Email marketing

I am looking for a talented and experienced Freelancer to help with my email marketing campaign. The goal of the campaign is to promote a product or service. To achieve the highest impact, I'm looking for an email format and style that employs a combination of both text-based emails and HTML emails. I plan to send out emails on a monthly basis. I am looking for someone who can help construct attractive and effective email campaigns, as well as monitor and track the performance.
