Doubletick

DoubleTick — Simplest way to know exactly when your emails get opened.

Wondering if your email was read, ignored, or lost in spam? DoubleTick adds read receipts to Gmail so you get a clear signal the moment someone opens your message — whether they are on desktop or
mobile.

FEATURES

• Double checkmarks appear on opened emails right in your Sent folder — no guessing.
• Desktop notifications the moment a recipient reads your email.
• Open count, device type, and exact timing available in the popup dashboard.
• One-click toggle lets you track only the emails that matter. Everything else stays untouched.
• Zero impact on email deliverability. Your emails land in inboxes, not spam.

USE CASES

• Job applications — Find out if a recruiter actually opened your resume or if it is sitting unread. Follow up with confidence, not anxiety.
• Sales proposals and quotes — See which prospects are engaging with your pitch and which ones need a nudge. Time your follow-up perfectly.
• Invoices and billing — Confirm your client received the invoice before the due date passes. No more "I never got it" excuses.
• Outreach and cold email — Measure which subject lines get opens and which get ignored. Iterate fast, send smarter.

PRIVACY

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

Install it in seconds and never send an email into the void again.
