*Use the word “with” instead of “to.” It sounds more positive. You want to talk “with” the person, not give them a “talking to.” It’s a subtle difference, yet it keeps the message positive.
Get to why you’re calling. Did you have a question you couldn’t find the answer to online? Are you inquiring about future business? Are you weighing your options about a purchase between a few different companies? State it clearly so the recipient of the call knows how to proceed.

A relatively unprofessional one — like mine, for instance — does the opposite: It encourages prospects, recruiters, and potential connections to run in the other direction.
“Hello ____. This is _____ again, calling from ______. I ran across some information on a client who made dozens of offers on houses before someone finally accepted one of them. We learned a lot from the experienced and I successfully used the findings to help other homebuyers make bids that were accepted early in the house hunting process. I thought I would share it with you in hopes of saving you time and making it easier for you to purchase the home of your dreams. I’ll email you the information. Give me a call if you would like to review it together. Thank you.”
