Dear :

I am delighted to inform you that we have just added a new line of [products] which incorporate a number of remarkable new features. I am sure they will appeal to your customers and become a bigger winner for you than the models of last year. I have enclosed a brochure with color photographs, product specifications and prices.

Please let me know if you want us to send you samples of this new line.

Sincerely yours,
