Your newsletter design tool.
Tweak every detail.
Draft a layout with AI, refine it on an email-aware canvas.
Lettium is a newsletter design tool. Design a newsletter on a canvas, draft the layout with AI, and export HTML for the platform you already use.
Stop rebuilding the design in the email builder.
You compose in one tool, then lose spacing, hierarchy, and layout when you paste blocks into a rigid template editor.
Your layout. Not the builder’s.
Create the composition you have in mind. Position, nest, and adjust elements directly on the canvas, with structure designed for email rather than locked templates.
From one sentence to a finished layout.
Describe the email you have in mind. Lettium drafts it on your artboard, with every block placed inside safe email rules and ready for you to refine.
Keep the feedback beside the design.
Discuss the exact element that needs attention, with comments pinned to the newsletter. Give your team a shared place to review instead of another set of screenshots to reconcile.
Built for email, not just the canvas.
Work within an email-aware structure, export table-based HTML, and send a test email before you hand the design over. Download a ZIP, copy the HTML, or save it for a platform you already use.
