Frequently asked
The score out of 100 reflects how well your domain is configured for reliable email delivery. It combines MX records (30 points), SPF (25 points), DMARC (30 points), and blacklist status (15 points). A score above 80 means your domain is well configured. Below 50 means you likely have deliverability problems already.
