Email Log Search delivery status definitions

Definitions for message delivery status, post-delivery status, and spam classification

Email Log Search (ELS) search result details include status information for each message in the search results. ELS results include two status types for messages:

ELS message delivery status

Message delivery status is included in detailed ELS results. The delivery status describes the state of the message at a specific step during the message delivery process.

Status Description
Archived This message is part of a Google Groups discussion that has conversation history turned on. The message is available on the group page.
Accepted for archiving The message has been accepted for archiving by Google Groups.
Bypassed spam

The message was marked as spam but was delivered normally to the recipient because of a spam filter setting.


The message bounced because of issues with the email account. Issues can include: your IP address is blocked, your account reached sending or receiving limits, or the message violates a compliance or routing policy rule

Delivered The message was delivered to the recipient’s Gmail inbox or third-party SMTP server, which is included in the ELS results Message details. If the message is missing, get the IP address where the message was delivered. Then, check your external network for issues.
Delivered to a Google internal server A Google service generated the message and handed it off to that service for delivery. This status doesn't indicate whether the message was delivered to the recipient.
Delivered to an SMTP server The message was delivered to the SMTP server with the specified email address and encryption.
Delivered to Gmail inbox

The message was delivered normally to the recipient. If the message is missing, the recipient might have deleted it, archived it, or moved it to a label. The account owner can search all mailboxes and labels, or use Gmail advanced search to try to find the message.

Delivered to group for distribution to members The message was delivered to a group address for expansion to individual group members.

The message wasn’t delivered because the sending server has a bad reputation. Multiple factors can impact server reputation, including spam reports, recipient engagement, and bounce rates. This status is also applied when the message is affected by a Gmail catch-all or routing rule.

Forwarded by group The message was sent to the recipient following a group expansion.
In progress

The message is passing through Google’s servers on the way to its destination.

Inserted into Gmail delivery pipeline

The Google SMTP server got the message and put it into the Gmail delivery pipeline for delivery to recipients.​

Inserted into Gmail delivery pipeline by the comprehensive mail storage service

The domain uses comprehensive mail storage, which stores a copy of all sent or received messages in your domain. When the storage setting affects a message, ELS shows SYSTEM_OF_RECORD .

Marked spam

The inbound message was classified as spam by Gmail. To fix misclassified messages, visit Mark or unmark Spam in Gmail. Messages marked as spam have a spam classification, described in ELS spam classifications, in this article.

Missed upload deadline

The recipient's SMTP server didn't respond to the Gmail SMTP server's DATA payload in enough time. The recipient’s email administrator should resolve this issue.

Opened Information about each time the message was opened. Each entry includes: Date and time the message was opened, the IP address of the device where the message was opened, the unique device session identifier, and the Gmail client type, for example web, Android, or iOS. 

The message triggered a setting that resulted in the message being quarantined. Review the message in Admin Quarantine to decide if the message should be delivered or rejected.

Received from a Google internal server

The inbound message was originally sent from a Google Workspace account, possibly your own organization. If this status appears multiple times in the Recipient details, the message likely originated from a Google Workspace account outside the recipient’s domain.

Received from an SMTP server

The inbound message was received from a message transfer agent at the IP address shown. This line also shows whether the message was encrypted with TLS. If you use TLS IMAP with Microsoft Outlook, and messages are received with TLS, messages are encrypted between the Gmail server and the sending host. To turn on TLS encryption for your own organization, use the Secure transport (TLS) compliance setting.


The message is marked as spam by automatic outbound spam filtering. For help with resolving this issue, visit Email bounces with error message.

Rejected from quarantine

An administrator checked the message in the email quarantine and deleted it. The most common reason for message deletion is that the message is spam.

Released from quarantine

An administrator inspected the message in the email quarantine and determined it was not spam. The administrator removed the message from quarantine so it could be delivered to the recipient.

Sent for archiving The message was sent for Google Groups archiving.
Sent for moderation The message is part of a Google Groups discussion. The message was sent to the moderation queue for review by the group moderators.
Sent from Gmail The message was sent from Gmail.
Sent to group members The message was sent to the individual group members.
