Fed up of having to sign up for disposable email addresses whilst testing applications?
Simply use the following email format:
pete+junkmail@republicofpete.net
Replace the junkmail part with a unique label each time you need one. They will always go back to your email account and will have an easy way of identifying them.
This also works well when you’re trying to work out where your details get sold on to so you can block them easily.
Caveat: Some SMTP servers are unable to handle the routing of these types of email addresses. I would suggest using a Gmail account for testing as these labelled email formats work like a charm.
