AI Email Automation: Smart Campaigns with Agent Skills

Workflow Walkthrough

AI email automation follows five stages. Each maps naturally to one or more of the skills above.

Stage 1: Trigger

Triggers can be event-based or time-based. Gmail MCP enables event-based triggers: the agent watches your inbox for specific patterns — a new email from a target domain, a subject line containing a keyword — and fires downstream automation when matched. The Calendar skill enables time-based triggers: send a reminder email 48 hours before each meeting on your calendar where the event has more than two attendees.

Stage 2: Draft

The Draft stage is where AI agents provide unique value over traditional automation. Instead of populating a fixed template with merge tags, the agent reads context about the recipient from the Notion template library, the CRM, or the calendar event, and composes a message that reflects that context. The result is an email that feels written by a person who knows the recipient, rather than generated from a template.

Stage 3: Personalize

Personalization goes beyond first name and company name. The agent can reference: the product the recipient is using, a blog post they published recently, the meeting agenda from Notion, or the support ticket they filed three days ago. The more context you give the agent access to, the more specific and relevant the personalization becomes.

Stage 4: Send

Sending routes through the appropriate skill based on message type. Transactional and bulk messages go through Resend for guaranteed deliverability. Campaign messages go through Mailchimp to leverage audience segmentation and engagement analytics. Personal and relationship emails go through Gmail MCP so they appear to come from your actual email address.

Stage 5: Track

After sending, the agent pulls engagement metrics. For Resend, this means querying the event log for opens, clicks, and bounces per message. For Mailchimp, it means retrieving campaign reports. The agent compiles these into a structured summary and can flag underperforming messages for review: any email with an open rate below 20% gets flagged with its subject line and send time for analysis.

Step-by-Step Setup

The following configuration sets up Gmail MCP, Resend skill, and Notion MCP as a minimal email automation stack. Add Mailchimp and Calendar skills as your use case expands.

Step 1: Add Skills to Your MCP Config

{
  "mcpServers": {
    "gmail": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-gmail"],
      "env": {
        "GMAIL_CLIENT_ID": "your_oauth_client_id",
        "GMAIL_CLIENT_SECRET": "your_oauth_client_secret",
        "GMAIL_REFRESH_TOKEN": "your_refresh_token"
      }
    },
    "resend": {
      "command": "npx",
      "args": ["-y", "mcp-server-resend"],
      "env": {
        "RESEND_API_KEY": "re_your_api_key"
      }
    },
    "notion": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-notion"],
      "env": {
        "NOTION_API_KEY": "secret_your_notion_key"
      }
    }
  }
}

Step 2: Verify Each Connection

• "Show me the last 5 emails in my inbox" — verifies Gmail MCP
• "Send a test email to [email protected] with subject MCP test" — verifies Resend skill
• "List all pages in my Email Templates Notion database" — verifies Notion MCP

Step 3: Run Your First Automated Sequence

"Read the Welcome Email template from my Notion
Email Templates database. Personalize it for
[name] at [company] who signed up for the Basic plan.
Send the result via Resend to [email] from [email protected].
Log the send in the Notion Sent Log database with timestamp."

Step 4: Add Calendar and Mailchimp Skills

Add the Calendar skill for time-based triggers and the Mailchimp skill for bulk campaign management following the same pattern as the configuration above, providing each skill\u0027s required API credentials.
