They work by giving you a random email address that is available for a short time (ex. 10min) and an inbox for any messages you recieve during that time (ex. an email verification message from a Lemmy server)
I didn’t want to recommend a specific one, however Googling “temporary email” should give you several options to choose from.
Anybody got suggestions for a temp (or not) virtual phone number? Like Google Voice but give you the ability to have more than one, and delete it?
