As an administrator, you can customize how email is routed and stored to meet your organization's requirements.
Gmail split delivery lets you deliver incoming email messages to 2 different email systems in your domain, based on recipients you specify. For example, use split delivery when some people in your organization use Gmail and other people use a different email system. You can also use split delivery when you migrate from another email server to Gmail.
Step 1: Add your non-Gmail server in the Admin console
Before you can set up split delivery, you must add your non-Gmail server with the Add Route setting.
Step 2: Set up split delivery
In this step, you'll add the split delivery setting, and reference the server you added in Step 1.
