Terms of service

Using Mail Exchange

You may use Mail Exchange to verify email addresses you have a lawful reason to hold, and you're responsible for following anti-spam and data-protection laws that apply to how you then email them.

Credits

One credit verifies one address. Credits don't expire. Unknown results and duplicates are refunded as credits.

Free trial

The trial lasts 3 days from sign-up and includes 25 email checks. You must give your real name, a work email and a valid payment card (prepaid cards are not accepted). The card is saved only to prevent repeat or abusive signups and is not charged for the trial. We allow one trial per person and per card, and we may refuse or end a trial we believe is abusing this limit. When the trial ends, nothing is billed; you can buy credits if you want to continue.

Accuracy

Verification reflects what mail servers report at the time of the check. Mailboxes change, and some servers give misleading answers, so we can't guarantee that every deliverable address will accept every message.

Acceptable use

Don't use the service to harvest or guess addresses, to probe systems you're not allowed to, or to support sending unsolicited bulk email in breach of the law. We may suspend accounts that do.
