Real-Time Apache SpamAssassin Scoring & Content Diagnostics
Definitively guarantee your campaigns pass aggressive enterprise firewalls by executing a rigorous, real-time heuristic audit of your raw email source code. Completely eradicating flawed simulators and mocked tests, our high-performance C# backend directly executes exact open-source anti-spam algorithms (including authentic Apache SpamAssassin rules), precisely parsing your EML payload into tokens to run dozens of live, regex-based heuristic checks. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, we actively calculate a precise cumulative penalty score by enforcing strict Header Authentication checks, executing genuine Bayesian content scanning for promotional keywords, and performing deep URI/URL analysis to definitively ensure your transactional and marketing emails consistently bypass aggressive filters and achieve perfect inbox placement.
Simulate how enterprise email filters (like Apache SpamAssassin) score your messages. Paste your raw email source code to execute a suite of heuristic tests covering headers, authentication, HTML structure, and spammy phrasing.
Our engine mimics the behavior of popular open-source anti-spam systems. It parses your email into tokens and runs dozens of regex-based heuristic checks.
