Disposable email checker: common questions
What is a disposable email address?
An inbox that exists for minutes or hours, used to receive a single confirmation email without revealing a real address.
Should I block relay addresses too?
Usually not: Apple Hide My Email and similar relays forward to a real person. We report them as "relay" so you can decide.
Where does the list come from?
Public, permissively licensed lists plus our own detection. You can download the full list from the open data page.
