The Best Time to Send Emails for Maximum Engagement

Timing Matters in Email Marketing

Email marketing is a powerful tool for businesses to connect with their audience, but timing is everything when it comes to getting the best open rates and engagement. Sending an email at the wrong time can mean the difference between a successful campaign and one that goes unnoticed.

A recent analysis by NP Digital examined 1.46 billion emails across 83 websites to determine the best time to send emails based on open rates. The data clearly indicates that emails sent between Tuesday and Thursday, particularly between 9 AM and 12 PM, perform the best.

In this guide, we’ll break down the best times to send emails, the reasoning behind these trends, and actionable strategies to optimize your email campaigns.

Why Email Timing Matters

Email marketing is all about delivering the right message at the right time. Sending an email when your audience is most likely to open it can increase engagement, drive conversions, and improve ROI.

Here’s why timing is critical:

• People check emails at predictable times – Most people check their emails first thing in the morning or during work breaks.
• Competing with inbox clutter – Your email is competing with dozens of others. Timing it right increases its chances of being seen.
• Industry-specific trends – Different industries have different optimal send times based on their target audience’s habits.

Best Days to Send Emails

1. Tuesday to Thursday: The Sweet Spot

According to the research, the best days to send emails are:

• Tuesday – Email open rates start picking up, with strong engagement throughout the day.
• Wednesday – Midweek emails tend to perform the best, with 9 AM to 12 PM being the optimal window.
• Thursday – Engagement remains high, making it the last strong day before the weekend slump.

Campaign Monitor confirms that midweek emails consistently achieve higher open and click-through rates.

2. Monday and Friday: Less Ideal but Still Viable

• Monday – Open rates are lower in the morning as people catch up on weekend emails. However, sending emails mid-morning (around 10 AM) can still yield decent results.
• Friday – As the weekend approaches, engagement starts to decline, but early morning emails can still perform well.

Worst Days to Send Emails

1. Weekends: Low Engagement

• Saturday & Sunday – The research shows that weekends have the lowest engagement rates. Most people are offline, spending time with family or engaged in leisure activities. Unless your audience specifically engages on weekends (e.g., B2C eCommerce promotions), it’s best to avoid sending emails on these days.

HubSpot’s research also supports this, showing that weekends consistently underperform in email marketing.

Best Times to Send Emails

1. Morning (9 AM – 12 PM): The Prime Window

The most effective time to send emails is between 9 AM and 12 PM, with peak engagement happening around 10 AM.

Why?

• People check emails after getting settled into work.
• It’s before meetings and lunch breaks, making it an ideal window for attention.

2. Early Afternoon (12 PM – 3 PM): The Secondary Window

Some audiences also check their emails during lunch breaks or right after. If your morning email doesn’t get opened, a follow-up in this window can still perform well.

3. Late Afternoon (3 PM – 6 PM): Lower Engagement

Engagement starts dropping as people wrap up work. However, for industries like eCommerce, this period can still work well.

4. Evening & Night (6 PM – 9 AM): Poor Performance

Most people are off work and either ignoring emails or delaying responses. Unless it’s a transactional email (like order confirmations), this period isn’t ideal.

Mailchimp’s email marketing study backs this up, showing that nighttime email open rates are significantly lower than daytime ones.

Actionable Strategies to Optimize Your Email Timing

1. Segment Your Audience

Not all audiences have the same habits. Use segmentation to tailor email timing based on user behavior.

For example:

• B2B professionals – Stick to work hours (9 AM – 12 PM, Tuesday – Thursday).
• Retail consumers – Test evenings and weekends for shopping deals.
• International audiences – Consider different time zones when scheduling emails.

2. A/B Test Send Times

Every audience is different. Run A/B tests by sending emails at different times and measuring open rates, click-through rates, and conversions.

3. Use Email Scheduling Tools

Platforms like Mailchimp, Klaviyo, and HubSpot allow you to schedule emails based on optimal engagement windows.

4. Resend Emails to Non-Openers

If an email isn’t opened within 24 hours, resend it at a different time to increase the chances of engagement.

5. Optimize for Mobile Users

Most emails are read on mobile devices. Ensure your emails:

• Have short subject lines (under 50 characters).
• Are mobile-friendly with clear formatting.
• Contain concise calls-to-action (CTAs).

Litmus’ research shows that up to 42% of emails are opened on mobile devices, making mobile optimization crucial.

Mastering Email Timing for Better Engagement

Effective email marketing requires strategic timing. By sending emails between Tuesday and Thursday, ideally between 9 AM and 12 PM, you maximize your chances of higher open rates and engagement.

Key Takeaways:

• Send emails Tuesday to Thursday, between 9 AM and 12 PM.
• Avoid weekends unless targeting B2C audiences.
• Use A/B testing to determine the best timing for your audience.
• Optimize emails for mobile users and schedule follow-ups for non-openers.

By implementing these strategies, you can ensure that your email campaigns are timely, relevant, and effective—helping you achieve better results and drive more conversions.
