HTML Mailer Studio
Paste your hand-coded HTML email templates directly into Odoo Mass Mailing — with a live split-view preview, ACE code editor, and 100% native tracking, unsubscribe & A/B test compatibility.
Odoo Mass Mailing only provides a visual drag-and-drop builder. If your team uses external HTML email designers — Litmus Builder, MJML, Stripo, BeeFree, or hand-coded responsive templates — you have no way to paste raw HTML directly.
This creates real pain for marketing & development teams:
- Pixel-perfect designs get mangled — the drag-and-drop builder strips or rewrites your HTML structure
- No syntax highlighting — editing raw HTML in a plain textarea is error-prone and slow
- No live preview — you must save and send a test email to see how the layout renders
- MJML / Litmus exports unusable — you cannot paste compiled HTML from professional email tools
- Agency workflows blocked — designers hand off templates that cannot be loaded into Odoo
- Re-work every campaign — re-building branded templates from scratch inside the builder wastes hours
HTML Mailer Studio adds a dedicated "HTML Code" tab to every Mass Mailing record. Enable the toggle and a full ACE code editor (monokai theme, HTML syntax highlighting) opens beside a live iframe preview — side by side. Paste your template, see it render instantly, and save. Odoo's native body_html is synced automatically, so open tracking, click tracking, unsubscribe links, mailing lists, and A/B tests all continue to work exactly as before — zero configuration required.
- ACE Code Editor: Professional syntax-highlighted HTML editor with monokai theme, line numbers, and auto-indent
- Live Split-View Preview: Real-time iframe preview renders your HTML instantly as you type or paste
- HTML Mode Toggle: One-click switch to enable or disable HTML code mode per mailing — the visual editor tab remains untouched
- Paste & Clear Toolbar: One-click paste from clipboard and one-click clear — no keyboard shortcuts to memorise
- Isolated Preview: Styles render inside a sandboxed iframe — they never bleed into the Odoo backend UI
- 100% Native Tracking: Auto-syncs to
body_htmlon save so Odoo's open & click tracking works without any changes - Unsubscribe Compatible: Native Odoo unsubscribe link injection continues to work — no workarounds needed
- A/B Test Ready: Fully compatible with Odoo's built-in A/B testing feature — test HTML variants side by side
- Read-Only Safety: Editor is automatically locked in read-only mode when the mailing is in Sent or Sending state
- Zero Config: Install and go — no API keys, no external services, no additional settings
1. Email Marketing List View
Standard Odoo Email Marketing list — HTML Mailer Studio integrates seamlessly without changing anything you already know.
2. New Mailing — HTML Code Tab (Toggle OFF)
A new HTML Code tab appears before the Mail Body tab. While the toggle is off, a helpful placeholder guides the user — the visual editor is untouched.
3. Enable HTML Code Mode
Click the Use HTML Code toggle. The ACE editor initialises instantly — ready to accept your template.
4. Paste HTML — Live Split-View Preview
Paste your full HTML template on the left. The right pane renders a pixel-perfect live preview in real time — including gradients, custom fonts, and responsive layouts.
5. Editor Close-Up — Split Pane Detail
Monokai syntax highlighting on the left, clean rendered email preview on the right. The toolbar offers one-click Paste and Clear buttons.
6. Saved — Ready to Send
Click Save. The HTML is synced to Odoo's native body_html field. Send, schedule, or run an A/B test — all standard Odoo mailing features work as expected.
Installation & Configuration
- Install the Module: Install through Odoo Apps or copy to your addons path
- Dependencies: Requires only the
mass_mailingmodule (Email Marketing) - Restart & Update: Restart the Odoo server and update the app list
- No Additional Configuration: Works immediately after installation — no settings to configure
- Test: Open any Mass Mailing → click the HTML Code tab → enable the toggle → paste your HTML
Step 1: Create or Open a Mass Mailing
Go to Email Marketing → Mailings → New. Fill in the Subject and Recipients as usual.
Step 2: Open the HTML Code Tab
Click the HTML Code tab (first tab in the notebook, before Mail Body). A placeholder explains the feature.
Step 3: Enable HTML Code Mode
Toggle Use HTML Code on. The ACE editor and live preview pane appear instantly. The tab now shows both panes side by side.
Step 4: Paste Your HTML Template
Click the Paste button in the toolbar (or Ctrl+V in the editor). Your full HTML — including inline CSS, images, and email-specific tags — is loaded. The preview updates immediately.
Step 5: Edit and Preview in Real Time
Make any changes directly in the editor. The preview pane reflects every keystroke instantly — no save required.
Step 6: Save and Send
Click Save. The HTML is automatically written to body_html. Use the standard Send, Schedule, or Test buttons as normal.
Odoo adds tracking pixels, click-tracking wrappers, and unsubscribe links automatically.
Pro Tip — Compatible HTML Email Tools
MJML: Compile your .mjml template and paste the resulting HTML — responsive email code works perfectly
Litmus Builder: Export HTML from Litmus and paste directly into the editor
Stripo / BeeFree: Export as HTML and paste — all inline styles preserved
Hand-coded templates: Any valid HTML with inline CSS renders correctly in the preview
Visual Editor vs HTML Code Mode
The Mail Body tab and its drag-and-drop builder remain fully available. HTML Code Mode and the visual builder are independent — switch between them at any time before sending. When HTML Code Mode is enabled, the body_html is set from your raw HTML. When disabled, the visual editor controls the content.
Marketing Teams
Use agency-designed HTML email templates without re-building them inside Odoo's visual editor. Send branded campaigns exactly as designed.
Digital Agencies
Deliver pixel-perfect email designs to Odoo clients without compromise. Paste compiled MJML or Litmus exports directly into the client's Odoo instance.
E-Commerce Stores
Send high-converting promotional emails with custom HTML layouts — product grids, countdown timers, promo codes — all rendered precisely in every inbox.
Odoo Developers
Test and iterate on transactional or marketing email HTML directly inside Odoo — live preview eliminates the send-and-check cycle during development.
Newsletter Publishers
Load monthly newsletter templates created in Stripo or BeeFree and send them to mailing lists with Odoo's native unsubscribe management.
A/B Test Power Users
Create multiple mailing variants with different HTML layouts and run Odoo's native A/B testing — let the data decide which design wins.
Design Freedom
Your email looks exactly as designed — no layout mangling, no stripped CSS, no forced columns.
Hours Saved Per Campaign
Paste once and send — no re-building templates in the visual editor for every mailing.
Zero Tracking Breakage
Open rates, click rates, and unsubscribes work identically to Odoo's built-in email builder — no custom tracking code needed.
Instant Visual Confidence
Live preview eliminates the send-a-test-email cycle. See your email before clicking Send.
