Hi HN, my email provider pulled a fast one on me over the weekend - overhauling their UI and dropping their regex alias functionality without warning. Not what you want from a paid service.
I very successfully operate a <site>.<date>.<nonce>@<mydomain> schema for personal email, using regex aliases to manage "users", and blacklists to eliminate spam. The largest draw of this schema is detecting when companies are breached / leak my data (4 times in 6 years), and when some company misuses information I gave them for something else (countless times).
I also use it to manage alerts and priorities for a handful of custom systems to special mailboxes.
Not every email provider can support such a schema, and until today I was very happy with mine - charging only for a ceiling on daily sends and total mailbox size with unlimited mailboxes.
I don't want to go back to managing my own email (though if I have to I will) - do you guys have any recommendations?
Multiple rules can be ANDed or ORed as well, if you don’t want to make a single regex that’s more complex.
