Auto daily email to customer oscommerce

I'm looking for a solution to keep oscommerce admin work to a minimum. I would like the store to automatically send an email to our customers each morning. The email contents should reflect the customers order status, for example: customer orders status is A = the store should send template each day and rotate between template A1 ~ A2 so not the same email every day customer orders status is B = the store should send template each day and rotate between template B1 ~ B2 so not the same email every day The email template should be able to automatically rotate between different templates so the customer dont receive the same identicle email each day and things like choose how many days to send email, who many days to send email, each day, every two days.... Is customers order is already shipped then an email must not be sent auto since it will already have been sent manually when the order was shipped.
