## Scoring System
The deliverability score is calculated from 0 to 10 based on:
The deliverability score is calculated from A to F based on:
- **Authentication (3 pts)**: SPF, DKIM, DMARC validation
- **Spam (2 pts)**: SpamAssassin score
- **Blacklist (2 pts)**: RBL/DNSBL checks
- **Content (2 pts)**: HTML quality, links, images, unsubscribe
- **Headers (1 pt)**: Required headers, MIME structure

- 9-10: Excellent
- 7-8.9: Good
- 5-6.9: Fair
- 3-4.9: Poor
- 0-2.9: Critical
- **DNS**: Step-by-step analysis of PTR, Forward-Confirmed Reverse DNS, MX, SPF, DKIM, DMARC and BIMI records
- **Authentication**: IPRev, SPF, DKIM, DMARC, BIMI and ARC validation

- **Spam**: SpamAssassin score
- **Content**: HTML quality, links, images, unsubscribe
