What is a catch-all email account?
A catch-all email account is an address that is specified to receive all messages that are addressed to an incorrect email address for a domain. For example, you have three email addresses set up for coolexample.com; [email protected], [email protected], and [email protected], you can set up [email protected] as a catch-all email account. Then, any email messages sent to [email protected] (or any other invalid email address), are sent to the catch-all account ([email protected]).
You can set up one email address as a catch-all account per domain name.
Catch-all accounts may receive excessive spam, as *@[domainname.com] is a much bigger target than individual email addresses. If your customer has a catch-all email address and complains about spam to the associated domain name, let them know why they're a bigger target.
