The domain doesn't belong to you

This domain is connected to another Buildy account, often an old one of yours. Remove it from that account first, or open Chat with support.

This message means the domain is already connected to a different Buildy account. Often it is an old account you created with another email.

If you connected the domain yourself

If you bought the domain somewhere else and connected it to the other account:

  1. Sign in to the other account and open the project that has the domain.
  2. Open Domain & Email from Dashboard, or Tools on a phone, then click the trash icon on the domain row.
  3. Sign back in to this account and add the domain again.

If the other account bought the domain through Buildy

Do not remove it there. Removing a domain bought through Buildy stops its renewal, and the domain stays with that account. Open Chat with support with the domain name.

Move a domain between your own projects

If the domain is on another project in the same account, Buildy offers the move in the app:

  1. Add the domain in the new project as usual.
  2. In the Move this domain here? dialog, read what moves: the website address and every inbox on the domain, with their mail and logins. The old project keeps its saved contact conversations.
  3. Click Move domain here.

Common problems

"This project already has a primary inbox."

The new project already has an inbox on another domain. Move the domain to a project without an inbox, or open Chat with support.

I do not remember the other account

Check which email addresses you have used with Buildy. See I can't find my projects. If you still cannot find it, open Chat with support with the domain name.
