Multiple sources, including email marketers, experts, and Google's documentation, indicate that delays and discrepancies are common in Google Postmaster Tools data. The delays stem from a combination of factors: Google's internal processing load, data aggregation algorithms, system maintenance, and potential changes in spam filtering. Sender-specific factors such as authentication, sending volume, and sender reputation also play a significant role. The tool is best used to identify trends over time rather than relying on specific daily data. Google Postmaster Tools only shows historical data so doesn't reflect real-time conditions or predict future outcomes and thus should be seen as an indicator. Discrepancies and delays could indicate deliverability issues, making it essential to audit email authentication settings and monitor sender reputation. Finally, as a free tool, its reliability and availability cannot be guaranteed.

Sender-specific factors such as authentication, sending volume, and sender reputation also play a significant role. Due to the tool's limitations and potential unreliability as a free resource, marketers should focus on identifying trends over time rather than relying on specific daily data points.

Experts from Spam Resource and Word to the Wise emphasize that Google Postmaster Tools provides historical data and isn't a real-time monitoring solution. Data delays are part of its inherent design. Therefore, it's more effective to focus on identifying trends and understanding the overall direction of your email program rather than getting caught up in daily fluctuations. Investigate significant deviations, but understand that day-to-day changes might not be meaningful.
Expert view
Expert from Spam Resource, Laura Atkins, explains that Google Postmaster Tools is a 'rear view mirror'. It shows you what happened but doesn't necessarily reflect real-time conditions or predict future outcomes. Data delays are inherent to its design and should be considered when interpreting the information.
