I don’t know if you use freelance writers for <name of publication>, but if you do I would like to offer you my services. More to the point, an article I’ve written called <article title>. It’s about <brief summary of your article>, and I think it would be perfect for your e-zine. Please let me know if you would be interested in seeing the piece. Also, please e-mail me your writer’s guidelines and any other information you feel would be helpful. Thanks for your time, and I hope we can work together.
