An option to disable open and click tracking on a sent email / email in the "sent box" of an outlook add-in user would be nice to have. This would avoid a lot of confusion on the part of the sales team and would help with cleaner reporting.
I have our inside sales team using the Marketo for Outlook Plug-In. I also have Marketo set up to send them alerts if a lead opens or clicks one of these emails.
One concern they have is that they are triggering "false positives" when opening these emails in their sent folder in Outlook. Usually in order to use the message to "ping" that lead or contact in a follow up, or to copy content to use in another email.
A big thanks to Elliot Low for suggesting I submit this as an idea.
