That is a genius idea.

As MikeMoke is pointing out, I had the same thing in mind:
CNAME or at least a better communication in the email WHO is mailing (my original email) would be great.

also, to have the emails / mesages, etc branded to be in sync with our brand would be helpfull. it also would build more trust, that this email is no spam.

are customisations with own logo, colors, fonts and CNAME just to name a few, on your roadmap?

Another question: as you might have seen on AppSumo, there are automatization competitors like albato, activepieces or boost-space beloved and in use. are you planning to add those in a not so distant future? You mention this in your video, so I am more asking for just some specifics ;)

beside those questions: a very very nice idea. congratulations
