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 don't store the email or IP you type, or any history of your checks. But we keep the email's domain in our DNS cache for up to an hour, and a hash of your own IP address for up to 24 hours for rate limits. We also count how many checks end in allow, challenge or block each day. Details.
