Gmail Postmaster Tools overview

This article describes the Gmail Postmaster site, tools, reports, and data. It also explains how to set up IP addresses and domains.

Gmail launched a new postmaster site in July 2015 to provide qualified, high-volume senders with tools and data to analyze their email. The site provides data and reports on IP and domain reputation, spam rates, delivery errors, and authentication.

Dashboards

Once approved and Gmail is receiving data for your domain , you have access to the following dashboards, which, with the exception of the Encryption dashboard, show only traffic that passed Sender Policy Framework (SPF) or DomainKeys Identified Mail (DKIM):

  • Spam Rate: Shows the volume of user-reported spam versus email that was sent to the inbox. Only email authenticated with DKIM is eligible for spam rate calculation.
  • Domain and IP Reputation: Presents data which indicates whether the Gmail spam filter might mark email from that domain or IP as spam.
  • Feedback Loop (FBL): Shows spam rates if you have implemented the Gmail FBL. Gmail FBL data is displayed in the dashboard only when the complaint rate is higher than 0.5%. The Gmail FBL was designed to help hosting companies detect bad entities on their networks. Because of this - as such, it does not operate the same as many other FBLs designed for bulk senders. The Gmail FBL may only be useful for very high volume senders with large complaint issues.
  • Authentication: Shows traffic that passed SPF, DKIM, and Domain-based Message Authentication, Reporting, and Conformance (DMARC).
  • Encryption: Shows Transport Layer Security (TLS)-encrypted traffic.
  • Delivery Errors: Shows blocks and temporary failures.

Gmail's help page provides more information about these reports.

These dashboards used in combination with the delivery and message-level information Inbox Monitor provides  can help you determine the reasons your messages may not be getting into your subscribers’ inboxes.

Getting set up

To get set up in the Postmaster system:

  1. Add and verify your authenticated domains.
  2. Prove you own the domain by entering the DNS TXT or the DNS CNAME.

Note: Gmail recommends that you follow its Bulk Sender Guidelines at all times to maintain a good reputation. 

Data
Data can be displayed for the last 7, 30, 60, 90 and 120 days. The maximum number of days for data available is 120. There is no custom date range function at this time.
