Get started

Start with an agent

Build and manage lifecycle email with your agent

Draft the message, connect each workflow step, and keep product, marketing, and transactional email in one place.

Edit emails with your agent

Design every email from one theme

Create a theme, define components or just write in the editor. Do it in the browser or ask your agent. Scale your designs to email in a few clicks.

Introducing themes

Design once, send everywhere

Set your colors, type, and spacing in one place. Every email you send picks them up automatically, so your brand stays consistent without anyone reformatting a template.

Change a token and the whole library follows.
