Luxa Mailbox – Read and send email right inside wp-admin.

Features

  • Connect one mailbox via IMAP (receive) and SMTP (send) — works with Gmail, Google Workspace, Outlook/Microsoft 365, and the mail account that comes with most cPanel/DirectAdmin hosting. SSL and TLS supported.
  • Gmail-style three-column layout: folders, message list, reading pane.
  • Browse every folder your mail server has, with pagination and full-text search.
  • Compose new messages and reply (with the original quoted automatically), including Cc/Bcc and file attachments.
  • Delete messages and mark them read/unread, right from WordPress.
  • Mail passwords are encrypted before being stored in the database.
  • One-click Test connection for both IMAP and SMTP, so you know your settings are correct before you rely on them.
  • Clean, native wp-admin styling — no heavy JavaScript framework, no dependency on any third-party service other than your own mail server.
  • Built to be extended: Luxa Mailbox Pro adds multiple mailboxes, message assignment and status tracking, internal team notes, canned responses, and an add-ons ecosystem on top of this same free foundation.
