Email Marketing HTML Generator: Test-Send Like Canva

Email marketing has a problem no other design output has: a layout that looks perfect in the browser can fall apart the moment it lands in a real inbox. Gmail, Outlook and Apple Mail each render HTML differently — many don't support modern CSS like flexbox or grid, some strip long content, others block images by default. A preview inside your editor is never proof of how the email actually looks once it's delivered. MarkupGen closes that gap with two connected features: generating real, inbox-ready email HTML, and sending an actual test email so you can check it the way it will really be seen.

Why email needs a different kind of preview

A webpage only has to work in browsers, which mostly agree on how to render modern CSS. Email clients don't. The safest, most compatible way to build an email is still table-based layout with inline styles — the same approach email developers have relied on for years, because it's the one rendering engine across Gmail, Outlook and the rest can be trusted to handle consistently. That's a very different output than a landing page or app screen, and it needs to be treated as its own format from the start.

From Figma frame to inbox-ready HTML

1. Export from Figma. Select the email design frame in the Figma plugin. Structure, copy and images go straight to your MarkupGen workspace.
2. Generate as Email HTML. Choose the "Email HTML" output mode, and AI builds a table-based layout with inline CSS — the format email clients actually render correctly, instead of the flexbox/grid markup used for web pages.
3. Refine in the editor. Swap headlines, adjust copy, and assign images directly in the live preview, so what you see is what will ship.
4. Send a real test. Click "Send test email" to check the result in an actual inbox before sending the campaign.

Test-send: check a real inbox before you launch

This is the part that mirrors Canva's "Send test email" feature, and it's what actually catches the bugs a browser preview can't:

• One click, real inbox. The exact HTML you just generated — not a simplified preview — gets sent to an email address of your choice, pre-filled with your own so you can check instantly.
• Blocked when content isn't ready. If any text or image placeholder in the design is still unassigned, the send is blocked with a clear message, so you never test-send an unfinished email by mistake.
• Honest about delivery. If the environment isn't yet connected to a real email-sending service, the system logs the send instead of silently pretending it worked, and tells you so — no false confidence that a test actually reached an inbox.

Opening the result in Gmail or Outlook is the only reliable way to catch what a browser preview hides: broken images from bad links, tables that shift on Outlook's Word-based rendering engine, fonts falling back incorrectly, or content getting clipped by an email client's size limits.

Who this is for

Marketers can go from a Figma email design to a verified, send-ready campaign without opening a separate email testing tool. Designers get instant confirmation their layout survives real-world rendering. And nobody has to hand off a "looks fine in the browser" file and hope for the best.

If you have an email campaign waiting in Figma, you can start for free and see it become real, tested HTML in minutes — no credit card required.
