Email Deliverability MCP
The goal of the MCPize Email Deliverability & Spam Score project is to help businesses, marketers, and outreach teams improve email deliverability by detecting issues that cause emails to land in spam folders. The platform analyzes email subject lines, body content, formatting patterns, and sender domain authentication records such as SPF, DKIM, and DMARC to identify potential risks before emails are sent.
Overview
Email Deliverability & Spam Score MCP is a tool that analyzes email content and sender configuration to identify issues that may cause emails to land in spam folders instead of the inbox.
The system evaluates:
- email subject lines
- email body content
- sender domain authentication
- spam-trigger patterns
- formatting risks
- deliverability health
It helps businesses improve email performance, increase open rates, and protect sender reputation.
