This article explains the best days and times to send emails, based on reliable data and recent trends. It also covers tools, tips, and strategies to help you find what works for your audience.

Why Email Timing Matters

When you send your email is just as important as what you send. Research from Campaign Monitor (2024) found that emails sent at the right time had up to 22% higher open rates and 45% more click-throughs. Why? Because people check emails during specific parts of their day. If your email lands when they’re not looking—or worse, when their inbox is already full—it may never be opened.

When Are People Most Likely to Open Emails?

According to studies from Campaign Monitor (2024), Mailchimp (2024), and GetResponse (2023), the best times to send marketing emails are:

Morning (9:00–11:00 a.m.)
Early afternoon (1:00–2:00 p.m.)

These are the windows when people are often settled into work, checking their inboxes, and making decisions.

A massive study by GetResponse (2023), which looked at over 7 billion emails worldwide, found that emails sent at 8 a.m., 1 p.m., and 4 p.m. had the highest engagement. Similarly, Mailchimp (2024) reported that emails scheduled for 10 a.m. local time across industries performed best.

The Best Days to Send Marketing Emails

Data from HubSpot (2024) and Moosend (2024) consistently ranks Tuesday, Wednesday, and Thursday as the best days to send emails. Monday emails often get lost in the catch-up rush, and Fridays tend to have lower engagement as people begin to switch off from work.

If your business serves consumers directly (B2C), weekends might work better. A study by Omnisend (2024) found that Saturday emails led to higher conversion rates, especially in e-commerce and retail, as people have more time to browse and shop.

Quick Recap:

Best days: Tuesday, Wednesday, Thursday
Best times: 9–11 a.m., 1–2 p.m.
Bonus: Try Saturday morning for B2C campaigns

Why These Times Work

People usually check their inboxes:

In the morning, after waking up or starting work
After lunch, during a mental break
During commutes, especially on mobile devices

By catching them at these moments, your email has a better chance of being read.

Time Zones Make a Big Difference

Sending an email at 10 a.m. Eastern Time might work for someone in New York—but not for a reader in London or Bangkok. This is where time zone optimization becomes key.

Modern email platforms like:

…offer features that send your email at 10 a.m. in each user’s local time. This gives every reader the best possible chance to see your message when they’re active.

Industry-Specific Email Timing Trends

Different industries show different behaviors. Here’s a data-backed breakdown from Mailmodo and HubSpot (2024):

Industry	Best Day	Best Time
B2B SaaS	Tuesday	10:00–11:00 a.m.
E-commerce	Saturday	9:00–10:00 a.m.
Education & Training	Wednesday	10:00–11:00 a.m.
Health & Wellness	Thursday	1:00–2:00 p.m.
Financial Services	Tuesday	8:00–10:00 a.m.

This shows why it’s important to test what works best for your niche and audience.

Don’t Forget About Mobile Users

According to Litmus (2025), over 60% of emails are opened on mobile devices. This means people read emails while commuting, relaxing at home, or waiting in line.

To reach mobile readers, consider sending emails:

Early morning (6:30–8:30 a.m.)
Evening (7:00–9:00 p.m.)

These times often see a second wave of engagement after the workday ends.

Use A/B Testing to Find the Best Time for Your List

Every email list behaves a little differently. That’s why it’s smart to test your timing. Most modern platforms let you run A/B tests where you send the same email at two different times and compare the results.

Tools like:

…help you experiment with send times and learn what your subscribers prefer.

How to Test Timing:

Split your list in half.
Send the same email at different times (e.g., 10 a.m. vs. 2 p.m.).
Compare open rates, click rates, and conversions.
Repeat weekly or monthly until you find your sweet spot.

Smart Send-Time Features

Some tools use AI to automatically choose the best send time for each contact based on their past behavior. For example:

These features save time and increase accuracy.

Real Case Study: Airbnb’s Email Timing Strategy

Airbnb used data to shift their campaign timing from mid-afternoon (3 p.m.) to morning (10 a.m.) based on users’ time zones. As a result, they reported:

+18% more opens
+27% more clicks
+20% more bookings
(Litmus, 2024)

This shows how small timing changes can lead to big wins.

Don’t Ignore Email Frequency

How often you send matters just as much as when you send. Klaviyo (2025) recommends:

1–2 emails per week for B2B audiences
2–3 emails per week for B2C or retail lists

Too many emails, and you risk high unsubscribe rates. Too few, and your audience may forget about you. Try to keep a consistent schedule, like every Tuesday morning or Thursday afternoon.

Extra Tips to Maximize Email Timing

Avoid Mondays and Fridays: Mondays are for catching up, and Fridays are for winding down.
Use re-sends: Send the same message again after 48–72 hours to those who didn’t open.
Track local holidays: A great time in one country might be a holiday in another.
Subject line still matters: Even perfectly timed emails won’t get opened without a strong subject.

Note

If you want more people to open and engage with your marketing emails, don’t overlook when you send them. Data shows that Tuesdays to Thursdays at 9–11 a.m. or 1–2 p.m. work best—but the real winner is what works for your audience.

Use A/B testing, time-zone sending, and smart tools to find your best timing. And remember: timing won’t fix a weak email. Make sure your content is helpful, your subject line is strong, and your design looks good on mobile.

Once you combine all of that with perfect timing, you’ll see your engagement—and your results—take off.
