The simple and easy way to connect your contacts.
"You should meet ..."
"I know the perfect person ..."
"You should meet my business partner ..."
"Let me introduce you to my dentist ..."
"My friend rock climbs also. You should meet her ..."
"You guys should connect ..."
Stop writing long intro emails and make the connection in a few steps. Remove that awkward step where your contacts have to put you on BCC: and let the connection move forward gracefully.
