I think a good feature to have would be an option to automatically wrap lines in the plain text emails, at a certain number of characters.
This is common on email newsletters to wrap at 65 characters because it makes them readable in all email clients, and easier to read overall.
Currently I'm having to do this formatting in an external text editor, and then move it into the follow up system, but each time I make changes sometimes my work wrapping gets messed up.
Thanks!
