Our analysis
AI-assistedWP Mailster is a WordPress plugin designed for group communication via email. It allows users to participate in discussions without needing to log into a website, functioning similarly to mailing list software like Mailman or Listserv. Emails sent to a central address are distributed to all group members, and replies are forwarded back to the list, enabling true two-way communication.
The plugin supports any POP3/IMAP email account and allows for easy management of recipients through the WordPress admin area. Users can subscribe and unsubscribe via website widgets, and groups can be organised for more efficient communication. This plugin is suitable for those looking to facilitate email discussions among groups without the need for a dedicated platform.
Best for: This plugin is best for websites that need to facilitate group discussions through email.

From the developer
brandtoss's own description of WP Mailster, lightly tidied.
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.
