Bulk Email Validator — MX, Format & Disposable Check

What does Bulk Email Validator do?

FAQ

Does this guarantee an email can receive mail? MX record validation confirms the mail server exists, but cannot guarantee the specific mailbox is active without sending a test email.

Is disposable email detection comprehensive? The Actor checks against a large database of known disposable email providers. New providers may not be flagged immediately.

Is this Actor maintained? Yes. Report bugs or feature requests in the Issues tab.
