links in newsletter (auto add products/language?)

Hi all,

I would like to add links to my newsletter where people can click on a link to go straight to the website and have an item automatically added to the cart.
Something like:
Click here to add this item to your cart.

It seems to work with the coupon by using the following link string:
http://your.website.com/index.php?coupon=28122013

I would like to do the same with a product and also automatically have a language selected.

Can someone help?


Thanks

Anyone?

How to add a link in a newsletter to add a specific product straight in the cart?
