# Chat SDK adds Sendblue support

By Steven Van · 2026-06-22

The vendor-built adapter lets Chat SDK bots send and receive iMessage, SMS, and RCS through Sendblue's hosted gateway.

Chat SDK, the bot framework used with [Vercel](<https://creatorstoolbox.com/tools/vercel>), now has a vendor-official adapter for Sendblue. Bots can send and receive iMessage, SMS, and RCS through Sendblue's hosted gateway, with iMessage-first delivery and automatic fallback to SMS or RCS. The adapter also supports tapbacks, typing indicators, and delivery status callbacks.

Each Sendblue conversation maps to a Chat SDK thread tied to a specific phone line and contact or group, and each inbound iMessage, SMS, or RCS message becomes a Chat SDK message. Read the [Sendblue documentation](<https://docs.sendblue.com/guides/chat-sdk-adapter/>) to get started.
