Rendering screenshot
Preview frame reflects current component rendering and real spacing proportions for production email QA.
Live preview
This preview is rendered from compiled HTML output so you can inspect the actual email structure, not a static mock-up.
Client support
Rendering support notes across major email clients.
| Client | Status | Notes |
|---|---|---|
| Gmail (Web + Mobile) | Tested | Primary spacing, stack order, and CTA rendering hold up in Gmail web and mobile views. |
| Outlook Desktop (Windows) | Partial | Image-and-copy split layouts remain dependable, though Outlook can stack the columns earlier than webmail. |
| Apple Mail (macOS + iOS) | Tested | No additional notes. |
| Yahoo Mail | Tested | No additional notes. |
Used in layouts
These layout pages include this component in context, with block order, message structure, and QA guidance alongside the rendered email.
Related blocks
These components are closely related by category or usage pattern and are useful when assembling a full email flow.
Heroes
Image-led hero with centred framing and left-aligned body copy for richer launch or announcement sends.
Heroes
Centred hero section with label, headline, support copy, image, and primary CTA.
Heroes
Split hero with image on the left and message stack on the right.
Source code
The source and compiled HTML shown below map directly to the rendered preview above. This keeps preview, MJML, and HTML handoff output aligned.
Snippet assembly: place this block inside the same <mj-body> as your other snippets, then stack sections in send order.
Component block only. Use this when assembling an email from multiple reusable sections inside a project that already includes the shared MJML classes.
