Check any email address

Paste an email address, and an IP if you have one. No account needed. The disposable email checker page explains each check.

We do not store the email or IP you type, and keep no history of your checks. The email's domain stays in our DNS cache for up to an hour, a hash of your own IP address is kept for up to 24 hours for rate limits, and we count how many checks end in allow, challenge or block each day. Details.
