How can I enable read tracking for all emails?
To enable read tracking in all your sent emails, open your settings and check the Track reads checkbox.
NoteIf you send yourself a test email to try out the functionality, Missive will not show that you read your own email if you do so in Missive itself. You will need to open your email in a different app, like Gmail, Outlook, etc.
You can read more about read tracking in Missive on this page.
