What Google Postmaster Tools data covers G Suite domains versus Gmail.com?

Key findings

• Reputation data inclusion: Google Postmaster Tools includes IP and domain reputation data for all domains handled by Google, which encompasses both Gmail.com and G Suite (Google Workspace) recipient domains.
• Other metrics exclusion: Dashboards like Spam Rate, Feedback Loop, Authentication, Encryption, and Delivery Errors generally report data only for emails delivered to Gmail.com addresses.
• Domain verification: To access any data, your sending domain must be added and verified in Google Postmaster Tools.
• Subdomain data: Subdomain data typically rolls up to the root domain in GPT dashboards, regardless of whether it's G Suite or Gmail.com traffic.

Key considerations

• Target audience matters: If your primary recipients are G Suite domains, the domain and IP reputation dashboards are highly relevant, as they reflect your standing with Google's broader ecosystem. However, for Gmail.com users, all dashboards are applicable.
• Interpreting 'no data': If you see no data for certain metrics, it could be due to insufficient volume to Gmail.com accounts, not necessarily a lack of G Suite traffic.
• Comprehensive analysis: While GPT offers valuable insights, a complete understanding of your email performance requires combining this data with internal sending statistics and other deliverability monitoring tools.
• Data scope: It is essential to remember that Google Postmaster Tools provides insights specifically into mail sent to Google's receiving infrastructure, not mail sent from Google Workspace accounts directly.

Key opinions

• Initial assumption: Many marketers initially believe Google Postmaster Tools data is solely for Gmail.com recipients, excluding Google Workspace (G Suite) domains.
• Observed G Suite data: Some marketers have observed Postmaster Tools data populating for their G Suite hosted email applications, particularly concerning TLS encryption rates from their own IP addresses.
• Reputation insights: There is a general consensus that domain and IP reputation data is more broadly applicable across all Google-handled domains, including G Suite.
• Specific use cases: The inclusion of G Suite data in GPT might be more evident in isolated scenarios, such as when sending internal emails from a specific IP to a G Suite domain.

Key considerations

• Data granularity: Marketers should focus on which specific dashboards provide data for their target audience, whether Gmail.com or G Suite, to avoid misinterpreting missing data as a broader issue.
• Confirming scope: If a marketer needs to verify the exact scope of data for G Suite domains, it's best to cross-reference with Google's official documentation or support channels, as interpretations can vary.
• Holistic view: While Google Postmaster Tools is a critical component, marketers should always combine its insights with data from their own sending platforms and other deliverability tools for a complete picture.
• Adapting strategies: The distinction in data coverage means marketers must adapt their monitoring strategies based on their recipient base, focusing on reputation for G Suite and all metrics for Gmail.com.

Key opinions

• Comprehensive reputation data: Experts confirm that Google Postmaster Tools provides IP and domain reputation data for all domains handled by Google, including those using G Suite for their email.
• Specific metric limitations: Other detailed metrics such as spam rate, feedback loop, and authentication reports are typically confined to traffic directed at Gmail.com addresses.
• Internal verification: Information from direct contact with Google personnel suggests this is the verified and current operational model for GPT data.
• Importance of reputation: The fact that reputation data covers G Suite domains means these metrics are highly relevant for B2B senders targeting businesses using Google Workspace.

Key considerations

• Evolving policies: While current information indicates certain data exclusions, Google's policies can evolve, necessitating ongoing monitoring of official documentation.
• Data interpretation: Experts advise caution in interpreting GPT data, especially when dealing with low email volumes to Gmail.com, as this can lead to delayed or missing data.
• Targeted improvements: If you primarily send to G Suite domains, focus on maintaining a strong IP and domain reputation. If Gmail.com is a key target, address all Postmaster Tools metrics.
• Authentication impact: Proper authentication (SPF, DKIM, DMARC) is foundational for all Google recipients, including G Suite, and directly impacts the reputation scores seen in GPT.

Key findings

• Domain verification requirement: Documentation states that Postmaster Tools requires domain verification to uniquely identify email traffic, indicating that data is tied to the sending domain, regardless of recipient type.
• Focus on reputation: The overview of dashboards often places IP and Domain Reputation first, implying their fundamental importance across Google's entire mail system, not just Gmail.com.
• Implicit G Suite coverage: While not explicitly stating 'G Suite data included', the API documentation for gathering metrics on bulk emails to Gmail users can be interpreted to include all Google-managed inboxes.
• Volume thresholds: Documentation consistently mentions that data is only shown if there is a significant daily volume of email traffic, primarily to Gmail.com users.

Key considerations

• Reading between the lines: Marketers need to interpret Google's general statements about 'Gmail users' to understand whether they encompass all domains that receive mail via Google's infrastructure.
• API context: The Postmaster Tools API overview indicates that the tool allows gathering metrics on bulk emails sent to Gmail users, suggesting a broad coverage of all mail filtered by Google.
• Domain vs. mailbox: Documentation distinguishes between domain-based data (like reputation) and recipient-based data (like spam rate), implying that domain-level metrics inherently apply to all mail flowing through Google's systems for that domain.
• Support resources: For definitive answers, senders are often directed to Google's official support channels or developer documentation, which can provide more granular details on data scope.
