Google Postmaster Tools (GPT) is an essential free resource for email senders to monitor their email deliverability performance to Gmail and Google Workspace recipients. However, it's common for users to encounter alerts such as "Data shown with missing records" or to observe gaps in their data. These occurrences can be concerning for marketers and deliverability professionals who rely on this data for insights into their email programs. This summary explores the various reasons behind missing or incomplete data in GPT, drawing insights from user experiences, expert opinions, and official documentation.
Key findings
Intermittent data: Google Postmaster Tools data can be intermittently unavailable or show missing records for various periods, ranging from a few days to longer stretches.
Volume thresholds: A primary reason for missing data is not meeting Google's minimum sending volume thresholds to Gmail recipients. While exact numbers are not publicly disclosed, consistent sending is crucial.
Backfilling: In cases of Google-side issues, data often gets backfilled once the problem is resolved, although this is not guaranteed for all instances of missing data.
Specific error messages: The "Data shown with missing records" alert indicates partial data availability, differing from a complete "no data to display" message that typically suggests insufficient volume.
Key considerations
Monitor sending volume: Ensure your sending volume to Gmail is consistent and high enough to generate meaningful data in GPT. Low volume is a common cause of data gaps, as explored in our guide on why Google Postmaster data is limited or intermittent.
Check authentication: Ensure SPF, DKIM, and DMARC are correctly configured, as authentication issues can lead to data not being processed. Our guide to SPF, DKIM, and DMARC can help.
What email marketers say
Email marketers often face challenges with Google Postmaster Tools displaying incomplete or missing data, leading to uncertainty about their email program's performance. The discussions among marketers highlight common experiences, differing error messages, and the impact of sending volume on data availability. They emphasize that while some issues resolve automatically, others may require closer examination of sending practices.
Key opinions
Common occurrence: Many marketers report that seeing missing data in Google Postmaster Tools is a common occurrence and not necessarily an immediate cause for alarm.
Google-side issues: There's a shared belief that if the problem stems from Google's end, the data will eventually be backfilled, though this isn't always reliable.
Volume impact: A significant factor for marketers is the volume of emails sent to Gmail addresses, with lower volumes often correlating with missing data.
Error message nuance: Marketers note a distinction between the "Data shown with missing records" alert and a complete "no data to display" message, suggesting different underlying causes for each.
Inconsistent data delivery: Some marketers observe that data availability can vary across different clients or domains, even when managed by the same sender, highlighting potential inconsistencies in GPT's reporting.
Key considerations
Acknowledge commonality: Recognize that missing GPT data is a frequent issue, which can help manage expectations and reduce immediate concern.
Review sending volume: Regularly check that your email volume to Gmail recipients is sufficient to trigger data collection. This aligns with advice on improving domain reputation which is tied to consistent sending.
Marketer from Email Geeks notes that Google Postmaster Tools (GPT) data gaps are a recurring issue for many users. They often observe that data may be missing for a few days, leading to temporary concerns about deliverability metrics.

What the experts say
Deliverability experts often provide a deeper understanding of why Google Postmaster Tools data might be missing, going beyond anecdotal observations. They emphasize the technical requirements for data population, the nuances of Google's algorithms, and the importance of consistent email sending practices to maintain data flow.
Key opinions
Minimum volume: Experts consistently highlight that not meeting Google's undisclosed minimum daily sending volume to Gmail is the most frequent cause of missing data in GPT. This applies to all dashboards, including IP and domain reputation.
Reputation impacts: A low domain or IP reputation can sometimes lead to reduced data visibility, as Google may treat traffic differently, affecting the data reported in GPT.
Authentication standards: Proper implementation of email authentication protocols like SPF, DKIM, and DMARC is crucial not just for deliverability but also for Google to trust and report on your email stream accurately.
System anomalies: Occasionally, missing data can be attributed to temporary system glitches or updates on Google's side, which are typically resolved, leading to data backfilling.
Key considerations
Consistent sending: Maintain a consistent and sufficient volume of email sends to Gmail recipients to ensure continuous data flow in GPT. This is a fundamental aspect of improving email deliverability.
Review authentication: Regularly check your SPF, DKIM, and DMARC records for proper configuration and alignment. Utilize DMARC record generator tools to assist.
Expert from SpamResource clarifies that Google Postmaster Tools requires a sufficient volume of mail to Gmail recipients for data to appear. Small senders or those with inconsistent volume may experience dashboards that remain empty or show missing records.

Expert from Word to the Wise advises that if your sending domain's reputation is low, Google may not provide comprehensive data. A poor reputation can lead to filtering, meaning less mail reaches the inbox for GPT to analyze.

What the documentation says
Google's official documentation and other authoritative technical resources provide specific reasons for missing data in Postmaster Tools and outline the requirements for data visibility. These resources serve as the primary source of truth for understanding the platform's behavior and troubleshooting common issues.
Key findings
Volume requirement: Google documentation clearly states that data is only shown when there is a sufficient daily volume of email traffic from your authenticated domain (and its IPs) to Gmail recipients. Specific thresholds are not disclosed publicly.
Authentication errors: Missing or inaccurate SPF, DKIM, and DMARC configurations can prevent Google from properly authenticating your mail, leading to no data being reported. For example, a DMARC fail error can cause data issues.
Daily aggregation: Data in GPT is aggregated daily, and it can take up to a few days for new data to appear. Delays in processing can lead to temporary gaps.
IP and domain reputation: If IP or domain reputation is very low, data might be scarce or missing because emails are being heavily filtered before they can contribute to sufficient volume.
Key considerations
Verify domain setup: Ensure your domain is properly verified in Google Postmaster Tools by adding the required DNS TXT record. This is the foundational step for any data collection.
Adhere to sending guidelines: Follow Google's bulk sender guidelines, which include maintaining a low spam rate, authenticating emails, and ensuring easy unsubscription. These guidelines directly impact data availability and deliverability, as detailed by MarTech's overview of new bulk email restrictions.
Monitor data refresh: Understand that GPT data is not real-time and often has a delay of 2-3 days. This delay can sometimes be perceived as missing data, as discussed in our article why Google Postmaster Tools is not updating.
Review help sections: Consult Google's official Postmaster Tools help sections for detailed explanations of dashboard metrics and troubleshooting tips for common issues, including data visibility.
