Tracking email performance requires jumping between five different dashboards.

Today, confirming a campaign's health means opening the sender domain dashboard to check verification status. Then you switch over to the message history tab to see if individual emails were sent or bounced. Next, you jump to the activity log just to see opens and clicks. You then have to go back and manually list recipients to ensure they are still active.

With this MCP, your agent pulls all that data into one flow. Instead of clicking through five tabs, you simply ask the agent to 'Show me domain activity for X.' It aggregates the sender details, message metadata, and delivery logs instantly.

MailerSend MCP: Sending Bulk Emails and Managing Domains

The manual steps that disappear are checking DNS records in a separate platform, copying list IDs from one page to another for bulk sends, and cross-referencing bounce lists. You don't have to keep five browser tabs open.

Now you use send_bulk_transactional_emails or the verify_sender_domain tool. Your agent handles the complex API calls in the background; you just get the clear answer.

What MailerSend MCP does for your AI

This MCP connects your agent to the MailerSend API, giving you control over transactional messaging and domain health without touching a dashboard. You can automate everything from sending single emails using templates to running massive batch operations for high-volume campaigns. It gives you visibility into email delivery performance by listing all sender domains and triggering ownership verification checks when needed.

Need to know who opened an email or if it bounced? Your agent pulls real-time logs, letting you access event activity for any domain or retrieve complete metadata on a specific sent message. Plus, you can query your account database using list_email_recipients to ensure your campaign lists are always accurate.

All this goes through your AI client and is available via the Vinkius Catalog.
