I've been using Fastmail the past few years and I'm a great fan. Not alone does it allow me to generate up to 600 random email addresses using domains owned by Fastmail, it also supports catch-all email addresses using my own domains. Ever since I switched to Fastmail I've been able to use a unique email address for each online service that I sign up for.

Fastmail, several custom domains, catch-alls and '<service>.<month>.<year>.<nonce>@<domain>' has served me very well for the last 6 years.

Catch-all is definitely the way I prefer it, easier than having to generate an address with a service each time.

Even better is bitwarden can generate random emails @mydomain.com automatically when creating a new login.

Does anyone have a good self-hosted tool for doing this?

I use SimpleLogin aliases via my Proton subscription. But I'm terrified of what happens if I lose access to my Proton account, either because I get banned or the company disappears into a black hole. It would be a personal disaster to lose access to hundreds of accounts.

I could buy my own domains and have them forward to Proton but then they aren't disposable, unless I were to buy a domain for literally every account.

I'm in a similar boat with slightly different details, but I did get my own domain(s). To me this feels like another single point of failure. Now I'm not just worried about losing access to my email provider - I need to worry about the company managing my MX records too.

It's incredible how much information some people express through their email address. Patterns like:

"[firstname].[lastname].[year of birth]@gmail.com"

are still surprisingly common and indicate race, gender and age. These persistent addresses can also be cross referenced to various leaked datasets to get everything from phone numbers to dietary habits.

iCloud is almost justified by the number of expendable email addresses one can allocate
