What is a catch-all email domain?
A catch-all domain is a mail setup that accepts messages sent to any address at that domain, even an address that does not exist.

Why does this matter?
A checking tool cannot tell whether a person's mailbox is real, since the domain says yes to everything. Tools often label these as "accept all" or "unknown" rather than valid.
What should you do?
Send a small number first and watch for replies and late bounces. A personal, specific message lowers the harm if an address is wrong, because you only sent one.
