Hi Craig, thanks a lot for your time and your help! Actually, I already
looked through the documentation you mentioned, before I asked for help
here.Unfortunately, it is not exactly what I need. That would be the way
for users. What I need is documentation for developers who code e-mail
templates and implement them in Adobe Campaign, or also interesting for
me whether there are options for customizing the editor. Whether I, as a
developer, can provide other "content components" for my customers ...
