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.
