I have no idea, it’s an old email I used for a lot of services before I knew about email aliases like Mozilla relay.

Like I said, most of them are useful once, like a shipping notification or a sign in security code. But most of the time I just copy the code from the desktop notification and leave the email. I don’t know why so many services moved from a password based login to email security codes, it’s annoying that’s for sure.

I’ll try to set up some filters to delete them after a day.
