Currently ACT does not recognize an incoming "Read Receipt" email in Outlook as a valid email. Consequently it will not add it to the history for a particular contact. I do work where I send out RFP's to vendors followed by extensive communications with those vendors. I track read receipts to ensure that what I sent out got to the reader.If I don't get the read receipt I need to follow-up manually by phone to ensure it did get through (because some vendors turn off read receipts). I was really expecting that ACT would assist me in tracking this.
At the very least - ACT should recognize read receipts and add them to contact history
Even better - optionally automatically link the read receipt to my outgoing email and allow me to display it as another column in the history tab - that would make it very easy to identify that I had a read receipt and for which email it was associated. (maybe a colored flag - green for read-receipt received, yellow for too early to tell and Red for no receipt received - user configurable of course). I'm assuming here of course that there is some uniquely identifiable identifier in an email and its associated read-receipts that would them to be linked.
And then - give me reporting options to identify emails where I asked for a read receipt but didn't receive one - this lets me manually follow up to ensure the reader did or didn't receive my email.
