Online campaigns

I am a co-op student and my marketing project is to email garden clubs and offer them free samples of the garden products the company I work for makes. I need to know how to approach the clubs in my initial email so I want some insight into what they value most (ie free products, education, etc). This will help me choose my approach in order to get the largest response for my campaign. Any insight from gardeners/club members would be appreciated!

I am a co-op student and my marketing project is to email garden clubs and offer them free samples of the garden products the company I work for makes. The products are more expensive, electronic items so clubs will be given a choice of one of three products. I need to know how to approach the clubs in my initial email so I want some insight into what they value most (ie free products, education, etc). Should I just email and say “free product” or send them some research on a problem and how the products help solve it? Something else? This will help me choose my approach in order to get the largest response for my campaign. Any insight from gardeners/club members would be appreciated!
