FAQ

Email verification questions

What's a catch-all domain?

A domain that accepts mail for any address. The server says yes whether or not the mailbox exists, so these addresses are flagged as risky rather than valid.

Does verification send an email to the address?

No. The checks look at the address, the domain and the mail server's response, without delivering a message.

Can I verify addresses automatically?

Yes. Send them through the API, or connect an automation tool that can call a REST endpoint.
