My abstract strategy for making contact with the right people:

Try to imagine things from the perspective of the people you're trying to contact. What is their day-to-day, what are they sick and tired of? What will make your cold email stick out in that context? It's click-bait targeted at a specific person. Again, this is probably just one level above what the average person will do. But that already puts you ahead of most people. It gives you some chance of reaching the right person.
