Everything you need to track emails

Checkmarks in Your Sent Folder

Gray single tick means tracked, blue double ticks means opened. Right in your Gmail sent folder, just like WhatsApp.

Desktop Notifications

Get instant desktop alerts the moment someone opens your email.

Tracking Dashboard

See all your tracked emails, open rates, and device info in one place.

Your Data Stays Yours

No email content is ever read or stored. We only save what's needed to show you open status. Nothing is shared with third parties.

How it works

1

Install the extension

Add DoubleTick to Chrome in one click. Sign in with Google to get started automatically.

2

Compose & send

Toggle tracking on next to the Send button. An invisible 1x1 pixel is embedded in your email.

3

Get notified

Gray tick = tracked. Blue double ticks = opened. Plus instant desktop notifications.

Built with privacy first

We only track what you ask us to track. Nothing more.

Only tracks emails you explicitly enable. Nothing else is touched.
No email content is read, stored, or transmitted. Ever.
Tracking data is stored securely and visible only to you.
No data is shared with third parties. Works entirely within Gmail.
