Some email clients allow people to confirm receipt and to see whether an email has been read. To track email sent via Outlook, go to the Tools menu, and select Options. Under Email, select Email Options. Under Message Handling, select Tracking Options, and check Read Receipt.

If using Gmail, the browser requires an extension to be added in order to track whether a message has been read. Streak, which is designed as a customer relationship manager tool for businesses, allows a user not only to view when a person reads email but also to see the person's location on a map.
