If you tried what I posted and it didn’t work you are most likely doing something incorrect. I understand your frustration; I do most of my work from scratch without a delivery authoring tool as it gives me much more freedom to do whatever I want without bloated wonky code but this one is easily rectified.
You are publishing to check, correct, not just using the built in preview? Also, the machine you are working on has an email client set up, right?
Let me know how it works.
