Supermail uses a two-tier security system that combines instant local scanning with advanced AI analysis. Every email is checked before you even see it.
Our security system runs two independent checks on every email, catching threats that single-layer systems miss.
Lightning-fast analysis that runs entirely in your browser. Catches known threats in milliseconds without sending data anywhere.
Advanced language models analyze email content for sophisticated attacks that evade traditional filters.
Every email passes through our comprehensive validation pipeline before reaching your inbox.
Domain authentication, sender reputation, SPF/DKIM/DMARC validation, and first-time sender detection.
Content scanning for urgency tactics, pressure language, manipulation patterns, and social engineering attempts.
Weighted contextual analysis using AI to detect sophisticated attacks, impersonation, and business email compromise.
Block scripts, disable tracking pixels, neutralize dangerous links, and prevent any interaction that could expose you.
From obvious spam to sophisticated attacks, Supermail identifies threats before they reach you.
Fake login pages, credential harvesting, and deceptive links designed to steal your information.
Emails pretending to be from your boss, bank, or trusted contacts to trick you into action.
Malicious attachments and links that can encrypt your files and demand payment.
Fake invoices and payment requests that redirect money to criminal accounts.
Pressure tactics claiming your account will be closed or you'll miss an opportunity.
Hidden downloads and drive-by attacks disguised as legitimate websites or documents.
We built Supermail with privacy as a core principle. Protection shouldn't require giving up your data.
Tier 1 scanning runs entirely in your browser. Your emails never leave your device for basic threat detection.
We don't store your emails. Period. AI analysis processes content in memory and immediately discards it.
Choose which emails get AI analysis. Disable it entirely if you prefer local-only scanning.
