Not only just tracking as the original comment, but the ability for “reply” to be added to the “if/then” logic of a workflow. If I send a marketing campaign, I should be able to know, “Hey these people replied and these people didn’t.” Campaigns should be based around ACTUAL BEHAVIOR not time or non-discrete behavior. The options right now certainly aren’t based upon real, tangible behavior that’s centered around buying.
The current situation.
