We need an interface to send out our newsletter - built on our own servers.
1) Check off a list (or query) to use for sending. This will hit our 'user' table and define the email addresses to send it to
2) A text box for HTML. We already have the newsletter auto-built each week and can just paste the HTML into it.
3) Sends one email per user - not all users in the BCC field. Important.
4) An unsubscribe page to udpate a field on the user table (verify email address/password first)
*Bonus) Any tracking ideas for determining how many times the newsletter is opened is a bonus. We can track clicks back to the site with other variables, so that isn't needed - but being able to track the open % would be nice.
