See how many times an email has been read

First, make sure "Email open tracking" box is checked on your Mailpanion settings page.

You can then see the Mailpanion email tracking indicators in your Gmail sent folder. The green indicator will be either a hollow or a solid circle.

Hollow circles mean that you email recipients have not read your email, but the email is tracked.

Solid circles mean your email recipients have read your emails at least once. Hover your mouse over the solid circles, you will see how many times your emails have been opened. If you click on a solid green circle, you will see detailed email open history as well as a graphic representation.

If there is no circle, then the email is not tracked, which could be due to several reasons.
