SEND TIME & FREQUENCY TESTING PLAN:

SEND TIME TESTING:

TIME SLOT VARIATIONS:
Slot A: 8:00 AM (Early morning catch)
Slot B: 10:30 AM (Mid-morning focus)
Slot C: 1:00 PM (Post-lunch check)
Slot D: 4:30 PM (End-of-day review)

DAY-OF-WEEK TESTING:
Week A: Tuesday/Wednesday (Traditional best)
Week B: Monday/Thursday (Catch-up/planning days)
Week C: Wednesday/Friday (Mid-week/week-end)

TIMEZONE CONSIDERATIONS:
• Send in recipient's local timezone
• Test business hours vs. early/late sends
• Account for regional business culture differences

FREQUENCY TESTING:

CADENCE VARIATIONS:
Pattern A: Day 1, 4, 8, 15 (Accelerating intervals)
Pattern B: Day 1, 3, 7, 14 (Consistent spacing)
Pattern C: Day 1, 5, 10, 20 (Increasing intervals)
Pattern D: Day 1, 2, 5, 12 (Front-loaded approach)

VOLUME TESTING:
Low: 3 emails maximum
Medium: 5 emails maximum
High: 7 emails maximum

TESTING METHODOLOGY:

SAMPLE SEGMENTATION:
• Random assignment to time slots
• Minimum 500 recipients per slot
• Control for industry and role differences
• Track cumulative response rates

METRICS TRACKING:
Primary: Response rate by send time
Secondary: Open rate patterns
Tertiary: Unsubscribe rates
Quaternary: Overall campaign ROI

ANALYSIS FRAMEWORK:
• Heatmap of response rates by time/day
• Cumulative response curves by frequency
• Fatigue analysis (diminishing returns)
• Segment-specific optimal timing

IMPLEMENTATION:
• A/B test send times first (2 weeks)
• Apply winning time to frequency test (4 weeks)
• Optimize based on segment-specific results
• Document timezone-specific findings
