Perplexity

Send Emails on the Fly

The `send_transactional_email` and `send_templated_email` tools let you fire off emails right from the chat prompt. Tell Claude to send a password reset to a user or push a receipt for a new order. Just describe what you need, and your agent handles the API call. There's no need to open your codebase or a separate email client. You can stay focused in Claude and handle routine email tasks conversationally. It's faster than writing a script and simpler than navigating a dashboard.

Check Delivery Status and Analytics

Use the `get_message_info` and `list_email_activities` tools to see if your emails are actually landing. Ask Claude, "Did that welcome email to user@example.com get delivered?" and get a straight answer, not a vague guess. It's direct access to your MailerSend logs. You can also pull performance metrics right into your chat. Ask for a summary of yesterday's stats, and the `get_date_analytics` tool fetches your open, click, and bounce rates. This gives you a quick pulse on deliverability without opening another browser tab.

Manage Templates and Domains in Claude Desktop

Before sending a campaign, you can ask Claude to list all your available MailerSend templates. The agent uses `list_email_templates` to pull the current list with their exact IDs, so you don't send the wrong one by mistake. It's a simple check that prevents common errors. This MCP Server integration lets you manage your email infrastructure from your chat window. Check on your verified domains with `list_sending_domains` or inspect webhook configurations with `list_domain_webhooks`. It turns operational chores into simple questions.

Common questions about MailerSend MCP in Claude Desktop

Just ask Claude, "Using MailerSend, send an email to..." and provide the recipient, subject, and body content. Your agent will use the `send_transactional_email` tool to send it immediately.

Yes. Ask, "What are my current MailerSend account limits?" Claude uses the `get_account_limits` tool to pull your plan's quotas for sends, domains, and API usage.

The MailerSend tools communicate with a cloud API, so you'll need an internet connection for them to function. Even in local mode, the MCP server simply acts as a bridge from Claude on your machine to the MailerSend service online.

Ask Claude to show you recent email activity. It uses `list_email_activities` to pull a log of events like deliveries, opens, and clicks, giving you a quick summary right in the chat.

The server only handles the data required to send an email, like recipient addresses and message content passed to the `send_transactional_email` tool. Your Vinkius endpoint authenticates the connection, and the server doesn't access any other local files or data on your machine.
