How WP Mailster works
Show full descriptionShow less
True two-way group communication over email
WP Mailster allows your users to be part of a group and communicate by email without having to log into a website.
Similar to programs like Mailman or Listserv this plugin allows you to run a discussion mailing list.
That means that every email sent to a central email address is forwarded to the rest of the members of the list.
When members reply to such list emails WP Mailster again forwards them to the other list recipients.
Unlike newsletter plugins this allows true two-way communication via email.
