How to send a LinkedIn message to several connections

There are a few different ways to send LinkedIn messages to a bunch of connections, but here is one which I like to use. It takes a bit of time because you will ‘tag’ your connections (in order to group them) but once you have that done, sending the message is only a two step process.
Note that LinkedIn limits the number of recipients to 50 so keep that in mind and also be sure to uncheck the box below the text area so that recipients can’t see each other’s contact info.
