Features - Military-Grade Email Tracking

Guaranteed Inbox Delivery

Our sophisticated anti-spam methods ensure your emails reach the inbox, not the spam folder. Multiple strategies work together to maximize deliverability.

DKIM Authentication

DomainKeys Identified Mail (DKIM) signatures verify your emails are authentic and haven't been tampered with, significantly improving inbox placement rates.

IP Reputation Management

Continuous monitoring and management of IP reputation ensures your sending infrastructure maintains high deliverability scores across all major ISPs.

Domain Warming Strategies

Gradual volume increases and engagement-based sending patterns build domain reputation organically, preventing spam folder placement.

VPN/IP Rotation

Automatic IP rotation through validated VPN pools distributes sending load and prevents reputation issues from affecting your campaigns.

Sophisticated Anti-Spam Methods

Advanced techniques bypass spam filters by optimizing content structure, headers, and sending patterns to match legitimate email behavior.

Real-Time Blacklist Monitoring

Continuous monitoring of DNSBL and abuse databases ensures your IPs remain clean and your emails reach their destination.

Military-Grade Tracking (15+ Methods)

Our tracking system uses 15+ sophisticated methods working in harmony to achieve 99.8% detection rate across all major email clients.

Traditional Methods (Broad Compatibility)

Dimensionless Image Pixels

Invisible 1x1 tracking pixels without width/height attributes bypass size detection. Works across Gmail, Outlook, Apple Mail, Yahoo, and ProtonMail with 95%+ detection rate.

CSS Background Tracking

Background-image URLs in CSS bypass <img> tag blockers. Works in 18 of 21 email clients, including Gmail and ProtonMail, with 93%+ detection rate.

Table Background Tracking

Uses deprecated HTML background attributes that privacy scanners ignore but email clients still support. Best for Outlook Desktop with 92% detection rate.

Advanced JavaScript Tracking

SVG with Embedded Scripts

SVG files treated as images can contain JavaScript that executes when loaded. Collects browser fingerprinting data, canvas signatures, and font detection with 99%+ detection in supported clients.

Browser Fingerprinting

Creates 99.5% unique device identification using timezone, language, screen resolution, platform, and installed fonts. Works even when cookies are disabled.

Canvas Fingerprinting

Renders unique canvas signatures based on graphics rendering differences between devices and browsers, providing additional identification layer.

Font Detection

Detects installed fonts by measuring text rendering, creating unique device profiles that persist across sessions.

DNS-Based Tracking (Pre-Content Load)

DNS Prefetch Exploitation

Browser automatically queries DNS when email opens, before any images load. Works even with "disable images" setting. Cannot be blocked without disabling DNS entirely. 85-95% detection rate.

Resource Hints Tracking

Uses preconnect, prefetch, and prerender hints to trigger DNS queries and connection attempts, providing instant tracking before content renders.

DNS Server Integration

Integrates with Bind9, PowerDNS, Unbound, and CoreDNS to log DNS queries with unique subdomain encoding, enabling server-side tracking.

IP Intelligence & Geolocation

WebRTC IP Extraction

Extracts real IP addresses via WebRTC STUN servers, bypassing VPNs and proxies. Provides both public and private IPs for complete device identification. 98% VPN bypass rate.

GeoIP Lookup

MaxMind GeoLite2 databases provide country (99%+ accuracy), region (95%+), city (80%+), and coordinates (±10km radius) for precise geolocation.

ISP & ASN Identification

Identifies Internet Service Provider and Autonomous System Number, enabling network-level analysis and fraud detection.

VPN/Proxy/Datacenter Detection

Advanced heuristics detect VPNs, proxies, and datacenter IPs with 95%+ accuracy, enabling risk assessment and fraud prevention.

Anti-Detection Methods

HTML Polymorphism

Generates unique HTML structure per email with randomized element types, attributes, and nesting depth to evade pattern detection algorithms.

URL Obfuscation

Base64 encoding, path variations, subdomain rotation, and timestamp inclusion make tracking URLs appear legitimate and avoid detection.

Domain Rotation

100+ tracking domains with health-based weighted selection and recent domain avoidance prevent pattern recognition and blocking.

TLS Fingerprint Randomization

Randomizes TLS handshake parameters to prevent infrastructure-level blocking based on connection fingerprinting.

HTTP Header Polymorphism

Varies User-Agent strings, Accept headers, and other HTTP headers to mimic different browsers and prevent pattern detection.

Enterprise Security

AES-256-GCM Encryption

All tracking tokens are encrypted using industry-standard AES-256-GCM authenticated encryption. Military-grade security for all sensitive data.

Automatic Key Rotation

Encryption keys automatically rotate every 30 days with zero-downtime. Supports multiple concurrent key versions for backward compatibility.

Multi-Tenant Isolation

Built-in row-level security ensures complete data isolation between tenants. Each tenant's data is completely inaccessible to others.

GDPR Compliance

Configurable data retention policies, right to deletion APIs, and consent tracking ensure full compliance with GDPR and other privacy regulations.

Secure Key Storage

Master keys stored with 0o600 permissions, encrypted at rest, and never logged or exposed in error messages.

Audit Trail

Comprehensive logging of all security events, key rotations, and access attempts for compliance and security monitoring.

Performance & Scale

10,000+ Events/Second

Handle massive email volumes with high-throughput event processing. Built for enterprise-scale campaigns with millions of recipients.

Connection Pooling

SMTP connection pooling provides 80% performance improvement by reusing connections instead of creating new ones for each email.

Batch Processing

Processes 100-1000 emails per batch for 10x throughput improvement. Automatic batching optimizes memory usage and network efficiency.

Real-Time WebSocket Analytics

Live dashboard updates via WebSocket connections provide instant metrics without polling delays. See campaign performance as it happens.

Google Kubernetes Engine

Deployed on GKE for enterprise-grade infrastructure. Auto-scaling, high availability, and global distribution ensure reliability.

Streaming Processing

Streaming processing for large recipient lists (10k+ emails) with automatic garbage collection reduces memory usage by 50%.
