How can I contact people in Mexico using the internet?

I have a product that I want to promote in Mexico. I do not want to travel there. How can I use the internet to put my product in front of people who live in Mexico. Is there a site, tool, other, etc.? All I can come up with is looking for people here in the US that look the part and targeting them. But I also want people who live in Mexico and need at least an e-mail address to start promoting my product to them. How can I do that?
