mxio

mxio is a platform focused on email authentication management, specifically SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting, and Conformance) configuration, monitoring, and enforcement. The platform offers two primary service modes: a fully managed option where mxio handles SPF and DMARC records on behalf of the customer, and a self-served option where users retain direct control over their own DNS records. Both modes are supported through a unified dashboard that provides visibility across all domains, protocols, and senders. Core product capabilities include: - Managed SPF: mxio builds and maintains SPF records from a user-defined senders list, automatically resolving IP ranges, deduplicating includes, and republishing changes to stay within the 10 DNS lookup limit. A single DNS delegation to mxio's infrastructure is required. - Managed DMARC: The platform guides domains from a monitoring policy (p=none) through quarantine to full rejection (p=reject) based on actual sender alignment data rather than arbitrary timelines. An "Advisor" feature surfaces unrecognized senders and recommends the next enforcement step. - DMARC Reporting: Parses and classifies aggregate DMARC reports, tracking SPF and DKIM alignment per sender and indicating readiness for policy advancement. - Continuous Monitoring: All plans include always-on monitoring of MX, SPF, DKIM, and DMARC records against authoritative DNS, with AI-generated explanations, incident tracking, and alerting. mxio also provides 23 free, no-signup diagnostic and configuration tools covering SPF, DKIM, DMARC, DNS, SMTP, blacklist checks, email header analysis, and network utilities. Educational guides on email authentication topics are also available. The platform targets organizations managing one or more domains that send email and need to reach or maintain DMARC enforcement without disrupting mail delivery.
