“This is to thank you for the outstanding service you rendered in connection with my recent purchase of life insurance.
Your unique service of Prequalification was especially helpful. I was under a time pressure, and the fact that you Prequalified me allowed me to make my decision quickly without having to wait weeks for an insurance company.
I would remind you also that I told you in the beginning of the process that I have been dealing with a highly professional agent in South Carolina for 50 years and would probably place the business with him unless it was especially worth my while to change. Not only was your Prequalification much faster than waiting for him, but the rate you got for me was considerably under that which he obtained.
You can be assured I will most certainly contact you for any future insurance needs I might have.”
