Can you share a sample of the cold emails you send looking for sponsors for your newsletter, blog etc?

Hi guys,

I just launched FilmWaiver, a free chrome extension app that automatically detects and applies discount codes for film festival submissions. It works exclusively for Filmfreeway for now.

I have some ideas as to how to begin generating revenue by talking to film festival organizers to coming on board as sponsors but I am not sure the type of data to share with them or generally speaking if there is a cold email template for seeking sponsors.

For those that run successful newsletters, blogs, etc, how do you get your sponsors? sharing an example of the cold email you send seeking out these sponsors will be very valuable.
