Read receipts for Gmail
Checkmate adds a ✓ to emails you have sent and a ✓✓ once the recipient has read them. The ticks appear in your Gmail list rows and in the opened email.
How it works
- ✓ means the email was sent. ✓✓ means it was read.
- Works in Chrome and Edge.
- Free. Free emails carry a small "Sent with Checkmate ✓✓" footer; a subscription removes it.
- Addresses and email content stay in your browser. See the privacy policy.
