I am looking for an email marketing service, because I don't know of any software that can track whether an email has been read or not.

Basically, the service should allow me the following:

- Create, send html-based newsletters to subscribers
- Having tracking capability (whether or not the user clicks on a link in the email)
- Allow for creation of subscription form (i.e. be able to create form with name, address, city, state, etc etc.)

Any good services for this that are less than $15/month ?
