You can use [MailSlurp](/api/) to catch all emails sent to a domain name using catch all inboxes. To set custom outbound and inbound rules for an inbox see the [inbox ruleset guide](/guides/inbox-rulesets/).

## Create a domain

First register a domain and [add the domain to MailSlurp](/guides/email-address-custom-domain-setup-step-by-step/).

[Verify the custom domain](/guides/custom-domains/) and view the catch all inbox that was created.
