What is the best way to introduce software product by email?

[Vladimir]

A friend of mine who works in software company is about to introduce new innovative software. I want to help him with the promotion by emails, because I have friends that might be interested in this new product.

Of course, the software company will pay professionals for this service, but I'm personally involved. I need a template of email that will briefly introduce the software, and after the intro I plan to attach a file with presentation of the product.

So I need to grab their attention with short copy, so they are interested enough to check the presentation. I searched the web, but the outcome was long copies that looks like spam.

I just want catchy intro that will grab their attention. I have never wrote business emails before, and I have no idea of the needed format or etiquette.. And English is not my native language..

Thanks in advance!
