Thank you for coming to the community to give us your feedback.
We can see how having more font styles can be important to tie in your designs when crafting an email. We are constantly trying to add more and more design options..and actually recently added more font styles not too long ago!
However I see we do have a feature request for more font styles, and I will happily add your name to the list of those requesting this feature! if you have any other recommendations please let us know!
