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 structure, spacing, and CTA rendering hold up in Gmail web and mobile views. |
| Outlook Desktop (Windows) | Partial | Multiple logo columns can tighten slightly in Outlook desktop. |
| Apple Mail (macOS + iOS) | Tested | No additional notes. |
| Yahoo Mail | Tested | No additional notes. |
Related blocks
These components are closely related by category or usage pattern and are useful when assembling a full email flow.
Content Blocks
Three-column metrics block for product proof, launch stats, or engineering credibility moments.
Content Blocks
Customer quote section for social proof in marketing and nurture emails.
Content Blocks
Compact app-download section with platform badges for onboarding, support, and activation emails.
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.
