Here is a very good blog post by Allie Janoch about 2 cold emails she sent: the first one got ignored, the second one led to the funding of her startup.
The second email explains what the company is about (surprisingly not all emails do), a tangible description of the problem it solves, meaningful metrics, an explanation why this is a fit for this VC, links for more detailed info, the right length of text, not too generic, not too much, good typography and paragraph spacing.
