Summary
The general consensus is that while Google Postmaster Tools (GPT) provides some insights into email deliverability and sender reputation, it is limited for comprehensively monitoring B2B G Suite domains. GPT data is primarily focused on @gmail.com addresses, with only the reputation page reflecting some G Suite data. Experts and documentation recommend a multi-faceted approach, including using third-party tools and services, monitoring key metrics like bounce rates and engagement, implementing strong sender authentication (SPF, DKIM, DMARC), actively managing email lists, and sending relevant content. GPT is considered a good starting point, but dedicated reputation monitoring solutions are necessary for a complete B2B assessment.
Key findings
- GPT Limited Scope: Google Postmaster Tools primarily focuses on @gmail.com data, offering a limited view for B2B G Suite domains.
- Third-Party Tools Needed: Comprehensive B2B reputation monitoring requires third-party tools that cover a wider range of domains and ISPs.
- Multi-Faceted Approach: A combination of methods is necessary, including monitoring key metrics, implementing authentication, and managing email lists.
Key considerations
- List Management: Maintaining a clean, engaged, and permission-based email list is crucial for deliverability and reputation.
- Sender Authentication: Proper implementation of SPF, DKIM, and DMARC is essential for establishing sender legitimacy and improving deliverability rates.
- Engagement Metrics: Monitoring metrics like bounce rates, spam complaints, and engagement helps understand and manage sender reputation.
- Content Relevance: Sending relevant and valuable content improves engagement and positively impacts sender reputation.

What the experts say
4 expert opinions
The experts agree that Google Postmaster Tools (GPT) has limitations for monitoring email reputation for B2B G Suite domains. GPT data is primarily for @gmail.com addresses, with only the reputation page reflecting both G Suite and Gmail reputation. For a comprehensive view, relying solely on GPT is insufficient. Alternative third-party services, like Cloudmark (partnered with eDataSource) and Validity, offer reputation data across a wider range of domains and ISPs and are recommended for a more complete assessment.
Key opinions
- Limited GPT Scope: Google Postmaster Tools is limited in its scope, primarily covering @gmail.com addresses.
- G Suite Limitations: GPT doesn't provide a comprehensive view of reputation for G Suite domains, except for the reputation page itself.
- Need for Alternatives: Third-party services offer a more comprehensive solution for monitoring B2B email reputation across various domains and ISPs.
Key considerations
- Supplementary Resources: Exploring commercial seed list monitoring tools and third-party services is advantageous for gaining comprehensive insights beyond GPT.
- Data Ownership: Google doesn't own all the reputation data for its paying G Suite customers, impacting the data available in GPT.
- Alternative Tool Examples: Consider using services like Cloudmark (through eDataSource) and Validity for enhanced reputation monitoring.
Expert view
Expert from Spam Resource explains that while Google Postmaster Tools provides some insights, it's limited to Gmail/G Suite users. For comprehensive B2B reputation monitoring, you need to look at third-party services that cover a wider range of domains and ISPs.

What the documentation says
5 technical articles
The documentation indicates that while Google Postmaster Tools provides some data regarding sending reputation to Gmail users, including both standard Gmail and Google Workspace accounts, specific reports like spam rate and feedback loops are exclusive to @gmail.com users. To gain insights and manage sender reputation across a broader range of domains, including those outside of Gmail and G Suite, third-party services are recommended. Furthermore, implementing DMARC and SPF policies correctly is essential for establishing sender legitimacy and improving deliverability rates, especially for B2B communications. Microsoft's SNDS program is a similar tool to Google Postmaster Tools, but focuses on Microsoft email services, which is not applicable to G Suite.
Key findings
- Limited GPT Data: Google Postmaster Tools has data applicable to both Gmail and Google Workspace accounts, but some reports are Gmail-specific.
- Need for 3rd Party: Third-party services offer broader insights into sender reputation beyond Gmail and G Suite.
- Authentication is Key: Implementing DMARC and SPF policies is crucial for sender legitimacy and improving deliverability.
Key considerations
- DMARC & SPF Setup: Setting up and monitoring DMARC reports provides insights into potential authentication issues.
- Microsoft SNDS: Microsoft's SNDS program focuses on Microsoft email services and is not applicable to G Suite domains.
- Engagement Metrics: Engagement, spam complaints, and block lists are important metrics for B2B reputation monitoring with third-party services.
