Chat SDK now supports Sendblue with the new [vendor-official adapter](https://chat-sdk.dev/adapters/vendor-official/sendblue).

Build bots that send and receive iMessage, SMS, and RCS through Sendblue's hosted gateway, reaching people on the messaging apps they already use. Messages use iMessage-first delivery with support for automatic SMS and RCS fallback, tapbacks, typing indicators, and delivery status callbacks.

**lib/bot.ts**
```typescript
import { Chat } from "chat";
import { createSendblueAdapter } from "chat-adapter-sendblue";
import { createMemoryState } from "@chat-adapter/state-memory";
const chat = new Chat({
  userName: "imessage-bot",
  adapters: {
    sendblue: createSendblueAdapter(),
  },
  state: createMemoryState(),
});
chat.onDirectMessage(async (thread, message) => {
  await thread.post(`Got it: ${message.text}`);
});
```

The adapter maps each Sendblue conversation to a Chat SDK thread, tied to a specific phone line and contact (or group), and each inbound iMessage, SMS, or RCS message to a Chat SDK message.
