How does SuiteCRM know that someone viewed my campaign email?

Is this via a return receipt?

Hi,

The common way to do this (it looks like SuiteCRM does the same) is by adding a small image to the email. When the image is requested with a given id that email is marked as viewed. This means that only those clients that accept images are marked as viewed however.

Thanks,
Jim

Viewing the message source, there is a 1px x 1px image appended to the end.

Thanks
