AI agent for frontend developers
Email Rendering Repair Agent
Emails that render correctly in every target layout.
What it does
Approved emails often render badly in some email clients or on some screen sizes. This agent renders the email in every target layout, such as major desktop clients, webmail and phones. It finds the specific defect, like a broken column or a clipped button, and picks a narrow markup repair for it. It then retests all layouts, because a fix for mobile can break desktop. It also checks content and links. If a repair causes a new problem, it narrows the fix. The email lead approves before anything is sent, and the agent never changes the offer. Edge case: a width fix for mobile breaks the desktop columns, so the agent uses a media query.
How it works
Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.
