I'm going to give you a niche idea. An email provider / hosting / client focused on a single user owning a whole domain.

I don't care about individual email addresses. What I really want is to be able to handle [e-mail] both for receiving but more importantly for sending.

Receiving is fairly easy with aliases and catch-alls. But for some reason all clients / providers make it really hard to send emails from any address you own.

I think there is money in this problem.

This would be nice. I am using Proton right now, with my own domain. I can make up any address and have it go to my catch-all inbox, which works decently well. However, every so often something will want me to send an email and that's a problem.

I was buying a pair of shoes online and some kind of fraud flag was raised. They asked me to reply to their email to prove I owned it. I ended up replying from my actual account, as I didn't want to burn one of my actual address on a one-time thing. I never gave the email I sent from to anyone, and it has received 0 emails, I really didn't want to risk having it added to their email list by using it, but didn't feel like I had a lot of option. I went on a bit of a rant as a reply, explaining my whole setup, why wha they were asking was problematic, and warning them how irate I would be if the email I was sending from ever got spam in the future, I'd know it was from them.

Of course, the more I try to solve this email problem by using additional addresses, aliases, etc, the more I think I'm just creating a larger problem. If I could go back in time, I would probably not do any of it, and instead just have the 1 address that I use for everything to keep it easy. Instead of investing time in making new accounts, actually invest time in clicking unsubscribe, blocking, and training the spam filters... also, being very selective about where it's used, although that can be difficult these days.

I recently migrated to Fastmail, and they are handling this very well.

Also on fastmail, it's not _perfect_, but it's not as problematic as I've seen elsewhere.

This is part of a feature I'm working on for my service, Port87. Single user domains would work the way labels work in the @port87.com accounts. So all you'd need to do to send from an address like "[e-mail]" is create a label called "myaddress".

I don't have the custom domains feature ready yet, but once I launch it, it sounds like it would fit your needs.

The reason why automated email sending is difficult is intentional as an anti-spam measurement.

I'm not an expert, but I believe that each subdomain needs to improve its own spam score.

Getting to a point where you can automatically send emails from any domain is easy.

Getting it to arrive to any inbox is the expensive part.

In Thunderbird, you click the "From" dropdown, do "Customize From Address" and type the address you want to use. Works for me anyway.

Agree, setting up a new outgoing address is very annoying in Exchange 365
