Cloudflare introduced Email Routing service during 2021's Birthday Week, and later acquired Area 1 Security to enhance email security. The integration processes millions of messages daily and offers insights on email security trends. The new Email Security section on Cloudflare Radar shares metrics on malicious email and threat categorization. It also analyzes dangerous domains, adoption of email authentication methods, and protocol usage like IPv4/v6 distribution and TLS encryption. Cloudflare aims to provide tools for managing and securing emails, offering insights into email threats and technologies to prevent abuse.
