// What’s different
Three ideas, taken seriously.
Most email builders bolt AI onto a 2008 interface. Postern starts from a different question: what if AI was the primary way to compose?
One template. Multiple audiences.
Show different content to different subscribers without writing code. The visual conditional builder handles drag-and-drop logic. Easier than conditional syntax.
Edit emails on your iPad. Actually works.
A 12-minute design on your couch beats a 2-hour desktop grind. Postern is touch-native. No pinch-zoom hacks.
// Try it
Edit a real email right here .
Drag a block from the sidebar. Ask the AI to rewrite the headline. Apply the diff. No signup, nothing saved beyond this tab.

Demo runs entirely in your browser. The AI uses canned responses for common prompts; novel prompts hit a real model only when we’re certain it stays under our cost ceiling.
