Why Check Your Email Infrastructure Health?
A misconfigured SPF record, a missing DKIM signature, or a DMARC policy stuck at p=none are the top reasons legitimate emails land in spam, sales pitches die in quarantine, and your domain becomes a free playground for impersonators. Every external receiver, Gmail, Outlook, Apple Mail, corporate gateways, scores your domain across these signals before deciding to deliver, junk, or reject.
This tool runs a live audit of every email signal that matters: SPF, DKIM (across 105 selectors auto-detected from major ESPs), DMARC, MX, SMTP banner, TLS, MTA-STS, BIMI, DNSSEC, CAA, and reputation across 12 public RBL blacklists. Fix what we flag and your deliverability, brand protection, and compliance posture all improve in one shot. Want the exact DNS records to publish?
