MCP Resend Email

The MCP Resend Email server bridges the gap between AI assistants and real‑world email delivery by leveraging the Resend API. It enables developers to send a wide variety of emails—plain text, HTML, and attachments—as well as pre‑defined templates for customer service replies, marketing campaigns, and welcome messages. By exposing these capabilities as MCP tools, Claude or any other MCP‑compatible assistant can trigger email workflows directly from natural language prompts, eliminating the need for custom integration code.

For developers building customer support bots or automated marketing pipelines, this server offers a single point of contact for all outbound email logic. Instead of wiring separate SMTP clients or third‑party services, the assistant can invoke , , or any of the other tool names with a simple JSON payload. The server handles authentication, formatting, and attachment encoding internally, allowing the AI to focus on content generation while ensuring reliable delivery through Resend’s infrastructure.

Key features include:

• Versatile email formats: support for plain text, rich HTML, and multi‑part attachments.
• Template‑based workflows: ready‑made customer service, marketing, and welcome templates that automatically populate fields such as recipient name, campaign title, or agent signature.
• Dynamic attachment handling: Base64‑encoded content and MIME type specification enable the AI to send PDFs, images, or any binary data without manual encoding steps.
• SSE and stdio integration: the server can be accessed via standard input/output or Server‑Sent Events, giving teams flexibility to embed it in CLI tools or web services.

Typical use cases include:

• Automated ticket responses: a support bot can generate personalized replies and send them instantly through the tool.
• Campaign management: marketing assistants can draft email copy, insert dynamic CTAs, and dispatch bulk outreach using .
• Onboarding flows: new users receive a welcome email with product details and a call‑to‑action link, all orchestrated by the assistant.

By integrating MCP Resend Email into an AI workflow, developers gain a powerful, reusable email service that scales with their application. The server’s abstraction removes the operational overhead of managing SMTP servers or third‑party APIs, while its template system ensures consistency and compliance across all outbound communications.
