You can have the best cold email, written with perfect personalization and value—but if it lands in your prospect’s inbox at the wrong time, it might never be read.
Timing is one of the most underrated success factors in cold email outreach. Let's break down the best days and times to send cold emails in 2025, based on current data and expert insight.
🔹 1. Why Timing Matters in Cold Outreach
Sending your emails when people are most likely to open and read them increases:
Open rates
Reply rates
Click-through rates
Meeting conversions
People are busy. You need to reach them when they’re most receptive, not just available.
🔹 2. Best Days to Send Cold Emails
According to studies and outreach tools like Lemlist, Mailshake, and HubSpot, the top-performing days are:
Tuesday
Wednesday
Thursday
These are mid-week days when people are not overwhelmed like Monday or checked out like Friday.
Avoid:
Mondays – inboxes are crowded with weekend emails.
Fridays – people are winding down for the weekend.
🔹 3. Best Time of Day to Send Cold Emails
Morning hours work best, especially:
8:00 AM to 11:00 AM – people check emails first thing in the morning.
Other effective time windows:
1:00 PM to 3:00 PM – post-lunch productivity window.
Evening (5:00 PM – 6:30 PM) – for busy professionals who check after hours.
Avoid:
Lunch hours (12–1 PM)
Late evenings or weekends
🔹 4. Consider Time Zones
Always schedule emails based on the recipient’s time zone, not yours.
Use tools that auto-adjust or segment your email lists by region. If you're reaching global prospects, batch emails by time zone blocks.
🔹 5. A/B Test Your Send Times
Don’t rely only on general data. Test your audience. Try different times and track:
Open rates
Click rates
Reply rates
Use platforms like Mailtrack, GMass, or Yesware to monitor results.
🔹 6. Use Send Scheduling Tools
Instead of sending manually, use smart tools to queue and schedule:
Lemlist
Mailshake
Snov.io
GMass
These tools help you hit inboxes at the exact right time—even when you’re asleep.
