More effective:
Hi this is Ashley Smith (ALWAYS use a last name, it builds more trust) with Loozeeanna Health Whatever. We've recently released a special report that reveals the 3 biggest mistakes that business owners make when buying health insurance...and we'd like to email you a free copy...what is your email address?
Write a report (keep it educational, not salesy), make a pdf, email it to them.
Keep a file of the the names/numbers/addresses. Call 'em back to see if they have any questions on the material. Keep drippin' on 'em (email, postcard - just as long as it's CONSISTENT.
When the time is right, they'll call you.
Good luck!
What if they don't have any questions on the material. I assume you have additional follow up questions? Can you explain your process a little more deeply?
