Mailgenius checks whether your emails will reach the inbox or get flagged as spam.
Updated April 2026
Overview: What is Mailgenius?
It scans authentication records, blacklists, and content to surface deliverability problems. Teams use it to protect sender reputation and improve open rates.
Mailgenius is an email deliverability platform that audits outgoing messages before they reach prospects. Users send a test email to a dedicated address and receive a detailed report covering SPF, DKIM, and DMARC alignment. The tool checks domain and IP blacklists, previews inbox placement across major providers, and flags spam triggers in subject lines and body copy. It also verifies unsubscribe headers and detects broken links that could hurt sender reputation. An AI consultant feature provides actionable recommendations based on each scan. Higher tiers add domain monitoring, blacklist alerts, and competitor email testing for ongoing protection.
Fit: Ideal customer profile.
