I put the pink copies on my desk for the first week until I make the connection. once I make the connection usually via three way email I keep it on my desk until a meeting is set. If no one replies to my first introduction email I will usually follow up with my client first to keep them warm as a lead for my team member. It's been my experience that a connection doesn't happen more often because of my client not replying versus my team member. Once the meeting is set I put the pink copies in a box in my desk drawer.
