Introduction
Mailable is vibe email design. Describe an email, sequence, or landing page in plain English and get an on-brand result that renders in every inbox, in the editor or via the API.
What is Mailable?
Mailable is vibe email design. Instead of fighting a drag-and-drop builder or hand-coding HTML, you describe what you want in plain English and Mailable designs it: a polished, on-brand email, automated sequence, or high-converting landing page that renders perfectly in Gmail, Outlook, Apple Mail, and every mobile client, dark mode included.
Use it two ways:
- In the editor as a marketer: chat to generate, nudge blocks to refine, then ship.
- Headless as a developer or LLM agent: call a clean REST API or the MCP server and get back bulletproof, inlined HTML.
Why it exists
Email is the highest-ROI channel, but designing it is slow and fragile. Builders are clunky, hand-coded HTML breaks in Outlook, and generic AI writes copy that doesn't render. Mailable separates intent from markup: you describe the email, and the engine owns layout, responsiveness, brand, and the rendering quirks of every inbox.
What you can build
- Emails for campaigns, newsletters, and transactional messages
- Sequences like onboarding, abandoned cart, and win-back
- Landing pages and funnels that match your campaign
- Decks and other on-brand assets
