Custom webmail domain
Your mailbox, at your own address.

Planned for Enterprise. Your team signs in at mail.yourcompany.com and sees your brand, while we run everything behind it.

In short

What is a custom webmail domain?

It is the web address people type to open their email. With one, that address is on your domain instead of ours.

How it works

One record to point it

Add a CNAME for the host you choose. We issue the certificate and keep it renewed.

Your brand at the door

The sign-in page and the app carry your mark and logo, the way Workspace branding already does in the sidebar.

The mail stays where it is

Addresses, domains and their DNS records do not change. Only the address people open changes.
