Hi,

I decided to help a charitable organization in my community to help them raise funds for a good cause (saving Tigers from extinction).

I thought that:
1. ) I'd do some good
2.) I have a chance to practise my copywriting and marketing skills

So, now I'm in charge of writing a sales letter that will be sent out to 10,000 people. And I just realized how hard this was since the normal rules of "benefits", "testimonials", "scarcity" etc. aren't really the same here as of when you're selling a product. Or am I wrong?

What I'm really after is examples of sales letters that has been written for charitable causes and that is after donations from regular, working people.

Do you have any examples or can point me in the right direction?
