Seen - Invisible Email Tracker for Gmail

The truly free, invisible, and privacy-first email tracking tool for Gmail. Know exactly when your emails are read without annoying "Sent with..." signatures.

Seen is designed for professionals who value privacy, speed, and discretion. We believe email tracking should serve you, not advertise us.

Why Choose Seen?

➤ 100% Invisible Tracking We strictly do not add "Sent with..." signatures to your emails. Your recipients will never know they are being tracked. Professionalism comes first.

➤ No False Positives (Smart Filtering) Most trackers count your own views as "opens". Seen's intelligent blocking technology ensures that when you open your sent folder, it doesn't trigger a tracking event. We only notify you when they read it.
