The best time to send a cold email is usually Tuesday through Thursday morning in the prospect's local time zone. Recent B2B studies consistently point toward morning sending, although the exact winning day varies by dataset. Belkins' 2026 study of more than 7.5 million cold emails found that Wednesday and Thursday produced the highest weekday reply rates, while 8 AM to noon was the strongest time window.
Other recent datasets favor Tuesday, especially around 8 AM to 10 AM. A 2026 study of 500 B2B cold emails found Tuesday from 9 AM to 11 AM produced its strongest results, while another large-scale analysis identified 8 AM in the recipient's time zone as the strongest individual send time.
So there is no single magic minute that works for every campaign. A better starting point is Tuesday, Wednesday, or Thursday morning, adjusted to the recipient's local time, followed by testing against your own reply data.
What Is the Best Time to Send Cold Emails?
For most B2B campaigns, start with 8 AM to 11 AM in the recipient's local time zone.
Morning sends consistently perform well across recent cold email datasets. Belkins found that emails sent between 8 AM and noon generated the highest reply rate in its 2025 campaign data. Its study also found that early morning, from 5 AM to 8 AM, performed nearly as well.
CIENCE's analysis of 6 million outbound emails identified 8 AM in the recipient's time zone as its strongest individual sending time, with Wednesday producing the highest share of replies.
A practical starting schedule looks like this:
Send Window | Recommendation | Best Use |
7 AM–8 AM | Good | Early inbox placement |
8 AM–10 AM | Best starting point | First-touch cold emails |
10 AM–12 PM | Strong | First touches and follow-ups |
12 PM–2 PM | Test | Secondary window |
2 PM–5 PM | Weaker | Lower-priority sends |
After 5 PM | Usually avoid | Limited B2B use |
Late evening | Test only | Audience-specific campaigns |
These are starting points rather than universal rules. Your audience, industry, geography, job role, and campaign quality can change the result.
Which Day Is Best for Cold Email?
Tuesday, Wednesday, and Thursday are the safest days to test first.
Recent studies disagree slightly about which of those 3 days is number 1. Belkins' 2026 research found Wednesday and Thursday tied for the highest weekday reply rate. CIENCE found Wednesday strongest, while several 2026 practitioner datasets place Tuesday first.
That suggests a better strategy than obsessing over one day:
Tuesday: Strong first choice
Wednesday: Strongest according to several large datasets
Thursday: Strong alternative, particularly for follow-ups
Monday: Test selectively
Friday: Generally weaker
Saturday: Usually avoid for B2B
Sunday: Audience dependent
For a new campaign, Tuesday and Wednesday morning are good starting points. Then compare them with Thursday rather than assuming one day will always win.
Why Is Tuesday Morning Good for Cold Emails?
Tuesday morning gives prospects time to move past Monday's backlog while still leaving most of the working week ahead.
Monday can be crowded with internal meetings, weekend email accumulation, and weekly planning. Friday creates the opposite problem because prospects are often focused on finishing current work rather than starting a conversation with a new vendor.
That does not mean every Monday or Friday email will fail. It means those days may give a new cold email less attention than a well-timed midweek message.
One recent study of 500 B2B cold emails found Tuesday from 9 AM to 11 AM produced a 9.8% reply rate in its dataset, compared with 4.5% on Friday morning and 2% on Friday afternoon.
Is Wednesday the Best Day to Send Cold Emails?
Wednesday is one of the strongest days to test, but it is not universally the winner.
CIENCE's analysis of 6 million outbound emails found Wednesday generated the largest share of replies, while Belkins' 2026 study found Wednesday and Thursday tied for the highest weekday reply rate.
Other datasets have found Tuesday slightly ahead of Wednesday. That difference matters because cold email performance varies by audience and campaign.
Instead of treating Wednesday as a fixed rule, use it as one of your primary test days.
A simple test could be:
Tuesday at 9 AM
Wednesday at 9 AM
Thursday at 9 AM
Keep the audience quality, email copy, sending volume, and campaign conditions as similar as possible. Then compare positive reply rates.
What Is the Worst Time to Send Cold Emails?
For most B2B campaigns, Friday afternoon and weekends are poor starting points.
Friday afternoon is particularly difficult because prospects may be finishing weekly tasks, preparing for the following week, or simply paying less attention to new sales messages.
Belkins found Friday had the lowest weekday reply rate in its 2025 data. Another 2026 dataset found Friday afternoon to be its weakest window.
The main times to avoid when you have no audience-specific data are:
Friday after 2 PM
Saturday
Sunday for most B2B audiences
Late evening
Very early morning when the recipient is unlikely to check email
There are exceptions. For example, some audiences work weekends or have different schedules. Timing should follow the prospect's working pattern, not an arbitrary calendar rule.
Does Time Zone Matter for Cold Email?
Yes. Send according to the recipient's local time, not your own.
Suppose your sales team is in Pakistan and you're contacting prospects in New York, London, and Sydney. Sending everything at 9 AM Pakistan time means those prospects receive the emails at very different points in their workday.
Instead, schedule the campaign around each recipient's time zone.
For example:
Prospect Location | Target Send Time |
New York | 8–10 AM local |
London | 8–10 AM local |
Dubai | 8–10 AM local |
Sydney | 8–10 AM local |
This is particularly important for agencies running campaigns across multiple countries.
A 2026 timing study specifically recommends sending according to the prospect's local time rather than the sender's time zone.
What Is the Best Time to Send Cold Emails to Executives?
Executives can be harder to generalize because their schedules vary more than those of typical office-based prospects.
A useful starting point is early morning, around 8 AM to 10 AM local time. This gives the email a chance to appear while the prospect is reviewing priorities before meetings take over the day.
However, executives may also check email outside conventional working hours. That makes testing more important.
You can test:
7:30 AM
8:30 AM
9:30 AM
10:30 AM
Keep the message and audience similar and compare positive replies and meetings, rather than simply measuring total replies.
What Is the Best Time to Send Cold Emails to Salespeople?
Salespeople spend much of the day in calls, meetings, prospecting sessions, and CRM tasks.
For that reason, early morning can be worth testing before calendars become crowded.
Start with:
Tuesday to Thursday, 8 AM to 10 AM local time.
A secondary test window is around 1 PM to 2 PM, when some prospects may have a gap between meetings.
Don't assume the afternoon will perform equally well. Belkins' 2026 study found afternoon sends produced lower reply and meeting rates than morning sends.
What Is the Best Time to Send Cold Emails to Founders?
Founders often have less predictable schedules than employees at larger companies.
They may answer email early in the morning, late at night, or between meetings. That makes a single universal send time less reliable.
For a starting test, use:
Tuesday or Wednesday between 7:30 AM and 9:30 AM local time.
Then test a second window that fits the founder's likely schedule.
For example, you could compare early morning against early afternoon. If the campaign targets founders in a specific industry, use your own reply data to determine which window produces better conversations.
Is Morning Better Than Afternoon for Cold Email?
Recent data generally supports morning sending.
Belkins' 2026 study found emails sent between 8 AM and noon produced a 0.54% reply rate, compared with 0.47% from noon to 5 PM. Its meeting-rate data showed an even larger difference, with morning sends producing a 0.4% meeting rate compared with 0.1% in the afternoon.
That makes morning a sensible default.
However, don't confuse correlation with a guarantee. The quality of your list, offer, copy, sender reputation, and targeting can have a much larger effect than moving an email from 1 PM to 9 AM.
Recent cold email research also emphasizes that send time is a secondary optimization rather than a replacement for good targeting and messaging.
Should You Send Cold Emails on Monday?
You can, but Monday is usually not the first day I'd choose for a new campaign.
Prospects often start Monday by dealing with accumulated email, internal meetings, weekly planning, and existing priorities. A new sales email can become part of that backlog.
Monday can still work for:
Follow-up emails
Time-sensitive offers
Industries that operate heavily on Mondays
Prospects with known Monday availability
Campaigns where your own data shows strong Monday performance
For a first-touch campaign without historical data, Tuesday through Thursday is a better starting range.
Should You Send Cold Emails on Friday?
Friday morning can still produce replies, but Friday afternoon is usually a weaker choice.
Belkins' 2026 data placed Friday below the other standard weekdays for reply rate, while other recent datasets also show a decline later in the week.
If you need to send on Friday, test the morning first.
Avoid treating Friday as automatically useless. Some industries operate heavily on Fridays, and certain audiences may have fewer meetings than they do earlier in the week.
Should You Send Cold Emails on Weekends?
For most B2B campaigns, no.
Saturday and Sunday generally aren't the best starting points for business outreach. Belkins' data showed Saturday below the standard working days, although its Sunday result was unusually high because the volume was very small. Belkins specifically cautioned against treating that Sunday result as a general recommendation.
There are exceptions for industries where weekend work is normal.
For example:
Hospitality
Restaurants
Healthcare
Entertainment
Retail
Certain founder-led businesses
International teams
The recipient's actual working schedule matters more than a generic weekday rule.
What Is the Best Time to Send Cold Email Follow-Ups?
Follow-ups can generally use the same morning windows as first-touch emails.
A practical schedule is:
First email: Tuesday at 8–10 AM
First follow-up: Wednesday or Thursday morning
Second follow-up: The following Tuesday or Wednesday morning
Later follow-up: Test another weekday morning
Don't send every follow-up at exactly the same hour.
More importantly, don't make timing the only difference between follow-ups. Each message should provide a reason to continue the conversation rather than simply repeating the original email.
This is where a well-built cold email sequence becomes more useful than repeatedly changing the send time.
Should You Send Cold Emails at 8 AM or 9 AM?
Both are worth testing.
8 AM has strong support from large-scale research. CIENCE found 8 AM in the recipient's local time to be its strongest individual time, while Belkins found the broader 8 AM to noon period performed best.
However, there is no reason to assume 8 AM will always beat 9 AM.
For example, test:
Test | Send Time |
A | 8:00 AM |
B | 9:00 AM |
C | 10:00 AM |
Keep everything else as consistent as possible.
This gives you campaign-specific evidence instead of relying entirely on industry averages.
Does Sending at an Exact Minute Matter?
It can be worth testing, but don't make it a major priority.
Some recent practitioners recommend avoiding heavily crowded round-hour slots such as exactly 9:00 AM or 10:00 AM.
For example, you could schedule sends at:
8:17 AM
8:43 AM
9:12 AM
9:37 AM
The idea is to distribute sending rather than placing every message into the same minute.
Still, this is a secondary test. A better email sent at 9:00 AM will usually matter more than a mediocre email sent at 8:43 AM.
Does Send Time Affect Cold Email Deliverability?
Send time and deliverability are related, but they are not the same thing.
Timing determines when the email reaches the recipient. Deliverability determines whether the message can successfully reach the intended mailbox and how receiving systems treat it.
Your cold email deliverability depends on factors such as:
SPF, DKIM, and DMARC authentication
Sender reputation
Domain reputation
Email infrastructure
List quality
Bounce rates
Sending volume
Recipient engagement
Message content
Changing the sending time cannot repair a poor sender reputation or an invalid prospect list.
That is why send-time testing should come after the basic technical and list-quality issues have been addressed.
Does Sending Time Matter More Than Personalization?
No.
Timing can influence performance, but it cannot make an irrelevant email relevant.
If the prospect has no reason to care about your offer, sending the email at 8 AM instead of 2 PM won't fix the underlying problem.
A stronger order of priorities is:
Target the right prospects.
Write a relevant message.
Verify the recipient list.
Maintain healthy sending infrastructure.
Authenticate your domains.
Test the email.
Then test send timing.
Your cold email personalization strategy should therefore come before obsessing over the exact send minute.
How Should Agencies Test the Best Time to Send Cold Emails?
Agencies should avoid changing several variables at once.
Suppose you send one campaign Tuesday morning and another Friday afternoon with completely different audiences and messaging. You won't know whether the result came from timing, targeting, copy, or list quality.
A cleaner test looks like this:
Step 1: Choose a similar audience
Use comparable prospects with similar job titles, industries, company sizes, and locations.
Step 2: Keep the email consistent
Use the same offer, subject line, CTA, and personalization structure.
Step 3: Test different days
Start with:
Tuesday
Wednesday
Thursday
Step 4: Test different time windows
Try:
8–9 AM
9–10 AM
10–11 AM
Step 5: Send according to local time
Don't compare 9 AM Pakistan time with 9 AM New York time.
Step 6: Measure meaningful outcomes
Track:
Delivery rate
Bounce rate
Reply rate
Positive reply rate
Meeting rate
Conversion rate
Positive replies and booked meetings are generally more useful than raw opens.
How Long Should You Test Cold Email Send Times?
Don't decide on a handful of emails.
Run each test long enough to collect a meaningful number of sends and replies. The exact sample size depends on your campaign volume and baseline response rate.
For agencies, a practical approach is to test the same audience segment across several campaign batches rather than changing the schedule every day.
For example:
Week 1: Tuesday 9 AM
Week 2: Wednesday 9 AM
Week 3: Thursday 9 AM
Week 4: Repeat the strongest 2 windows
This helps determine whether an apparent winner was a genuine pattern or simply a small-sample result.
What Is the Best Cold Email Sending Schedule?
If you need a simple starting schedule without historical campaign data, use this:
Day | First-Touch Window | Recommendation |
Monday | 8–11 AM | Test selectively |
Tuesday | 8–10 AM | Strong first choice |
Wednesday | 8–10 AM | Strong first choice |
Thursday | 8–11 AM | Strong alternative |
Friday | 8–11 AM | Test morning only |
Saturday | Any | Usually avoid |
Sunday | Any | Usually avoid for B2B |
Send each email according to the recipient's local time zone.
This schedule reflects the strongest common pattern across recent research, while acknowledging that different datasets produce slightly different day-level winners.
What Other Factors Affect Cold Email Reply Rates?
Send time is only one part of the campaign.
A prospect is more likely to reply when the email reaches the right person, addresses a relevant problem, and makes the next step easy.
Other important factors include:
List quality
Invalid or poorly targeted contacts can increase bounces and reduce campaign performance.
Personalization
Relevant company, role, industry, or business context can make an email more useful to the recipient.
Subject line
The subject line should accurately represent the message without relying on misleading wording.
Offer
The prospect needs a reasonable reason to respond.
Call to action
A simple question is often easier to answer than a complicated request.
Sending infrastructure
Healthy domains, authentication, reputation, and appropriate sending practices form the technical foundation of outbound email.
Follow-ups
Many prospects won't respond to the first email. A thoughtful cold email follow-up sequence gives the prospect additional opportunities to engage.
What Is the Best Time to Send Cold Emails for More Replies?
For most B2B campaigns, start with Tuesday, Wednesday, or Thursday between 8 AM and 11 AM in the recipient's local time zone.
If you want one starting point, try Tuesday at 9 AM local time. If you want to follow the strongest findings from large recent datasets, test Wednesday morning as well. Recent studies disagree about whether Tuesday or Wednesday is the single best day, but they consistently point toward midweek mornings as a strong starting window.
The important part is not finding a magical send time. It is testing timing while keeping your targeting, copy, sending infrastructure, and campaign conditions under control.
A good send time can help a strong campaign. It cannot rescue a weak one.
What is the best day to send cold emails?
Tuesday, Wednesday, and Thursday are generally the strongest days to test for B2B cold email. Recent studies differ on the exact winner, so testing these 3 days against your own audience is more reliable than following one fixed rule.
What is the best time to send cold emails?
8 AM to 11 AM in the recipient's local time is a strong starting window. Large recent datasets have consistently found morning sends outperforming afternoon and evening windows.
Is 9 AM a good time to send cold emails?
Yes. 9 AM is a practical starting point because it falls inside the strongest morning window identified by several recent studies. Test it against 8 AM and 10 AM to find the best result for your audience.
Should I send cold emails on Monday?
Yes, you can, but Tuesday through Thursday is usually a better starting point for first-touch B2B outreach. Monday inboxes can be crowded with weekend backlog and internal priorities.
Should I send cold emails on Friday?
Yes, but prioritize the morning if you need to send on Friday. Friday afternoon is generally weaker for B2B outreach because prospects are more likely to be focused on finishing the week.
Should I send cold emails on weekends?
No, not for most B2B campaigns. Weekend sending generally underperforms standard working days, although industries with weekend work can behave differently.
Should cold emails be sent according to the recipient's time zone?
Yes. Schedule the email according to the prospect's local time rather than your team's time zone. This is especially important for international and multi-region campaigns.
Does send time guarantee more replies?
No. Timing can influence engagement, but targeting, personalization, copy, list quality, sender reputation, and deliverability usually matter more than finding one perfect sending hour.
What time should I send cold email follow-ups?
Morning is a good starting point for follow-ups too. Test Tuesday through Thursday between 8 AM and 11 AM local time, while varying the actual day across your sequence.
Is morning better than afternoon for cold emails?
Yes, recent B2B data generally favors morning sending. Belkins' 2026 study found 8 AM to noon produced the strongest reply and meeting rates among its time windows.
How should I test cold email send times?
Keep your audience, copy, offer, and sending conditions similar while testing different days and time windows. Track positive replies and meetings rather than relying only on open rates.
