Time Zone Considerations

Always use recipient's local time zone:

• Don't send at 10 AM EST to someone in PST (that's 7 AM their time)
• Use customer data to determine time zone
• Adjust for daylight saving time

Multi-region campaigns:

• Segment by time zone
• Stagger sends appropriately
• Consider regional preferences (lunch times vary by culture)

Special Timing Scenarios

Cart abandonment:

• Send immediately (1-3 hour window is critical)
• Follow up at 24 hours if no conversion
• Final reminder at 72 hours
• Don't worry about "optimal time" — speed matters more

Appointment reminders:

• 24-48 hours before appointment
• 1-2 hours before appointment (confirmation)
• Send during business hours

Shipping updates:

• Send when status changes (immediate)
• Delivery day: morning for "out for delivery"
• Delivery confirmation: immediate

Event-based:

• Event reminders: 1 week, 1 day, 1 hour before
• Ticket sales: When they go on sale
• Limited offers: Immediately when launched

A/B Testing Send Times

Test different times with small segments:

Test setup:

• Segment A: 10 AM send
• Segment B: 6 PM send
• Measure: open rate, click rate, conversion, opt-out

What to measure:

• Open rate by send time
• Click-through rate by send time
• Conversion rate by send time
• Opt-out rate by send time
• Revenue per message by send time

Duration:

• Run test for 2-4 weeks
• Account for day-of-week variations

The Bottom Line

For most campaigns: Tuesday-Thursday, 10 AM-12 PM or 6 PM-8 PM in recipient's time zone. For time-sensitive messages: send immediately, don't wait for "optimal" time. And always test and optimize based on your specific audience engagement patterns.

The best send time is when your specific customer is most likely to engage. Use data to find that window, then respect it.
