GPTMail Now Publicly Lists All Available Domains

GPTMail now provides a public domain status page where anyone can view the full list of domains available on the platform.

This update makes domain availability more transparent. Instead of guessing which domains are supported, users can now open the Domains page and see every configured domain in one place, along with its current availability and MX health status.

Why we added this

GPTMail has grown to support a large number of domains. A simple dropdown selector is no longer practical when the list contains more than 1,000 domains. It slows down the interface, makes discovery harder, and does not scale well for users who only want to check whether a specific domain is available.

At the same time, domain information is not truly private. Domains that point MX records to GPTMail can often be discovered through public DNS data. Providing an official status page gives users a cleaner, more accurate, and easier way to check domain availability directly from GPTMail.

What you can see

The new Domains page shows:

  • The full public domain inventory
  • Whether each domain is active
  • The current MX status
  • When the domain was added
  • Search and filter tools for quickly finding a domain

We intentionally keep the page focused on user-facing status information. Internal details such as raw MX records and domain expiry data are not shown, because they are not necessary for normal GPTMail users.

Add your own domain

The page also supports self-service domain submission. If you own a root domain, point its MX record to the required GPTMail target and submit it from the Domains page.

Once the MX check passes, the domain can become available on GPTMail, and an API key may be issued for server-side usage.

A more transparent GPTMail

This change is part of GPTMail’s move toward a more open and self-service experience. Users can now verify supported domains directly, check domain health before generating addresses, and connect their own domains without needing manual support.
