Email API for developers to send transactional and marketing email

resend.com ↗

Resend goes agent-native with a hosted, OAuth-backed MCP server for email.

◆Current state
Resend is a developer-first email API that has spent the last quarter widening on two fronts. It is building an agent-native surface — an official Claude Code plugin, mentions in AI chats, and now a hosted MCP server — while also creeping past transactional email into audience tooling with CSV contact import, in-email charts, and richer editor previews. The core remains a clean API for sending mail.
◆Where it's heading
The direction is Resend-as-infrastructure that both humans and agents call directly. The MCP thread — a plugin in May, a hosted server in July — turns email into a tool an LLM can invoke over OAuth rather than hand-rolled keys, while the contacts and broadcast work points at competing with marketing-email incumbents, not just transactional senders. Distribution is shifting toward embedding where developers already are, via Vercel's marketplace and Auth0.
◆Prediction
Expect the MCP surface to grow from sending into contact and analytics operations, and the audience and broadcast side to keep maturing toward a full marketing-email offering.

    Remote MCP Server

    ⚡ SPARK

    Extends the agent-native thread from the Claude Code plugin into first-party infrastructure: a hosted MCP server with OAuth means email becomes a tool any agent can call without provisioning keys. It is the clearest sign yet that Resend wants to be the email layer for AI workflows.

    Open Graph Image Previews

    A small composer upgrade that auto-renders link previews, part of the steady polish making Resend's editor feel more like a marketing tool than a raw API. Incremental, but consistent with the move up-market into richer email content.

    Vercel Marketplace Integration

    Distribution rather than product: signing up from inside Vercel or its CLI meets developers where they already deploy. Fits the pattern of embedding Resend into adjacent developer workflows — Auth0, Claude Code — instead of pulling them to a separate signup.

    Import Contacts from CSV

    Bulk contact import with AI column mapping and full SDK coverage pushes Resend further past transactional email into audience management. A prerequisite for competing on broadcasts, and a signal the contacts side is being taken seriously.

    Domain Claim

    An admin-flow addition for a real multi-team pain: reclaiming a domain already verified under another Resend team. Narrow, but the kind of ownership plumbing that matters as larger orgs consolidate onto the platform.

    Official Resend plugin for Claude Code

    The opening move in the agent-native thread the hosted MCP server now completes: packaging the MCP server and skills as an installable Claude Code plugin. Distribution into the agent tooling developers already use.
