This is cool but tbh having numbers in the domain makes it feel kinda sketchy especially for a business email, also i already wouldn’t use proton for business due to the worry of getting caught by spam filters so it would be much more difficult to use this, especially since its hard to know if you’ll be able to sustain the business for 5/10/15 years.

Im glad youre working on it though and ill keep an eye out on your progress!

This fucks. Joined your waitlist!

I didn't see in the "about" what jurisdiction (if any) you are incorporated in. I also don't see if there's any encryption at rest.

This is important to me because in the US, the government can go to court, get an order demanding a US email provider to put in a backdoor, and then get a gag order so the US company can't disclose it to users.

And with open-source code, I end up trusting to some extent that the server code matches what is on github, so making it open-source doesn't stop forced backdoors and gag orders if it's based in the US.

For someone whose threat model doesn't include the government (someone not LGBT+, not Latino, not trans, a political moderate with average viewpoints who won't be impacted regardless of who is in power), it's not the sort of thing that matters. But for others, it would help to include that information.

I like this organization method, feels very ADHD-friendly

does it support custom domains?

Do you have a calendar?

Not sure if you know this but with Gmail (and I bet that almost with any other email service) you can approach this - instead of the '-' character you use a '+' and set custom filters and tags for each '+' you want. I've been doing this for ages with it - though as a third world person I can't afford privacy by paying a third party subscription nor setting a home server and running local services 24/7 by paying more electricity.
