About this extension

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

Read the publisher’s full description

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. Recipient IP addresses are anonymized. See our privacy policy at https://mailsumo.io/privacy. Not affiliated with Google. Gmail is a trademark of Google LLC.
