What's the best time to send Cyber Monday emails?

Question

As an e-commerce marketer, I'm struggling to determine the optimal timing for my Cyber Monday email campaign. With so many businesses competing for customer attention, I need to find the precise moments when my emails are most likely to be opened, read, and drive conversions. I want to understand the psychology behind email timing, consider different time zones, and maximize my campaign's potential without overwhelming my subscribers or getting lost in crowded inboxes.

Best Time to Send Cyber Monday Emails
Timing Cyber Monday emails correctly can improve open rates by 15-25% versus sending at suboptimal windows. The goal is to reach subscribers when they are actively checking email with purchase intent, not when they are in meetings or asleep.

Timezone Considerations

US-based audiences: Send in EST - covers the largest population; PT audience gets it slightly earlier (5-6 AM) but CM shopping still peaks later
Global audiences: Use timezone-based send if your ESP supports it, or schedule around your largest geographic cluster
Mixed audiences: Default to EST with a clear timezone note in your deadline ("11:59 PM EST") so all subscribers can calculate their local cutoff

What Data to Use for Timing

- Check your ESP analytics for your audience's peak open time from previous campaigns
- Look at your Black Friday email open patterns - CM audience behavior is similar
- Use your A/B test winner's send time as the model for subsequent emails
