Add IP addresses to allowlists in Gmail
Help prevent messages from certain IP addresses from being marked as spam by adding them to an email allowlist. Messages from these addresses won't be marked as spam by Gmail.
Email allowlists are always applied to your entire domain. You can’t create email allowlists that apply to specific organizational units only.
These settings also help you prevent messages from specified senders from being marked as spam.
Important: If you enter an IP address in an inbound gateway configuration, then add the same IP address to an email allowlist, the IP address won't be added to the allowlist. This is due to how Gmail determines the true sender, or source IP address.
