Luxa Mailbox — User Guide

Last updated on August 3, 2026 · 7 min read

This guide covers everyday use of Luxa Mailbox: the free plugin, Luxa Mailbox Pro, and any Pro add-on. Sections are clearly labeled Free, Pro, or Add-on — if a heading has no label, it applies to everyone.

For installing the plugin and activating a license, see the Installation & License Setup Guide instead. This guide assumes you’re already up and running.

1. The Mailbox screen

Go to Mailbox in your WordPress admin sidebar. This is where you read and send email — everything here talks directly to your real mail server over IMAP (for reading) and SMTP (for sending); nothing is copied into WordPress.

The screen has three columns:

  • Left — Folders. Every folder your mail server has: Inbox, Sent, Drafts, Trash, and any custom folders/labels. Click a folder to view it.
  • Middle — Message list. Sender, subject, and date for the selected folder. Unread messages are bold. Use the search box above the list to search the current folder (subject and sender).
  • Right — Reading pane. Click any message in the list to read it here, including attachments.

Composing a new message: click Compose in the sidebar. Fill in To (and Cc/Bcc if needed), a subject, your message, and attach files if needed, then click Send.

Replying: open a message and click Reply. The original message is quoted below your reply, and the subject/recipient are filled in automatically.

Deleting a message: open it and click Delete. This moves the message to your mail server’s Trash folder (or deletes it permanently, depending on your mail server’s own settings) — it does not just hide it in WordPress.

Attachments: when composing, click the paperclip icon to attach one or more files. When reading a message with attachments, click any attachment to download it.


2. Settings (Free — single account)

Go to Mailbox → Settings. This is where you enter the connection details for your mailbox:

  • IMAP (for receiving): host, port, encryption (SSL/TLS/none), username, password.
  • SMTP (for sending): the same fields, for your outgoing mail server. Many providers use the same host for both, but not all — a Gmail account’s IMAP is imap.gmail.com while its SMTP is smtp.gmail.com, for example.

Click Test IMAP connection / Test SMTP connection before saving for real — this confirms your details work without needing to send a real message first.

Your mail password is encrypted before it’s stored in the WordPress database. Nobody with access to your site’s database can read it back as plain text.

Free vs. Pro: the free plugin manages exactly one mailbox. If you need several (e.g. support@, sales@, billing@), that’s what Mail Accounts in Pro is for — see the Pro section below.


3. Mail Accounts — Pro

Go to Mail Accounts in the sidebar. This is where you manage every mailbox connected to your site — as many as you like, each with its own IMAP/SMTP connection.

  • Add Account — same IMAP/SMTP fields as the free Settings screen, plus a Label (a short name to tell accounts apart, e.g. “Support” or “Sales”) shown in the account switcher on the Mailbox screen.
  • Set as default — the account shown on the Mailbox screen the first time you open it in a session.
  • Test connection — available once an account is saved; verifies its IMAP/SMTP details the same way the free Settings screen does.
  • Delete — removes the account. At least one account must always exist and be marked default.

Switching between mailboxes

Once you have two or more accounts, a dropdown appears at the top of the Mailbox screen’s sidebar. Pick an account to switch the whole screen — folders, message list, and reading pane — to that mailbox. Everything you do afterwards (reading, replying, assigning, adding notes) applies to whichever account is currently selected.


4. Assign + Status — Pro

When you open a message, a small bar appears below the sender/subject with two controls:

  • Status — Open, Pending, or Resolved. Use this to track where a conversation stands, especially useful for a shared support inbox.
  • Assign to — hand a message to a specific teammate. Anyone with access to the Mailbox screen can be assigned.

Both are visible at a glance from the message list too: a small colored badge shows the status, and an avatar-style initial shows who a message is assigned to, so your team can scan a folder and immediately see what’s outstanding and who owns it.

Status and assignment are per mailbox — if you’re managing several accounts, switching accounts shows that account’s own assignments, not a mix of everything.


5. Internal Notes — Pro

Below the Assign + Status bar, every message has its own Internal Notes thread — a place for your team to leave context that’s never sent to the customer (“Called them back, waiting on a callback Tuesday”, “Escalated to billing team”, etc.).

  • Type a note and click Add note. It appears immediately, with your name and the time.
  • You can delete your own notes (click the × next to a note). For accountability, nobody — not even a site administrator — can delete a note someone else wrote.

6. Canned Responses — Pro

For answers you type often (a refund policy, a shipping FAQ, a standard greeting), save them once and reuse them instead of retyping.

Managing your responses: go to Canned Responses in the sidebar. Click Add Canned Response, give it a short title (shown in the dropdown when composing) and the response text, then save. Edit or delete existing ones from the same screen at any time.

Using a response: open Compose or Reply, and look for the Insert response… dropdown in the compose window’s toolbar. Pick a response and its text is inserted at your cursor’s position — edit it further before sending if needed.


7. Add-ons — Pro

Go to Add-ons in the sidebar. This is a catalog of optional, separately-licensed plugins that extend Luxa Mailbox Pro with extra features beyond what’s built in.

Each add-on card shows its name, description, and price, and moves through the same four states:

  1. Unlock — enter the license key you received when purchasing the add-on.
  2. Install Now — downloads and installs the add-on’s plugin files (the same mechanism WordPress itself uses to install any plugin).
  3. Activate — turns the add-on on.
  4. Active — the add-on is running; a Deactivate button appears if you ever need to turn it off (and Uninstall, once deactivated, if you want to remove it entirely).

If the catalog is empty, there are currently no add-ons available for your version of Luxa Mailbox Pro — check back later, or see luxapress.com for what’s currently offered.

Each add-on has its own license key, separate from your Luxa Mailbox Pro key. An add-on always requires an active Pro license to function, even if the add-on’s own key is valid — see the Installation & License Setup Guide for how the two relate.


8. Modules — Pro

Go to Modules in the sidebar. Unlike add-ons, modules are features already included inside Luxa Mailbox Pro — nothing to install or license separately, just an on/off switch for optional behavior. Some modules are marked Required and can’t be turned off, because they’re part of how Pro itself works.

If a future Pro update ships an optional bundled feature you don’t need, this is where you’d turn it off.
