The emails are great Travis, not much more to add to them.
My only thought is that you want to vary your messaging to a certain extent.
Humans are pattern recognition machines. If I don’t response to the first 3 short, sharp emails, I’m going to bias to not respond to the 4th.
Mix things up a little. Try and break the prospects pattern recognition system so they have to read the email rather than making assumptions about it.
Go short for the first few emails and then do something completely out of the blue. Then back to short and legible.
Also, you’ve been working on these emails for a couple of weeks. Have you started sending them?
