🗑️ Disposable Email Detector
Flag throwaway, temporary and burner email domains — one address at a time, or a whole pasted list.
About Disposable Email Detector
Disposable (a.k.a. temporary or burner) email services like Mailinator, 10MinuteMail and Guerrilla Mail give out short-lived inboxes that anyone can read without signing up. People use them to dodge verification, abuse free trials, or sign up without leaving a real address. This tool checks an address's domain against a curated blocklist of known disposable providers so you can reject or flag them at signup.
Use the Single tab for one address, or the Bulk tab to paste a list (one per line) and see a clean/disposable verdict for each, plus a summary count. A "not disposable" result only means the domain isn't on the blocklist — it doesn't guarantee the mailbox exists; for that, run the address through the Email Validator. To inspect a domain's full mail configuration, use the Email Deliverability Checker.
