Disposable Email Checker
Reviewed: 18 September 2026
Check whether an address uses a disposable (throwaway) domain. Enter one address: only the domain part is sent to our server for the lookup — never the full address, and nothing is stored.
Domain list: 121,569 domains from the open disposable-email-domains list, last refreshed 2026-09-18.
What this check does and does not tell you
A disposable result means the domain is a known throwaway provider. Not listed means the domain is not on that list — it says nothing about whether the mailbox exists or will accept mail. This is a domain-level check: no mailbox verification is performed here.
Cleaning a whole list?
This tool checks one domain at a time. The email list cleaner removes all disposable addresses from a full list in one pass, together with duplicates, dead domains and role addresses.
