Verify Catch-All Email Addresses at Scale

The Catch-All Email Verifier helps you get a clearer answer on email addresses that standard verification tools mark as catch-all. Upload your list and LeadsFriday runs those addresses through Catch All Verifier and BounceBan for deeper verification.

A catch-all domain is configured to accept messages sent to almost any address on that domain, which makes it difficult for standard verification tools to confirm whether a specific mailbox actually exists.

Because catch-all mail servers can accept verification requests even when the individual mailbox may not exist. This often leaves regular verification tools unable to confidently classify the address as valid or invalid.

We run your catch-all addresses through Catch All Verifier and BounceBan to perform deeper checks and return more actionable results than a standard catch-all status alone.

Upload a CSV containing your catch-all email addresses, map the email column, review your selection, and submit the request. We’ll process the verification and return the results in your completed CSV.

Your completed file includes your original email data along with the available catch-all verification result, helping you decide which addresses to keep, review, or remove before sending.

Yes. You can upload a small list or process thousands of catch-all email addresses at once. Larger files may take longer to complete.

Processing time depends on the size of your list and the verification required for each address. Most requests are processed automatically, so you don’t need to keep the page open.

No. Catch-all verification can provide a stronger signal, but no verification method can guarantee delivery. Mailboxes and mail server behavior can change after an address is checked.

The cost depends on the number of catch-all email addresses you submit. You’ll see the applicable credit cost before confirming your request.
