Beautiful email, without the busywork
Drag-and-drop builders fight you on design. MJML and hand-coded HTML solve rendering but not speed. Generic AI writes copy but breaks the markup. Mailable is the missing middle: describe what you want, get on-brand email that renders everywhere - in the editor or via the API.
Describe it, don’t drag it
You write a sentence and get a finished, on-brand email. Refine by chatting or nudging blocks - never by wrestling layout.
Where others fall short
Drag-and-drop builders
You hand-place every block, and the last 30% is a fight.
Beefree / Stripo
Faster than HTML, but still manual design work.
Generic AI writers
Great copy, but no real design or layout.
It renders in every inbox
Output is table-based, inlined, and tested against Gmail, Outlook, Apple Mail, and mobile - dark mode included. It just renders.
Where others fall short
Hand-coded HTML
Bulletproof only if you test the whole client matrix yourself.
AI-generated HTML
Looks fine in a browser, breaks in Outlook.
MJML
Solves rendering, but you still write the markup.
Marketers and machines
The same engine runs in a calm editor for marketers and a headless API + MCP server for developers and LLM agents.
Where others fall short
Email builders
A UI with no real API for your code or agents.
Email frameworks
Developer-only - non-technical teammates can’t touch it.
ESP editors
Built for sending, not for designing from intent.
On-brand by default
Your colors, fonts, logo, and voice are baked into every generation, with lockable rules so nothing off-brand ships.
Where others fall short
Generic AI
Output drifts off-brand with every prompt.
Template galleries
One-size templates you bend toward your brand by hand.
Drag-and-drop builders
Brand consistency is manual and easy to break.
The whole funnel, one brief
Emails, automated sequences, and the landing pages they link to - all designed from the same brand and the same prompt.
Where others fall short
ESPs
Email and flows, but not the landing page behind them.
Page builders
Great pages, but a separate tool from your email.
Point tools
One artifact at a time, stitched together by hand.
No lock-in on sending
Send from Mailable, or push designs to Mailchimp, Klaviyo, Salesforce, your ESP - or export clean HTML. Your work is portable.
Where others fall short
All-in-one suites
Design is trapped inside the suite you send from.
Proprietary builders
Exports are messy and tied to the platform.
Closed editors
Designs don’t travel cleanly to other tools.
