With version 4.53.10 of Email Marketing we have added the capability to share message reports. This is a great enhancement to our reporting capabilites as you can now share all statistical data with anyone without the need to setup a username just for report viewing. You can find this feature by going to the message archive, selecting a mailing, and clicking on share report. Below you will find some screenshots of how sharing works.
