Use case

Email marketing strategy

Strategy improves when you measure opens on real conversations — not just newsletter dashboards. Mail Track brings that signal to Gmail.

Strategy grounded in opens

Even small lists teach you what works when every send has a read receipt.

Test subjects on real segments

Try two subject lines with similar contacts and compare first-open rates.

Time sends with data

Learn when your audience actually opens — mornings, lunch, or evenings.

Iterate without a ESP

Perfect for founders and creators who market from Gmail, not Mailchimp.

In Gmail

Open metrics on personal outreach
