DoubleTick

Know when it's opened. Email read receipts for Gmail.

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.
