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.

The consensus is that while Google Postmaster Tools (GPT) offers some insights into email deliverability and reputation, particularly for Gmail addresses, it has limitations for monitoring B2B G Suite domains. To gain a comprehensive view of email reputation across various B2B domains, it is recommended to use a combination of methods including monitoring bounce rates, feedback loops, sender authentication (SPF, DKIM, DMARC), blocklists, and maintaining a clean email list. Several experts also recommend using third-party tools to monitor deliverability and sender reputation for various email providers, including G Suite, as these tools offer insights beyond what Google Postmaster Tools provides. Permission-based email marketing and actively managing email lists are also considered essential for B2B success.

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.

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.
