Best Time to Send Email: A Data-Backed Guide for 2025

Email marketing has evolved, but one question remains key:
“What’s the best time to send email?”

Whether you’re launching a product, nurturing leads, or running a flash sale, when you hit “send” can often be as critical as what you send. This guide explores the best time to send email for maximum open rates and click-throughs, with practical tips tailored for marketers in 2025.

⏰ Why Email Timing Still Matters (Yes, Even in 2025)

You may think that with smart segmentation and AI-powered automation, timing no longer matters. Not quite.

Here’s why finding the best time to send email is still crucial:

  • Inbox competition is fierce – Your email is one of many in the inbox. Sending during peak engagement windows boosts the odds of being opened before it’s buried.
  • User behavior is habit-driven – People check emails in rhythm: mornings, lunch breaks, or before logging off.
  • Email clients track engagement history – Consistently sending emails when users engage most can improve long-term deliverability.

In short, even the most compelling content sent at the wrong time is a missed opportunity.

🕐 Best Time of Day to Send Email

Studies and email marketing benchmarks consistently reveal two peak time slots for higher engagement:

Morning Peak (9:00 AM – 11:00 AM)
Perfect send time, as professionals settle in and check inboxes for updates and insights.

Midday Window (1:00 PM – 3:00 PM)
Post-lunch hours often spark another engagement surge. Ideal for promotional emails and B2C product announcements.

💡 Tip: These are averages, not absolutes. For example:

  • SaaS audiences may respond better to earlier morning sends.
  • Evenings and weekends are prime time for e-commerce shoppers to browse and buy.

📅 Best Day of the Week to Send Email

Performance by day varies, but research shows these trends:
