I want a bulletproof way to give email sub-addresses, since some websites strip out special characters like + and .. I have an idea for how it could work, let’s say my email is TheTwelveYearOld@Reddit.com and I have the following:
- All emails sent to TheTwelveYearOld@ get blocked
- I specify a suffix that would be used instead of
+, perhaps “From” - I whitelist phrases that go after “From”: TheTwelveYearOldFromDoorDash, TheTwelveYearOldFromGoogle, TheTwelveYearOldFromReddit
Are there any services that can do this? I’m thinking I should make my own domain for emails that way my email addresses aren’t tied to any companies and I can easily switch.

The answer is yes. The receiver can do whatever they want with the “localpart” of the email address.
However you will need to find a provider that supports it. For available services you are probably looking at one of two options:
Toaddress however you want.If you want full control you can run your own email server. For example that is what I do. I generate addresses in the form of
{description}-{signature}@me.example. So if they try to remove stuff the signature will fail and the mail will get rejected (well actually just heavily weighted as spam). I do this using Rspamd with a custom rule written in Lua. Full details of this setup are here: https://kevincox.ca/2022/07/07/signed-email-addresses/
