/ About /

MxToolbox is an online DNS and email diagnostics platform that allows users to look up MX records, check DNS blacklists, verify SPF/DKIM/DMARC, and run network diagnostics. It also offers a RESTful API that lets developers and businesses integrate DNS lookups, reputation checks, and monitor management into their own systems. The platform is widely used by IT administrators, developers, and email managers to troubleshoot and monitor email infrastructure.

/ How it works /

Users enter a domain name to run lookups directly against authoritative name servers, check against 105+ DNS blacklists, and can access all functionality programmatically via a REST API.

/ Who it's for /

IT administrators, developers, and email managers
