Key technical decisions
- High-volume sending infrastructure with domain and reputation management
- Email validation pipeline to reduce bounces before campaigns go out
- AI spam-score analyzer for trigger words, broken links, and blacklist risks
- Warmup automation that builds sender reputation with gradual engagement patterns
- Real-time analytics for opens, clicks, conversions, and revenue impact
