MailTracker by Mailsumo

Know exactly when your emails are opened. Real-time read receipts for Gmail.

MailTracker tells you the moment your emails are opened, right inside Gmail. A single grey check means your email was sent. A double blue check appears the instant it's read. No new app to learn: the status shows up on your Gmail thread list and inside each conversation. WHY MAILTRACKER • Accurate opens: we filter out Gmail's image pre-fetch, Apple Mail Privacy Protection, and corporate security scanners, so you don't get a "read receipt" the second you hit send. • Your own opens never count: viewing your Sent mail won't trigger a false open. • Real-time: desktop notifications and live status updates the moment an email is opened. • Reports: best send times, open rates, and time-to-first-open across your email. • Fast: a lightweight footprint that doesn't slow Gmail down. FREE FOREVER Track up to 20 emails a month, with full open history, notifications, and email alerts, all free. PREMIUM Unlimited tracking, link click tracking, follow-up reminders, per-recipient attribution, CSV export, scheduled-send tracking, and no signature. PART OF MAILSUMO MailTracker is one of four Mailsumo tools sharing a single account: Email Extractor, Email Finder, Email Tracker and the Email Verifier add-on. One login, one invoice, and the option of a bundle if you use more than one. PRIVACY We store subject lines and recipients to power your reports, never the body of your emails.
