I've also been using sneakemail for at least twelve years. They also let you set up addresses with a bunch of randomly generated letters/numbers that are opaquely mapped to you, but you have to log in to do that.

The only problem is that some sites ban their domains - in particular Adafruit does this (they banned existing use of it, not just new sign ups), and their support said basically "we won't whitelist your address even though you've been ordering stuff from us for over five years".
