I never liked writing email templates. They always broke my sense of beauty (the same way their responsiveness breaks in different clients):
1. Monstrous inline CSS
2. Lots of restrictions on which CSS properties you can use
3. Layout issues

It always ended up like this: I would build a site, define all the styles and inheritance, and then spend hours cutting everything down and trying to squeeze it into email template constraints.

Today I found out this problem is gone. Codex handled it perfectly:
1. Analyzed the styles of the entire site
2. Generated a template that closely matches the site's style
3. Preserved responsiveness
4. Took light and dark themes into account

I only had to slightly tweak the footer text color and that was it. A task that used to take an entire evening now takes just a couple of minutes!
