Google Workspace Allowlisting Guide – NINJIO Help Center

Allowlisting Via DMI

The preferred method of allowlisting is through Google's Direct Message Integration.

You can find DMI setup instructions here.

If you prefer to allowlist through bypassing SMTP IPs, please proceed with the next part of this documentation.

You do not need to allowlist SMTP IPs once you have configured the Direct Message Injection.
