Let me say it now, if I haven't made it clear before:
Email is a terrible prospecting tool...don't do it!
You know what makes a great prospecting tool? Old Fashioned Direct Mail. People still respond pretty much like they always have to traditional direct mail....which is usually not too great. That doesn't mean that it shouldn't be part of your prospecting arsenal.
The difference now is that you have a way to measure it. If you can measure, you can improve.
Like all good marketing, test and consider what the goal is. I find that driving people to a custom landing page can offer dramatic results. Make a compelling case to visit a specific webpage and on that page drive them to 'conversion' which should be an opt in to learn more about you.
Postcards, Letters, Handwritten notes all work wonders. Just put some effort into versions and testing...and make sure your landing page has the clear purpose of getting that opt in.....you don't want to waste that time and effort (and expense) for a one time visit. You are looking to get Married :-)
Next we will talk about the phone....
