Read Tracking/ Read Receipts let you know if the email you’ve sent has been read or not and Canary lets you do just that.
1. On your Android app, Read Receipts can be enabled from Settings. Toggle ON Read Receipts via Canary > Settings > Composing > Read Receipts.
2. Check which of your emails have been read by clicking on Dashboard > Read Receipts.
3. You’ll be able to see the list of emails along with the time when they were read by the recipients.
