AI Visibility Leaderboard
Email Services AI Brand Rankings
The current Email Services snapshot should be reviewed through rank, AI Index, mention rate, engine coverage, and latest refresh date.
Email Services tracks which products are most consistently surfaced by AI answer engines in this category. Use the overall ranking with the engine tabs to separate broad visibility from isolated engine strength.
The overall ranking gives a fast read on which products AI systems currently surface most often for Email Services prompts. The engine tabs add the important detail: they show where visibility is broad, uneven, or concentrated in one answer system. Rank alone is not enough. Mention rate, score gaps, refresh date, and engine-level outliers help show whether a product's position looks durable or depends on a narrower set of prompts and engines. Read this page as AI visibility evidence, not as a product-quality, compliance, safety, or market-share ranking.

How to read this page
This page uses the same leaderboard snapshot for its headline, visible metrics, and comparison table. Read rank together with visibility score: rank shows relative position in the current view, while the score records measured AI visibility. Nearby rows provide comparison context. Follow the related leaderboard links to compare the wider set of tracked entities and continue exploring pages based on the same snapshot.
Scores describe the data available for the snapshot date and should be read as a point-in-time comparison, not a permanent rating. Differences between rows show relative visibility within this leaderboard view. A later snapshot can change both rank and score when the underlying evaluations change. The static table keeps the primary comparison readable without requiring interactive controls.
