The official MCP server to send emails and interact with Resend
The official MCP server to send emails and interact with Resend. Exposed over MCP by the email sending mcp 💌 mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
Connect your AI agent to the Resend platform. Send and receive emails, manage contacts, broadcasts, domains, and more, directly from any MCP client like Claude, Cursor, or Claude Code.
Everything the assistant can do here goes through one of these:
Emails — Send, list, get, cancel, update, and batch send emails. Supports HTML, plain text, attachments (local file, URL, or base64), CC/BCC, reply-toTemplates — Create, list, get, update, publish, duplicate, and remove email templates. Supports composing template content and {{{VARIABLE}}} placeholdersContacts — Create, list, get, update, and remove contacts. Manage segment memberships, topic subscriptions, and CSV contact imports. Supports custom contactBroadcasts — Create, send, list, get, update, and remove broadcast campaigns. Supports scheduling, personalization placeholders, and preview textAutomations — Create, list, get, update, and remove automations. Review the runs of an automationEvents — Send events to trigger automations for a contact. Create, update, and remove event definitionsDomains — Create, list, get, update, remove, and verify sender domains. Configure tracking, TLS, and sending/receiving capabilities. Create and verify domainSegments — Create, list, get, and remove audience segmentsSuppressions — List, get, add, and remove suppression list entries, individually or in batch. Hard bounces and spam complaints are suppressed automatically; addTopics — Create, list, get, update, and remove subscription topicsWebhooks — Create, list, get, update, and remove webhooks for event notificationsLogs — List and inspect API request logs, including full request and response bodiesBeing a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need 2 environment variables: RESEND_API_KEY, SENDER_EMAIL_ADDRESS. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Email Sending MCP 💌's toolset — Emails, Templates, Contacts and 11 more — is a fair guide to whether it matches your workflow. It is maintained by resend; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
