As I was busy going through some of my old books, I found this book by Seth Godin called "Permission Marketing" there might be updated versions of this but a couple of good points he made stood out.

Most of you probably know this already but interesting for those who don't.

First you offer your prospect an incentive to give you permission to market to them.

Then you teach them about your product or service, you also have to reinforce the incentive for them to keep on listening to you.

Offer additional incentives to get more permission from your prospect and then over time use the permission to change your prospect into a customer.

Keep the rules of dating in mind and you could be very successful in engaging with your potential prospects.
