Invite them to an online poll inquiring about their hiring needs and frustrations. This will be a great way to validate that you're thinking right and to see how these quality leads themselves are describing the problems you are thinking about If you really want to crush it, reach out and make friends with some of the people on your list. From the material you collected in the polls, you can get in touch with each of them and ask for specifics, tell them how you are adressing the problems they are describing and so on. At this scale, don't think only of automatic emails. You are probably very eager to get to the stage when your email list is so huge that automated emails is the only way to go. But at this point, it isn't. Use that to your advantage.
