Features
Lettium is a newsletter design tool. Design a newsletter on a canvas, draft with AI, review with your team, and export HTML.
Getting started
Create an account and open a file. A new artboard is the standard email frame, 600 pixels wide.
Canvas
Position and nest elements on an email-aware canvas. The artboard stays 600 pixels wide, and neighboring elements do not overlap.
AI
Describe the email in one sentence. Lettium drafts it on the artboard, and you refine every block.
Review
Pin a comment to the element you mean. The thread stays beside the design and out of the email you send.
Export
Send one test email, then download a ZIP, copy the HTML, or save it for a platform you already use.
