Email validation confirms whether an address exists and can receive mail. It prevents bounces, protects your sender reputation, and keeps you off blacklists.
A catch-all domain accepts mail to any address, even ones that don't exist. We flag these so you know delivery isn't guaranteed.
Hard bounces occur when an email permanently fails—the address doesn't exist or the domain is invalid. Sending to these damages your sender reputation and can get you blacklisted.
