How these reports are built
Each report scores a domain against DNS hygiene, email authentication (SPF, DKIM, DMARC), DNSSEC, IPv6 readiness, and transport security, then rolls those checks up into an overall grade. For the aggregate findings across this corpus, read our State of Email Security study. You can also explore the scoring methodology or browse the free DNS & email tools.
