Unless you have specifically asked us to contact your 1st level connections that fit your targeting we will not be messaging your 1st level connections. We will be sending connection requests to people who fit your targeting and sending messages to those new 1st level connections. Additionally, we will be sending messages to 2nd and 3rd level connections that fit your targeting. By growing your 1st level connections we will also have more 2nd and 3rd level connections that we can message.
