You can use an introduction to contact 2nd-degree connections through connections you have in common. You can request an introduction, and then your connection can start a message addressed to you and the desired recipient. Once the recipient accepts the introduction, you can exchange information directly.
Note: You won't become 1st- degree connections unless one of you sends an invitation to connect and the request is accepted. We recommend you only connect with those you know and trust.
To contact any LinkedIn member directly without an introduction, send an InMail.
