About this tool
mailcheck is a free tool that verifies whether a domain's email can be trusted by checking MX records, SPF, and DMARC configurations. It surfaces silent misconfigurations that cause mail to land in spam or get spoofed, with a paid option that adds DKIM selector probing and ready-to-paste fix snippets. No signup is required to run a basic check.
