Nice and looks helpful. It’s crazy when you think about it - email is so prevalent in our lives, yet the scope of innovation last 20 years is that we can react to an emails with emojis.
What I really want is for unauthenticated senders to be reliably blocked. Even Gmail/Gsuite will allow spoofed emails from the same domain, though it may flag them as spam. I get that there are special circumstances where a legitimate sender can't authenticate itself, but that's their problem.
