Resend

ChannelProvider official

Send and receive threaded email through Resend via the Chat SDK.

Install

Install eve, Chat SDK, the Email (Resend) adapter, and a state adapter:

The in-memory state store is for local development. Use Redis or PostgreSQL in production. The adapter is vendor-official.

Quick start

Create agent/channels/resend.ts:

// agent/channels/resend.tsimport { createResendAdapter } from "@resend/chat-sdk-adapter";import { createMemoryState } from "@chat-adapter/state-memory";import { chatSdkChannel } from "eve/channels/chat-sdk";
export const { bot, channel, send } = chatSdkChannel({  userName: "My Agent",  adapters: {    resend: createResendAdapter({      fromAddress: process.env.RESEND_FROM_ADDRESS!,      fromName: "My Agent",    }),  },  state: createMemoryState(),});
bot.onNewMention(async (thread, message) => {  await thread.subscribe();  await send(message.text, { thread });});
bot.onSubscribedMessage(async (thread, message) => {  await send(message.text, { thread });});
export default channel;

// agent/channels/resend.tsimport { createResendAdapter } from "@resend/chat-sdk-adapter";import { createMemoryState } from "@chat-adapter/state-memory";import { chatSdkChannel } from "eve/channels/chat-sdk";
export const { bot, channel, send } = chatSdkChannel({  userName: "My Agent",  adapters: {    resend: createResendAdapter({      fromAddress: process.env.RESEND_FROM_ADDRESS!,      fromName: "My Agent",    }),  },  state: createMemoryState(),});
bot.onNewMention(async (thread, message) => {  await thread.subscribe();  await send(message.text, { thread });});
bot.onSubscribedMessage(async (thread, message) => {  await send(message.text, { thread });});
export default channel;

See the Email (Resend) adapter documentation for all supported events and credentials.

Configure

Verify a sending domain in Resend, set RESEND_API_KEY, RESEND_WEBHOOK_SECRET, and RESEND_FROM_ADDRESS, then point the Resend inbound webhook at /eve/v1/resend. This is a vendor-official Chat SDK adapter. See the Chat SDK channel docs for eve session dispatch, state, streaming, and human-in-the-loop behavior.
