The Mailing Group Listserv plugin allows you to run a Mailing Group, also known as a Listserv, right from your WordPress website. You can sign up your users, friends, family etc, directly from your WordPress administration area, and they can then all exchange emails via their favourite email software, no need to login to wordpress dashboard. It has very easy to use intuitive interface and advanced debugging functions. This is NOT a one-way Announcement list where only YOU can email everyone else. Its a Two-Way mailing group just like Yahoo Groups, Google Groups etc (provides most functions of those groups but not all). It can be used as a partial alternative to php List and mailman. Its a wonderful wordpress group plugin to help you and your groups stay connected! – Premium version includes message moderation and archives. 
Premium version offers Email message archives where so you can see all messages sent to mailing group in these archives. Users can also see archives of their groups. Pro version also supports email moderation.

Not only the plugin works wonderfully, the support is incredibly fast and helpful. Had an issue that wasn’t even directly caused by the plugin, support promptly helped me and within a few hours everything started working again.
