What is a good email template designer?
I need to design some emails, but unfortunately the support of CSS in various popular clients seems to be completely outdated.
Therefor I hope some of you know a program or service that allow me to design the email (WYSIWYG) so I don't have to study the limits and spend too much time on it.
They also need to be responsive in that sense on a mobile they should seem a little different, but that's it about responsive I guess.
