Does Gmail have a traditional FBL? (Hint: Google Postmaster Tools)

Gmail does not offer a traditional FBL that sends individual complaint notifications. This is a significant gap for senders because Gmail processes over 30% of global email.

Instead, Gmail provides aggregate complaint data through Google Postmaster Tools. You can see your overall spam rate percentage, but you cannot identify which specific recipients complained.

This means you cannot suppress individual Gmail complainers the way you can with Microsoft or Yahoo. You must rely on proactive list hygiene, engagement-based suppression, and preference management to minimize Gmail complaints.

Gmail is like a port that publishes aggregate complaint statistics but does not name individual complainants. You know your reputation score, but identifying specific unhappy merchants requires detective work.
