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.
| Spam settings | Add senders to an allowlist based on their email address or domain name. Create an allowlist of approved senders by following the steps in Customize spam filter settings. |
| Approved sender lists | Add email addresses and domains to allowlists with the address list option in these Gmail settings: Blocked senders, Restrict delivery, Secure transport (TLS) compliance, Content compliance, Attachment compliance, Objectionable content, and Routing. |
| Inbound gateway setting | If you have receiving mail servers that process your mail before sending to Gmail's servers, add them to the Inbound Gateway setting. Follow the steps in Set up an inbound mail gateway.
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. |
