What is Catch all?
The email server has been set to receive all emails whether email address exists or not. Emails sent to ‘catch all’s might be delivered to a different email address, or might not be read at all. Additionally, in some cases emails sent to catch all domains might bounce. Many businesses use catch all servers.
