I want to send a *personal* status update to most of my LinkedIn contacts (~1300) comprised mostly of C-level decision makers. I don't want it to be an immutable template because with most of them I have some personal connection and wish to ask them something along the lines of "How is A...B...C going".
I've searched for tools for this quest but couldn't find anything suitable. Also it seems that LinkedIn no longer supports bulk messaging to 50 people (the checkbox in connections page is missing) :/
Do you know some tools or techniques that can aid such activity?
