Hey, it's Zeno.

We've been pushing a ton of agent experience improvements, like adding an official Claude Connector, Codex Plugin, and Remote MCP server. We also started a new partnership with GitHub to keep you safe. Plus, our first-ever conference, Resend Forward, is coming.

Quick question:

What do you wish agents could do with Resend?

Just hit reply. We read every answer.


Claude, Codex, and Remote MCP

A black square with a white "m" logo and the text "New Remote MCP Server" on a dark background.

We launched our remote MCP server that works everywhere. As part of our MCP initiative, we also published an official Claude Connector and a Codex Plugin. Use MCP with all your agents today.

→ Read the changelog


Now supporting OAuth

A screenshot shows a Raycast extension requesting access to a user's Wayback Store account with options for full access or sending access.

We now support OAuth connections to the Resend API. Your app opens an authorization URL, the user approves it on Resend's own consent screen, and you get scoped access tokens back. No API keys change hands, and users can revoke access at any time.

→ Read the changelog


What the new DMARC means for you

A metallic envelope icon next to the text "The New DMARC" and the word "Guide".

After more than a decade of real-world use and several years of drafting, DMARC has a new specification. Here's what changed, and what it means for your domain.

Our new GitHub Partnership

GitHub Secret Scanner logo on a dark background.

Resend is now a GitHub secret scanning partner. When a Resend API key is exposed anywhere GitHub scans (public repositories, gists, issues, and more), GitHub notifies us the instant it appears and we revoke keys automatically. This protects your domain reputation in case there's a leak.

New Vercel Integration

YouTube video

Set up Resend inside Vercel's Marketplace in just a couple of minutes, including provisioning a brand new Resend team, connecting a Vercel domain, and auto-deploying API keys to your project. No DNS wrangling, no copy-pasting env variables.

Message IDs now included in sent emails

JSON code snippet displaying email event data with type, timestamps, sender, recipient, and message identifiers.

We now include message_id in all email webhooks and in the retrieve and list email endpoints. This has been one of our most requested features, and it unlocks new use cases without any new primitives.

→ Read the changelog


Lenny's agentic email workflow

How Agents Power Lenny's Newsletter with Lenny Rachitsky's profile picture and logo.

Resend powers the email behind Lenny's Data, which gives his subscribers all of his posts, podcast transcripts, and more in clean markdown, an MCP server, and a GitHub repo. He set up the entire flow using Claude Code.
