Templates and form letter Creation

Happy New Year everyone!

Would love to see what have people seen most success in their campaign template creations design wise.
Are they any html experts that actually just build the code out? I can’t imagine how fun that is or is everyone just loading their elements and designing their layouts into mailchimp and then copying over their HTML into the template section?
Are people using Canva and just embedding the “image” into their templates?

Would love to see what is REW’s direction for template creation as most designers use either adobe products or just 3rd party apps like MC and Canva.

looking at the forum, this has been answered in april.
