Broken email authentication silently sends order confirmations and marketing emails to spam. MailMedic scans your sending domain's SPF, DKIM, DMARC and MX records and grades your email health from 0 to 100. Every failed check includes a plain-language explanation and the exact DNS record to add, ready to copy and paste. Pro monitoring re-checks your domains every 6 hours and emails you when something breaks, before customers stop receiving your emails.
