Mailing plugin idea

Hi

I sugest a plugin that offers the opportunity to send emails to all my registered accounts. As of now the flynax software allows me to send emails but I do not know how many of them were opened or read. This is important to me because it allows me to know the feedback of my mailing campaign. It allows the opportunity to add many other functionalities like sending emails depending on the type of account among other benefits . Thanks

Doesnt this cover it http://www.flynax.com/plugins/massma...ewsletter.html, does most what you specify, like ability to choose account type to send too.

..but doesnt let you know who opened/viewed it, which would be an good feature to be added. Maybe also add ability to choose to view email online in browser url aswell.
