I think that having any kind of recognizable email is against the idea of privacy. So I would set up the following layering:
- Mozilla Relay/TempMail (randomized email accounts)
for most of shops, job applications, etc. If it leaks you can easily disable the account and/or rotate it on periodic basis to limit the cross-database matching (the privacy part) - a few separate domains for things where you can’t stop receiving mails or having an account is really worth it
- one for banks
- one for government
- one for the few shops where the first layer is not enough
- one for private exchange
- the provider that can change
I also switched to scripts. Aliases tend to break in loops with modified IFS
