Are there any email services which allow basically unlimited aliases with long, random names?

I'm using my own domain right now, but that can only uncover who has leaked my data; does not provide additional privacy.

Another commenter mentions ProtonMail, but somewhat unadvertised is with a paid Proton sub (I forget which tier), you also get access to SimpleLogin. It's a service which lets you create new email aliases with your domain that just send them to another email you own. (Also lets you send emails as that alias, so the other end doesn't see your real address.)

I use it with Vault/Bitwarden, which lets me generate email addresses of format `<uuid>@my.domain.com` when I create new login info for services.

I know you can set up "catch-all" email with a custom domain through Proton Mail.

I don't think there's any limit on gmail + codes.

Use a catch-all inbox. Fastmail supports them well in its web interface. I use unique addresses for every organisation.

The problem with catch-all inbox is when you have to reply to an email. Then you have to create the email address to be able to send emails from it. Or are there other solutions?

duckduckgo's free email aliases. Can use it as a front-end and keep your existing domain

I misphrased my query; I already run my own mail server and am using a unique e-mail address for every service. I'm wondering if there's a provider with a common domain name shared between lots of users that still allows such a large number of aliases. That would let me use a fake name for anything that doesn't need my real identity, and wouldn't reveal my identity in the case of a breach. Has any e-mail provider found a way to implement this while preventing abuse?

check simple login. they were both by Proton, but you can use them without the parent.

proton unlimited, i think. mail plus doesn't seem to do it, which kinda sucks.
