## What is Lettium?

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. You design on a canvas, start from one sentence when you want, review with your team on the same artboard, and export table-based HTML for a platform you already use.

## How do I design a newsletter?

Place the layout on the canvas, nest the sections, and hand off table-based HTML. You do not rebuild it in a block editor to start.

## What is a newsletter design tool?

Lettium is newsletter design software you open in the browser. You design the email newsletter on a canvas, then hand off table-based HTML for a platform you already use.

## Can I design a newsletter with AI?

Yes. Describe the email in one sentence and Lettium drafts the layout inside safe email rules. You can revise that draft. Tidy changes spacing and type scale without rewriting the copy.

## How does AI design work?

You describe the email in one sentence. Lettium drafts it on the artboard, with every block placed inside safe email rules and ready for you to refine.

## How do teams review a newsletter?

Discuss the exact element that needs attention, with comments pinned to the newsletter. Threads stay beside the design instead of in the email you send.

## What happens when the design leaves the canvas?

The layout stays an email-aware structure and exports to table-based HTML. Send a test email, then download a ZIP, copy the HTML, or save it for a platform you already use. A test send is one message, not a preview of every inbox.

## Where can you export an email?

Download a ZIP, copy the HTML, or save a template or unsent draft in Mailchimp, HubSpot, Klaviyo, SendGrid, Brevo, Constant Contact, Zoho Campaigns, SendPulse, Outlook, Mailgun, Postmark, Sendy, GetResponse, Kit, Moosend, Sender, Mailercloud, or Mailjet. The destination sends the email.
