Score: 5.0/10 (Innovation: 4, Technical: 5, Documentation: 3, Utility: 6)

MXValidation is a hosted service that analyzes an email's authentication (SPF, DKIM, DMARC), DNS configuration, SpamAssassin signals, and sending-IP reputation by having users send a test message to a unique address. It fills a practical gap for developers and email senders who need a quick deliverability diagnostic without manually checking each technical component.

Target audience: backend devs, devops, email marketers
