MXToolbox: The Established Player
MXToolbox has been a go-to resource for email administrators for years. It offers solid MX record lookups, blacklist checks, and SMTP diagnostics. However, many advanced features require a paid subscription, and even basic tools often require account creation. Their free tier has become increasingly limited over time.
DNSChecker: DNS-Focused Tools
DNSChecker excels at DNS propagation checks and basic DNS lookups. It is useful for verifying DNS changes across global nameservers. However, it has limited email-specific tools, no SSL/TLS analysis, and does not offer comprehensive email authentication checking.
Key Differentiators

- Modern stack: Email Armory is built with current web technologies for fast, responsive results. Some legacy tools feel outdated and slow.
