About SMTPCart
Engineered for seamless email infrastructure optimization, the Email Deliverability Tool by SMTPCart delivers instant, enterprise-grade visibility into your domain health and inbox placement potential. By sending a single test message to a custom-generated diagnostic address, users receive a real-time deliverability score out of 100% and a downloadable, audit-ready PDF report detailing full system compliance. The tool conducts an exhaustive, real-time security assessment—verifying SPF, DKIM, and DMARC alignment while testing reverse DNS, TLS encryption, and RFC-compliant one-click unsubscribe headers. To protect your domain against delivery failures, it simultaneously audits content against SpamAssassin rules and screens sending assets across 20 global IP blocklists alongside the Spamhaus domain registry—all accessible immediately without any account registration or sign-up.
