⚡ Big launch! Meet Flit.

Flit is a lightning-fast drag & drop email builder that outputs clean, client-compatible HTML. Adjust margins and paddings, nest containers, add images, and export in seconds!

Designed to make email creation effortless.

Everything you need to craft high-converting, clean, responsive templates without writing inline table code manually.

Visual Spacing Handles

Resize margin and padding on container edges natively in real-time. Drag handles to perfectly balance negative space on your layout.

Row & Column Layouts

Compose grids instantly. Toggle containers between vertical columns or horizontal rows. Custom gaps manage child elements smoothly.

Bulletproof HTML Output

Flit generates HTML code compatible with Gmail, Outlook, Apple Mail, and Yahoo. Real tables and inline css handle the rendering quirks.

Background Images

Style containers with background images. Set backgrounds to cover or contain, which seamlessly falls back to colors on Outlook.

Flexible Sizing Units

Support both absolute `px` and responsive modern `rem` values for sizing elements, giving full layout controls to designers.

Project Drafts

Save all designs locally on your browser. Easily clone, edit, rename, and load pre-made high-quality email template patterns.
