Why choose Reloop's
email HTML editor
A visual canvas and the HTML source, kept in sync as you edit. Free to use in your browser, with nothing to install.
Start from a template
Open a ready-made email on the canvas. Columns, images, and buttons stay editable blocks, and you can paste your own HTML over it.
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 code. Canvas typing and inspect writes compose back into the HTML. Edit source and the canvas updates.
No account to start
Edit freely in this tab. When you're happy, save it to Reloop Templates with a free account.
