Catch-All Email Verification with Real Verdicts
Most verifiers stop at catch-all and accept-all domains. TargetPulse confirms the true existence of each mailbox, including addresses sitting behind Secure Email Gateways like Mimecast and Proofpoint, with 99% accuracy.

On a typical list, around 30% of emails sit on catch-all domains. We verify each one and most turn out to be valid.
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.
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.
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.
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.
Clear Results
From guesswork to clear verdicts
See the difference between a typical verifier and TargetPulse on the same list of 48,000 emails.
Over 10,000 catch-all contacts you cannot confidently send to. Around 80 percent of them are real, but you have no way to know which.
Around 8,400 more deliverable contacts recovered from the catch-all pile. Every address gets a clear verdict.
