Ask HN: Please suggest a good humane template for introducing my product

Very soon I will start sending (cold) emails to potential clients to introduce my product.<p>I was looking for templates, but they all sound very mechanical and business-ish.<p>I would have love to make this template myself, so it properly expresses my intention, but I feel like my ability of expression in writing is a bit limited.<p>Does anyone know of a good template (which speaks as one human to another) that I can use for email introductions of my product ?<p>It probably does not matter, but the product is a social/peer learning product for software organizations.<p>Thanks for your help.
