Re: How to make a Product introduction letter
I don't think you will like my answer but the first thing to consider is changing your name. I don't want to think about horses as having anything to do with my food!
As for a product introduction letter, your own conpany's marketing department should be able to help you with that. They will know your products' differentiators and how they fit in your market sector.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
