Catch-all Domain
A domain configured to accept emails to any address, making it impossible to verify specific email addresses through standard methods.
What is Catch-all Domain?
A catch-all domain is configured to accept all incoming email, regardless of whether the specific mailbox exists. If you email john@catchall-company.com or nonsense@catchall-company.com, both will be accepted.
Why catch-all matters for cold email:
Standard email verification works by asking the server "does john@company.com exist?" For catch-all domains, the answer is always "yes" - even for non-existent addresses.
This creates a verification problem:
- About 40% of business domains are catch-all
- Standard verification can't distinguish valid from invalid
- You might send to addresses that don't exist
- Bounces damage your sender reputation
Our solution: We use proprietary verification methods that can verify approximately 80% of catch-all addresses that standard verification cannot - reducing your bounce risk significantly.
