The Best Time to Send Emails in 2025: A Data-Driven Guide

You can have the perfect subject line and an engaging message, but if your email lands in your audience’s inbox at the wrong time, it may never get opened. So, when is the best time to send emails? Recent research by NP Digital, based on an analysis of 1.46 billion emails sent over the course of a year, has revealed some fascinating insights. Here’s what you need to know.

Why Timing Matters

Email open rates depend on when your audience is most active and receptive. Sending emails at the right time not only increases open rates but also improves click-throughs and conversions. While every audience is unique, the data reveals clear trends that can serve as a starting point for your email campaigns.

Optimal Email Times for Each Day

Monday

Morning emails are best at the start of the week between 9 AM and 12 PM. Avoid sending during evening hours.

Tuesday

The hottest window is 9 AM to 6 PM, but early mornings work well too.

Wednesday & Thursday

Midday is magic! Target 12 PM to 3 PM for the best results.

Friday

People are engaged 9 AM to 12 PM, but avoid sending later in the day as the weekend mindset kicks in.

Weekends

Weekends aren’t ideal, but if you must send emails, here are the best times:

• Saturday: Surprisingly, 9 AM to 3 PM sees a good uptick in engagement.
• Sunday: A prime opportunity, with 6 AM to 3 PM being the sweet spot.

Key Takeaways

• Mornings (9 AM to 12 PM) are effective on weekdays, especially Mondays and Fridays.
• Midday (12 PM to 3 PM) is the prime time for midweek emails (Wednesday, Thursday, and Saturday).
• Afternoons (6 AM to 3 PM) are best for Sundays.

How to Apply This Data

While these trends provide a solid foundation, it’s important to remember that every audience is different. Use these tips as a starting point, but don’t stop there:

1. A/B Test Your Campaigns: Experiment with different times to find what resonates best with your audience.
2. Segment Your Audience: Different groups may engage better at different times. Segment your list by timezone, demographics, or behaviour.
3. Analyse Your Results: Continuously track open rates, click-throughs, and conversions to refine your timing.
