My emails are being sent from a generic Google domain

If your emails are unexpectedly being sent from a generic Google domain (such as appstempdomain.google.com) instead of your usual Google Workspace account, it’s usually caused by a conflicting account situation. This happens when you have both a personal Google Account and a managed Google Workspace account created with the same email address.

Conflicting Google Worskpace accounts

Why does this happen?

When Google detects that the same email address is tied to both a personal Google Account and a managed Workspace account, it creates a conflict.

If the conflict isn’t resolved, Workspace may temporarily route emails through a placeholder domain such as appstempdomain.google.com instead of your organization’s domain.

How to fix it

First, resolve the conflicting account in Google:

  1. Sign out of all Google services.
  2. Sign back in using the conflicted email address.
  3. Google will detect the conflict and prompt you to resolve it (choosing which account to keep, or renaming the personal account).
  4. Follow the on-screen steps until your accounts are separated and the conflict is resolved.

More details are available on Google’s support page.

After resolving the conflict in Google, reset your Mailmeteor sender:

  1. Open Mailmeteor Dashboard
  2. Access your account Settings > Senders.
  3. Delete the affected sender.
  4. Add the sender again, which forces a fresh connection to the correct Workspace account.

Example scenario

You originally created a personal Google Account with [email protected]. Later, your company provisioned a managed Workspace account with the same address. Because of this overlap, Gmail may send messages from appstempdomain.google.com instead of your company’s real domain.

Once you resolve the conflict and reset your Mailmeteor sender, messages will send correctly using your organization’s domain.

In summary

If you see emails sent from appstempdomain.google.com, it means your Google account is in conflict. Sign out, sign back in to resolve the conflict, and then reset your sender in Mailmeteor. This ensures your emails are delivered from the correct domain.
