Summary
It is not possible to identify specific individuals who report emails as spam in Gmail due to the absence of a direct feedback loop (FBL) and privacy concerns. The focus should be on reducing spam complaints through various strategies. Key among these is improving email list quality by using double opt-in, regularly cleaning inactive subscribers, and preventing list bombing. Content relevance is crucial, necessitating segmentation and tailored content. Proper email authentication (SPF, DKIM, DMARC) is essential. Maintaining a positive sender reputation through best practices like warming up IP addresses and monitoring complaint rates (aiming for below 0.1%) is also important. Tools like Google Postmaster Tools and Microsoft SNDS provide aggregate data but not individual complaint details. Avoiding spam trigger words and engaging subscribers with valuable content further reduce the chances of emails being marked as spam.

Marketer from Email Geeks shares you can't know who complained with Gmail. Complaints happen, all you have to do is keep them low. One way of doing so is to highlight the unsub link, at the top of your email, so people would unsub instead of complain.

Expert view
Expert from Spam Resource details that Feedback Loops (FBLs) are mechanisms used by ISPs to forward complaints from their users about specific emails. Unfortunately, not all ISPs offer FBLs and even when they do, you generally can't get user-specific information due to privacy concerns. Using an FBL allows you to remove users who are marking your messages as spam. Gmail does not offer a traditional FBL.

Google Postmaster Tools provides aggregate spam rate data for your domain but does not reveal individual user complaints. While RFC Editor defines the Abuse Reporting Format (ARF) for feedback reports, Gmail doesn't fully support sending individual complaint reports. Microsoft's SNDS provides IP reputation data and complaint rates specifically for Outlook.com, but also lacks individual user data. The overall emphasis is on monitoring aggregate metrics to assess email sending practices.
Key findings

- Aggregate Metrics: Google Postmaster Tools and Microsoft SNDS provide aggregate data on spam rates and IP reputation.
- Limited Gmail Support for ARF: Gmail does not fully support sending individual complaint reports using the Abuse Reporting Format (ARF).
- Outlook.com Data via SNDS: Microsoft SNDS provides complaint rate information specifically for email sent to Outlook.com users.
Key considerations
- Monitor Aggregate Metrics: Regularly monitor aggregate spam rates and IP reputation using tools like Google Postmaster Tools and Microsoft SNDS.
- Focus on Best Practices: Implement and maintain best practices for email sending, authentication, and content to reduce spam complaints.
