SpamJammer — Features & Pricing

Core Engine

Adaptive ML Detection

SpamJammer's core detection engine uses a fine-tuned transformer model (sj-v3-turbo) trained on 2.4B+ labeled messages. The model is retrained hourly on live spam data from the global network. Enterprise customers can fine-tune the model on their own data via the Training API.

Transformer-based architecture (custom 125M parameter model)
Hourly retraining on global spam corpus
Multi-language support: 42 languages
Context-aware: analyzes headers, metadata, and content together
Custom model fine-tuning via POST /v1/models/train
Model versioning with rollback support

Customization

Custom Rules DSL

Define blocking rules using a JSON-based domain-specific language. Rules are evaluated before and after ML scoring, giving you full control over the detection pipeline. Supports regex patterns, keyword blocklists, geographic restrictions, sender reputation checks, and header inspection.

JSON-based rule definitions with AND/OR/NOT operators
Regex pattern matching on content and headers
Keyword blocklist/allowlist management
Geo-fencing: block by country, region, or ASN
Rate limiting per sender, domain, or IP
Rule versioning with A/B testing support
Dry-run mode for testing rules before activation

    "operator": "AND",

    ]
  },

Real-time

Webhooks & Event Streaming

Receive real-time notifications for every spam event. All webhook payloads are HMAC-SHA256 signed for verification. Failed deliveries are retried with exponential backoff (up to 72 hours). Full event replay available via API.

Events: spam.detected, spam.blocked, report.generated
HMAC-SHA256 payload signing
Automatic retry with exponential backoff
Event replay API for disaster recovery
Webhook test endpoint for development

  }
}

Scale

Batch Processing & Async Jobs

Submit up to 1,000 messages in a single API call. Ideal for backfill operations, migration scanning, and periodic audits. Batch jobs run asynchronously with progress tracking and callback support.

Up to 1,000 messages per batch request
Async processing with POST /v1/batch
Progress tracking via GET /v1/batch/:id
Callback URL support for completion notification
Priority queuing for paid tiers
CSV/JSON export of batch results

# Submit a batch of messages
curl -X POST https://api.spamjammer.com/v1/batch \
  -H "Authorization: Bearer sj_live_..." \
  -d '{
    "messages": [
      {"id": "m1", "content": "...", "type": "email"},
      {"id": "m2", "content": "...", "type": "comment"},

Real-time metrics: volume, block rate, latency percentiles
Time-series data with 1-minute granularity
Geographic heatmap of spam origins
Category breakdown and trend analysis
Grafana plugin and Datadog integration
Scheduled PDF reports via email
CSV/JSON export via GET /v1/analytics/export
