Canary Mail's Read tracking feature lets you know if the email you’ve sent has been read or not.
Read Tracking on your macOS device
By default Read receipt is enabled in Canary Mail.
Note: Once your email has been read, a notification will be sent to you and Canary Mail blocks all tracking services.
Check Read Receipts:
In your inbox, tap on the ‘read receipt’ icon to see which emails have been read. All read emails will be displayed in your Read Activity.
