In regards to email aliasing services, addy.io is the only one I know of other than SimpleLogin, which is owned by Proton AG--so if you want to get away from Proton, SimpleLogin isn't an option. Both of these services are recommended on privacyguides.org.
Some email services allow you to use a domain you own, which theoretically should give you unlimited aliases to work with, but may not be as privacy-focused as the email address is only as anonymous as your registered domain.
Personally, I prefer the 'pseudonymous' aliases that addy.io and Proton Pass give (it's usually something like
random.words123@passmail.netin the case of Proton).If anyone has good experiences with other aliasing services that provide this option, please let us know.
How about just a mail service with a catch-all option? If you send an email to my domain that doesn't match any of my known addresses, it ends up in a catch-all box. That box order deletes mail every month and I just check it when I need it.
