Sendable

One line, and your app knows how to talk to its users.

You describe what happened; Sendable writes the message and sends it. No templates to maintain, no dashboard step — your data is never rewritten, only the words around it.

npm i sendableme
import { send } from 'sendableme';

await send('sam@example.com', 'order_shipped', { orderId: 'A-1042', eta: 'Friday' });

That's a complete integration. Adding a new message type is a new string.

What's in this repo

Your data is never rewritten

The model that writes the copy never sees your values — only your field names. It writes copy containing {{placeholders}}, and your values are substituted afterwards, so a price, a date, or a reset link cannot be altered. A second model checks every draft for claims your data doesn't support and refuses rather than guess.

await send(user.id, 'payment_failed', { amount: '$99.00' });
// "$99.00" appears exactly as written, always

MCP
