The best time to send emails is the moment your audience is most likely to open and click — and that depends on your goal, your audience, and their time zone. Across millions of campaigns, mornings win opens and evenings win clicks. The best days of the week to send emails are Friday and Monday for opens, and Friday and Tuesday for clicks. Here is the direct answer, the data behind it, and how to find the right window for your own list.

The short answer

For most senders, the strongest windows look like this:

These windows come from MailerLite’s 2026 analysis of more than 2.1 million campaigns. On weekdays, open rates peak in the morning (8 AM to 11 AM local time) while click rates peak much later, between 8 PM and 9 PM — and the one moment opens and clicks align is Friday at around 6 PM. By day, Friday generates the highest average open rate (49.72%), closely followed by Monday (49.44%), while Friday also leads on clicks (8.09%), followed by Tuesday (7.84%).

One caveat that travels with every number here: MailerLite’s dataset covers 2,138,817 campaigns from senders in the US, UK, Australia, and Canada — not Africa. Treat it as a global starting point. Send in your audience’s local time zone, and A/B test against your own list to confirm.

Why timing matters in email marketing

Timing is not about convenience. It is about landing in the inbox when your reader is actually paying attention. Once you know how email marketing works, send time becomes the lever that decides whether a strong message is seen at all.

People check email for work, shopping, and personal reasons at different points in the day, and reaching them at the right moment lifts visibility and engagement.

The ceiling is real. According to MailerLite’s 2026 industry benchmarks, the average email open rate in 2025 was 43.46%, a slight increase on 2024’s 42.35%, with a median click-to-open rate of 6.81% across all campaigns. A well-timed send moves you toward the top of that range; a poorly timed one buries a good message under everything that arrived first.

One honest note on open rates. Privacy features in modern email apps increasingly obscure whether a message was truly opened, so open rate has become a less reliable metric than it once was. Use it as a directional signal and judge real interest by clicks.

The best days of the week to send emails

If you optimize for one metric at a time, the days split cleanly. Friday is the strongest single day, and Monday and Tuesday round out the top of the week.

Here is the day-by-day view:

These figures come from MailerLite’s US, UK, Australia, and Canada dataset, so use them as a benchmark and confirm the pattern with your own African audience.

The gap between the best and worst weekdays is narrow, so day-of-week is a nudge, not a magic switch. Clicks are the metric that ties to revenue, so if a campaign exists to drive action, weight your decision toward the click-strong days — Friday and Tuesday.

Running a smaller business? For entrepreneurs and SMBs, Thursday at 9 AM delivers the highest average open rate of the week (46.3%) in MailerLite’s data — a useful default if you send one campaign a week and want it seen.

Two day-specific questions come up a lot:

• Best time to email on Monday: Send in the morning, around 8 AM to 11 AM local time. Monday is one of the strongest days for opens (49.44%), just behind Friday.
• Best time to email on Thursday: Aim for 9 AM if you run a small business — that is the single best open window of the week for entrepreneurs and SMBs (46.3%).

The best time of day: opens vs clicks

The single most useful idea here is that opens and clicks peak at different times.

Opens cluster in the morning, around 8 AM to 11 AM local time, when people first clear their inboxes. Clicks come later, around 8 PM to 9 PM, when readers have time to act on what caught their eye earlier. The two only converge on Friday at roughly 6 PM.

So the right send time follows your campaign goal. Want eyes on an announcement or subject line? Send in the morning. Want clicks on an offer or a product link? An evening send often earns more action. Always measured in the recipient’s local time, not yours.

A decision framework, not a single magic number

There is no universal “best time” — there is the best time for your goal, your audience, and your geography. Run your choice through four questions.

Goal: Opens or clicks? Morning for opens, evening for clicks. Decide what the campaign is actually for before you pick an hour.

Audience: B2B inboxes are busiest during mid-week working hours. B2C audiences engage more in evenings and weekends. Match the rhythm of the people you serve.

Industry: E-commerce often sees strong evening and weekend engagement; professional services skew to mid-week mornings. Your category shifts the window.

Time zone: A single global send time reaches some readers at 3 AM. If your list spans Accra, Lagos, and Nairobi, no one hour is right for all of them, so segment by region and schedule for each audience’s local time. That is how the morning-opens and evening-clicks logic actually holds.

For a quick starting point, here is how the two broad audience types tend to split:

Treat these as starting points, not rules. The time windows are MailerLite’s open and click peaks; the day patterns follow how each audience tends to behave — so test them against your own list.

Send-time guidance by email type

Different emails serve different jobs, and each has its own timing logic.

Transactional emails (order confirmations, password resets, shipping updates) go out the instant the user acts. Speed is the whole point, and a delay erodes trust.

Promotional emails work best when they create urgency, so the best time to send marketing emails leans on momentum. Mid-week mornings catch consumers before the weekend rush, and early-in-the-day sends drive early clicks. High-intent shopping moments deserve their own schedule.

Newsletters are non-urgent by nature, so they suit calmer windows like mid-morning around 10 AM or mid-afternoon around 3 PM, when readers have a moment to actually read.

Optimize for mobile and automate the timing

A growing share of email is read on phones, often on the move. Younger audiences in particular check inboxes during commute windows. Mobile-friendly design, from responsive layouts to short subject lines and easy-to-read fonts, makes sure a well-timed send is also a well-received one.

Automation is where timing stops being guesswork. Behavior-triggered emails (an abandoned-cart nudge, a post-purchase follow-up, a re-engagement message) fire at the right moment for each individual rather than on a fixed clock. That is timing personalized to the reader, not the calendar.

Want to act on these windows automatically? Arkesel Email Marketing lets you build event-triggered automation flows and A/B test your campaigns against your own list, so the right moment is built into every send.

Find your own best time: segment and A/B test

The benchmarks above are a starting point. The best time to send emails to your list is the one your own data proves, and three habits turn general guidance into your numbers.

Segment your list. Group subscribers by region, behavior, and preference, then time each segment’s send to its own pattern. One schedule rarely fits everyone.

A/B test send times. Send the same campaign to comparable groups at different times and let the open and click rates decide. Repeat it across a few campaigns before you trust the result.

Watch the data. Track opens, clicks, and conversions over time. Your best window will shift as your audience grows, so treat send-time optimization as ongoing, not one-and-done.

This is the part that beats any benchmark: your own list, tested in your own time zone.

Timing only pays off if your message reaches the inbox in the first place, so it is worth knowing how to keep your emails out of the spam folder too.

Frequently asked questions

What is the best time of day to send an email?

For opens, weekday mornings around 8 AM to 11 AM in the recipient’s local time work best. For clicks, evenings around 8 PM to 9 PM tend to perform stronger. Pick the window that matches your goal and confirm it with your own list.

What are the best days of the week to send emails?

In MailerLite’s analysis of more than 2.1 million campaigns, Friday leads on both opens (49.72%) and clicks (8.09%), with Monday strong for opens and Tuesday strong for clicks. The differences between weekdays are modest, so test your audience before committing.

What is the best time to email on Monday or Thursday?

On Monday, send in the morning (8 AM to 11 AM local time) — it is one of the strongest days for opens, just behind Friday. On Thursday, 9 AM is the standout for smaller senders: for entrepreneurs and SMBs, Thursday at 9 AM delivers the highest average open rate of the week (46.3%).

Is it better to send emails in the morning or the evening?

It depends on what you want. Mornings win opens, evenings win clicks, and the two align only on Friday at around 6 PM. Send in the morning to be seen and in the evening to be clicked.

Does the best send time differ for opens vs clicks?

Yes. Opens peak in the morning (8 AM to 11 AM local time) while clicks peak in the evening (8 PM to 9 PM). Choose your send time around the metric that matters to the campaign.

How does the best send time change by time zone, audience, and industry?

Always schedule in the recipient’s local time, because a single global send reaches some readers in the middle of the night. B2B audiences engage mid-week during work hours, B2C audiences lean to evenings and weekends, and categories like e-commerce skew later, so segment and adapt rather than copy one fixed time. For African lists spanning several time zones, schedule per region rather than sending everyone at once.

Put the right timing into every send

The best time to send emails is not a single number. It is a decision shaped by your goal, your audience, and their time zone, then proven on your own list. Use mornings for opens, evenings for clicks, and A/B testing to lock in what works.
