Some Gmail reports have details about inbound, outbound, and internal mail. This article defines each message type.
Notes:
- Messages sent and received with SMTP relay service aren't included in the message totals in aggregate reports.
- In the table below, an associated domain is any domain or subdomain of the parent domain that is a primary, secondary, or alias domain.
| Message Type | Description |
|---|---|
| Inbound | Messages received by your users from senders outside the set of associated domains for your organization. |
| Outbound | Messages sent by your users to recipients outside the set of associated domains for your organization. |
| Internal |
Sending—Messages sent by your users to recipients within your organization's associated domains. Receiving—Messages received by your users from senders within your organization's associated domains. Important: Messages must be authenticated by either SPF or DKIM to be treated as internal. This applies even to messages from associated domains. If a message sent from an associated domain does not pass either SPF or DKIM, it's treated as an external message. |
| Delivered | Messages delivered directly to or from Gmail, or to the default mail route (for non-Gmail mailbox users). Rerouted messages that are delivered aren't defined as delivered because Gmail is not the final destination. |
| Rerouted | Messages rerouted to another server from Gmail. |
| Rejected | Messages that are rejected. Reasons for message rejection vary by direction (inbound/outbound). Rerouted messages that are rejected aren't defined as rejected because messages are rerouted before they're rejected. |
