AI-Optimized Email Send Times
Boost open rates and engagement by delivering every email at each recipient’s ideal moment. Automate analysis that used to take 6–12 hours and implement optimized send times in minutes.
Executive Summary
AI analyzes behavioral history, engagement patterns, and delivery effectiveness to determine the best send time for each contact. Teams typically achieve a 23% lift in open rates while cutting manual effort by 92%, moving from multi-hour analyses to automated, per-recipient optimization in under 30 minutes.
How Does AI Improve Send-Time Performance?
Instead of batching by a single global “best time,” AI personalizes send windows at the recipient level. This improves inbox placement and real-world visibility, driving sustained gains in open and click-through rates without increasing email volume.
What Changes with AI Send-Time Optimization?
🔴 Manual Process (6–12 Hours, 8 Steps)
- Historical engagement data export and prep (1–2h)
- Time zone research and normalization (1h)
- Audience behavior analysis and segmentation (1–2h)
- Design and configure A/B timing tests (1h)
- Run campaign and collect results (—)
- Performance tracking and statistical checks (1–2h)
- Create recommendations and send windows (1h)
- Manual scheduling updates and monitoring (30m–1h)
🟢 AI-Enhanced Process (≈30 Minutes, 2 Steps)
- AI behavioral analysis to determine optimal per-recipient send time (20–25m)
- Automated scheduling and real-time adjustments (5–10m)
TPG standard practice: Start with a 2–4 week learning window, set confidence thresholds for automatic overrides, and maintain a fallback window per segment for low-data contacts.
Key Metrics to Track
Target Outcomes
- Engagement Timing Fit: Higher share of opens within 60 minutes of delivery
- Deliverability Health: Lower spam complaints and higher inbox placement
