Describe it. Postcard designs it.
The email studio where your words become pixel-perfect, client-safe HTML — built by AI, refined by you, sent via API.
Trusted by teams building better email
"Postcard cut our email design time from hours to minutes. The AI understands layout better than most designers."
— Sarah Chen, Head of Marketing at Acme
AI builds what you describe
Describe the email you want in plain language. Postcard AI interprets your intent and assembles a polished, structured email block by block — with real content, real layout, and real style.
- Natural language to email in seconds
- Edits existing emails the same way
One email, every client
Every block renders as table-based, inline-styled HTML that works identically across Gmail, Apple Mail, and Outlook. No more client-specific hacks.
- Gmail, Apple Mail, Outlook — tested
- Table-based layout, inline styles
