How to Use the MailerSend MCP in Claude Code

Q: How do I use Claude Code to check MailerSend email logs?

Run a command with the listsentmessages tool to get a list of recent sends. You can then pipe a specific message ID to getsentmessagedetails for a full status report, all within your terminal.

Q: Can I add a new sending domain to MailerSend using Claude Code?

Yes. Use the verifysenderdomain tool. You can then write a simple shell script to poll getsenderdomaindetails until the domain is confirmed by MailerSend.

Q: What's the process to connect Claude Code to the MailerSend server?

Run claude mcp add --transport http mailersend -- in your terminal. This adds the MailerSend MCP Server to your /.claude.json config file so you can start using the tools.

Q: How do I list all recipients in my account?

Use the listemailrecipients tool. You can pipe the JSON output directly to tools like jq for filtering or wc -l to get a quick count.

Q: How is data handled when I use the MailerSend MCP Server with Claude Code?

The server processes recipient email addresses and the text or html body you pass to sendtransactionalemail. Your connection is authenticated by your unique MCP token, and operations run in a zero-trust, ephemeral container on Vinkius.

Run MailerSend API calls from your terminal. Connect Claude Code to script domain management, send emails, and check delivery status in any shell.

Script Your Transactional Emails

The `send_transactional_email` tool lets you fire off emails directly from a script. Just construct the JSON body with sender, recipient, and content, then pipe it to your Claude Code agent. It's built for CI/CD pipelines and cron jobs. For bigger jobs, use `send_bulk_transactional_emails`. You can generate a list of recipients from a database, format it as a single JSON payload, and send it all in one command. No SDKs or complex authentication required.

Automate Domain Management with this MCP Server

Manage your sending domains from the command line. Use `list_sender_domains` to see what's configured, and pipe the output to `grep` or `jq` to find what you need. It's faster than any web UI. When you add a new domain, run the `verify_sender_domain` tool. You can create a simple bash script that calls `get_sender_domain_details` in a loop until the 'is_verified' field returns true, then sends a notification. This is headless automation.

Monitor Email Delivery in Terminal

Check on your email delivery without leaving the terminal. The `list_sent_messages` tool gives you a raw log of recent sends. For more detail, grab a message ID and pass it to `get_sent_message_details`. This is powerful for debugging. Pipe the output of `list_domain_activity` to a log file or another monitoring tool. You can build simple, effective alerting on email bounces or spam complaints right from your shell with this MCP Server.
