Frequently Asked Questions

Is this truly Pay-Per-Result?

Yes. Pricing starts from $0.95 per 1,000 results. No monthly rental fees.

How many emails can I verify at once?

There is no hard limit. You can process hundreds or thousands of emails in a single run with concurrent checking.

What does “catch-all” mean?

A catch-all domain accepts all emails even if the specific mailbox does not exist. These are marked separately so you can decide whether to send.

Will verification hurt my sender reputation?

No. The process uses SMTP probing techniques and does not send actual emails to the addresses being checked.
