Time for another “LinkedIn Secret”: Everybody in the chain can read every message of an introduction.
When you send an introduction request to someone via “Get introduced through a connection”, you always have to write two messages: one for the final recipient and one for your first degree contact.
Be aware that everybody who is “in the chain” can read all messages. In practice this means that your first degree contact can read your message to him and the final recipient, that the second degree contact can read your two messages and the message from your first degree contact to him and that the final recipient can read your two messages, the message from your first degree contact to your second degree contact and from the second degree contact to him.
So always be professional in the messages you send whether it is an introduction request from yourself or whether you forward a message from someone else.
I think it was Warren Buffet who said, “It takes a lifetime to build a reputation, but only a few seconds to destroy it.”
To your success !
