Cold Email Timing & Frequency: The Science of Perfect Outreach
Timing is everything in cold email outreach. Send your emails at the wrong time, and they'll get buried in inboxes. Use the right timing and frequency, and you'll see your response rates skyrocket.
Why Cold Email Timing Matters
Cold email timing affects every aspect of your campaign success:
- Open Rates: Emails sent at optimal times get opened more
- Response Rates: Better timing leads to more replies
- Engagement: Recipients are more likely to engage when they're active
- Deliverability: Proper timing improves inbox placement
