Real-Time FCrDNS Validation & Holistic Infrastructure Auditing
Definitively calculate your comprehensive Sender Trust Score and fundamentally secure your global inbox placement by executing a rigorous, real-time audit of your holistic trust profile. Completely bypassing flawed estimations, our high-performance C# backend executes live, direct DNS queries to strictly evaluate your exact Authentication Weight (actively identifying enforced DMARC p=reject policies), definitively validate Forward-Confirmed reverse DNS (FCrDNS) infrastructure, and rigorously audit advanced BIMI Brand Indicators. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, we instantly deploy dynamic MX auto-discovery to aggressively cross-reference your active sending IP against authoritative global RBLs (such as Spamhaus), programmatically aggregating these critical layers into a precise 0-100 Trust Score that accurately categorizes your domain as High Risk, Warming Up, or securely Established.
Spam filters evaluate more than just blacklists. They look at your holistic Trust Profile: DMARC strictness, FCrDNS alignment, Brand Indicators (BIMI), and infrastructure health. Enter your domain to calculate your comprehensive Sender Trust Score.
Modern Inbox Providers (Gmail, Outlook) use complex machine learning algorithms to evaluate senders. They look beyond simple pass/fail checks to establish a "Trust Score" for your brand.
p=reject is trusted significantly more than a domain with p=none. We analyze the strictness of your DMARC and SPF policies to gauge your identity strength.Your feedback has been submitted successfully. We appreciate your help in improving our tools.
