Postmaster Tools API now available

Quick launch summary

We’re launching a Postmaster Tools API, allowing programmatic access to the email data found in the Postmaster Tools user interface. You can use the API to gather metrics on bulk emails sent to Gmail users—such as delivery errors, spam reports, feedback loop performance, and more. You can also import or merge the data into other systems and diagnose issues with email delivery.

Getting started

  • Admins: There is no admin control for this feature. 
  • End users: Registered domain owners can use this API to programmatically extract their domain’s data into their systems. Check out the Developers Guide to learn more about the using the Postmaster Tools API.

Rollout pace


  • Available to Google Workspace Essentials, Business Starter, Business Standard, Business Plus, Enterprise Essentials, Enterprise Standard, and Enterprise Plus, as well as G Suite Basic, Business, Education, Enterprise for Education, and Nonprofits customers
