Email HTML editor
Paste a full email HTML document. The canvas reconstructs it so you can inspect spacing and type, then open source and see the same markup.
Paste React Email or HTML
Opens on a visual canvas. Inspect styles, then flip to source. Nothing is saved or sent.
Paste once. Edit visually. Keep the source.
A browser-only loop for React Email and table HTML — no login and no send.
Paste, don’t rebuild
Drop in React Email or table-based HTML. The canvas keeps the column, images, and buttons instead of flattening the layout.
Inspect the same tree
Select a heading, cell, or button. Padding, color, and type edit the live document — then source updates to match.
Source stays in sync
Flip to <>. Canvas typing and inspect writes compose back into the HTML. Edit source and the canvas updates.
Nothing leaves the browser
No account, save, send, or test. The document lives in this tab until you copy it out.
