Has anyone had success or failure with standardizing email subject lines of the messages being sent from CSM's to end users? We have a blend of automated tech touches and personal touches, and I'm just wondering if we can improve response rates if we direct users more through the subject lines. My thought was:
Realync [Info] Feature Release Updates
Realync [Response Requested] How to improve x
Realync [Action Required] Login Instructions Enclosed
The topics of my examples above can be improved, but I'm specifically asking if anyone has tried including the [Info], [Response Requested], [Action Required], and had luck? Or if it bombed and I should avoid 
Thanks!
