50 per email transfer that our coding team can do, but for the purpose of testing the software this wouldn't really fit your needs.
In all honesty, the best method would be to simply recreate the template in the testing account. This provides practice for building the template, importing images and other elements needed for it, previews and test sends, as well as scheduling it for a live send (even if just to yourself).
If you'd like some pointers on design or some tips for getting started, I'd recommend following along with this article when you're creating your email. When you have the time, we also have a Getting Started guide (also available in video format). You're also welcome to call our general support so they can work 1:1 with you, and also screenshare while you're logged into your Constant Contact account.
