Custom domains
Alias can send forwarding aliases from domains you control.
Add the domain
Open the domains section and submit the domain you want to verify.
Publish the required DNS records
Alias provides TXT, MX, SPF, DKIM, and DMARC records. Publish them at your DNS provider exactly as shown.
Verify and start using it
Once the records validate, create aliases from your custom domain and route them like any other address.
