The Background

What is a catch-all email domain?

A catch-all domain accepts every email sent to it, even addresses that do not exist. The server replies with a generic acceptance to any address, so a normal SMTP check cannot tell you whether a real mailbox is behind the address.

On a typical sales or marketing list, around 30 percent of contacts sit on catch-all domains. Most verification tools see that pattern, give up, and label everything as Risky or Unknown. You end up with a long list of contacts you cannot confidently use.

That leaves two bad choices. Send to them and risk bounces, spam traps, and a damaged sender reputation. Or delete them and lose real customers you could have reached. Catch-all verification solves this by checking the actual existence of the mailbox instead of guessing.

How It Works

How TargetPulse verifies catch-all emails

Every catch-all address goes through multiple layers of verification that combine into a single clear verdict. You see Valid or Invalid, not a technical report.

1

Deep Mailbox Verification

We confirm the true existence of each mailbox, not just whether the domain accepts everything. Where standard SMTP checks see a generic acceptance and stop, we keep going until we reach a real answer.

2

Domain Trust Signals

We review the authentication setup of every domain: SPF, DKIM, DMARC records, SSL certificates, and hosting reputation. Domains configured properly are far more likely to host real mailboxes.

3

SEG and Gateway Handling

Addresses protected by Secure Email Gateways such as Mimecast, Proofpoint, and Barracuda are verified directly. The gateway no longer hides whether a real mailbox sits behind the address.

FAQ

Catch-all verification questions

A catch-all domain accepts every email sent to it, even addresses that do not exist. The server simply replies "yes, this exists" to any address, which is why traditional SMTP checks cannot tell you whether the mailbox is real.

A standard verification is a single check. A catch-all verification runs deeper, including direct mailbox checks on addresses protected by Secure Email Gateways. The extra work is the reason a catch-all check costs 1.5 credits instead of 1.

Around 99% on standard business lists. Instead of guessing based on SMTP responses alone, we verify the true existence of the mailbox so the verdict you see is the one that holds up when you actually send.

No. Catch-all checks run alongside your regular verification, not after. Your full list still completes in the same window.

Yes. Open Catch-All Detection in your dashboard, paste or upload only the addresses you want to check, and verify just those.

That is rare, but if we cannot reach a verdict the credit is refunded automatically. You only pay for verifications we can complete.
