A catch-all email is a mailbox configured to receive all emails sent to any address at your domain, even if that specific address doesn't exist. For example, if someone emails typo@yourdomain.com and that address doesn't exist, a catch-all mailbox would still receive it. This prevents lost emails due to typos but can also attract more spam. Catch-all configurations are set up through your email hosting provider.
