We are Exchange 2013 on premises ONLY, we may go 365 but not at this time. Our marketing team sends a weekly email globally to internal users only. They're requesting metrics around at least a true read status for the email. Did they read it, delete it immediately etc...
Blue sky option would be to be able to tell difference between an email opened in full outlook client and webmail or smartphone. We have tried various scripts found online with no success.
What are you using for this purpose? If you went with a third party app to deliver, please let us know which. Would listserv option be a better solution?
Thanks in advance!!!
