You’ve spent time crafting the perfect email with an engaging subject line, compelling content, and a strong CTA, but if you send it at the wrong time, it may never get read. Timing plays a critical role in email marketing success, and sending at the right moment can dramatically boost open rates and conversions. But what works for one audience might not work for another. Whether you’re targeting businesses, consumers, or startups, understanding the best times to send emails is essential. This guide breaks down optimal sending times for different audiences, the impact of time zones, and how to refine your strategy with A/B testing.
Why Email Timing Matters
Email timing influences open rates, click-through rates, and overall engagement. If your email lands in an inbox at a time when recipients are busy or not checking emails, it’s likely to get buried.
On the other hand, sending an email when your audience is most receptive ensures better visibility and engagement. Factors like audience behavior, industry norms, and geographic location all contribute to finding the best email-sending times.
The Best Email Sending Times by Audience
Different audiences have different habits when it comes to checking emails. Effective email segmentation helps you understand these habits better. Let’s look at the optimal sending times based on various segments.
1. B2B (Business-to-Business) Audiences
Professionals and corporate employees rely on email for communication, making their inboxes highly active during standard work hours. However, they also receive a high volume of emails, so timing is crucial to avoid getting lost in the shuffle.
Best Days: Tuesday, Wednesday, and Thursday
Best Time Slots:
- 8:00 AM – 10:00 AM: Many professionals begin their day by checking emails before diving into meetings and tasks.
- 1:00 PM – 3:00 PM: Lunch breaks or post-lunch downtimes provide opportunities to check and respond to emails.
- 4:00 PM – 6:00 PM: Toward the end of the workday, professionals often catch up on emails before logging off.
Key Considerations:
- Avoid Mondays, as inboxes are flooded from the weekend, reducing the chance of engagement.
- Fridays see lower response rates as professionals prepare for the weekend and deprioritize emails.
- Industry-specific factors can play a role. For example, finance and healthcare professionals may have different peak email activity times.
2. B2C (Business-to-Consumer) Audiences
Consumers engage with emails differently based on lifestyle, habits, and shopping behaviors. Many check emails while on the go, using mobile devices, making timing a crucial factor in engagement.
Best Days: Tuesday, Thursday, and Sunday
Best Time Slots:
- 6:00 AM – 8:00 AM: Early risers and commuters check emails first thing in the morning, often on mobile.
- 12:00 PM – 2:00 PM: Lunch breaks are a prime time for checking emails and shopping online.
- 7:00 PM – 10:00 PM: Consumers relax in the evening, browsing emails on their phones or laptops.
Key Considerations:
- Weekend emails work well for leisure-focused industries like travel, entertainment, and lifestyle brands.
- Avoid sending emails too late at night, as they may be ignored or forgotten by the next morning.
- Promotional emails and limited-time offers often perform best in the evening when consumers have time to browse.
3. Small Businesses & Startups
Small business owners and startup founders often have unpredictable schedules, making it important to test different send times. Unlike corporate employees, they may check emails outside of traditional work hours.
Best Days: Monday through Thursday
Best Time Slots:
- 7:00 AM – 9:00 AM: Many entrepreneurs and decision-makers start their day early and check emails before meetings.
- 11:00 AM – 1:00 PM: Mid-morning to lunchtime is often a time for catching up on emails.
- 6:00 PM – 8:00 PM: Business owners may review emails in the evening after dealing with daily operations.
Key Considerations:
- Weekends can be effective for startups engaged in networking or community-driven promotions.
- Small business owners often multitask, so ensuring your email has a clear and actionable CTA increases response rates.
- Testing different days of the week can be valuable, as entrepreneurs may work outside standard business hours.
4. Marketers & Digital Professionals
Marketers receive a high volume of emails daily, so it’s essential to avoid getting lost in the clutter. Strategic timing ensures that your emails stand out and encourage engagement.
Best Days: Tuesday and Thursday
Best Time Slots:
- 9:00 AM – 11:00 AM: Peak productivity hours when marketers review emails for updates, insights, and industry news.
- 2:00 PM – 4:00 PM: Afternoon lulls make this a good time for engagement, especially for thought leadership content.
Key Considerations:
- Mondays often see slower response times as professionals prioritize internal meetings and urgent tasks from the previous week, making it harder for marketing emails to stand out.
- Fridays can be unpredictable, as some professionals wrap up work early while others rush to complete pending tasks, leading to inconsistent engagement levels.
- External factors like seasonality, industry events, and product release cycles can influence email effectiveness, so aligning your send times with audience behavior and key business moments can improve results.
To avoid memorizing all these numbers, here is your visual guide: the Email Timing Playbook. It compiles key recommendations on days and times for B2B and B2C audiences, as well as universal rules that always work.
The Impact of Time Zones on Email Effectiveness
When emailing a geographically diverse audience, sending at a fixed time can result in some recipients receiving emails outside their peak engagement hours. To ensure maximum reach and effectiveness, consider these strategies:
- Segment by time zone: Use automation tools to schedule emails based on the recipient’s location, ensuring they receive them at the most effective time.
- Adjust for peak hours: Research industry benchmarks for email engagement in different regions and adjust accordingly.
- Test staggered sends: Send emails at different times across various time zones and analyze performance data to determine the most effective timing for each region.
How to Use A/B Testing to Determine the Best Sending Time
Every audience behaves differently, so A/B testing is essential for refining email timing. Here’s how to do it:
- Test One Variable at a Time: Keep all elements the same except the send time to isolate the impact.
- Choose Two Time Slots: Select two different times based on industry benchmarks (e.g., 9 AM vs. 3 PM).
- Split Your List: Divide your email list randomly so each segment receives emails at different times.
- Measure Key Metrics: Compare open rates, click-through rates, and conversions.
- Optimize Based on Results: Choose the time that consistently performs better and refine from there.
Additional Tips for Optimizing Email Send Times
Beyond general best practices, consider these additional strategies:
- Analyze Your Own Data: Use email analytics to track when your subscribers engage the most, rather than relying solely on general industry benchmarks.
- Leverage AI & Automation: Many email platforms now offer AI-driven send-time optimization, automatically delivering emails when each subscriber is most likely to engage.
- Consider Mobile vs. Desktop Usage: Mobile users are more active in the early morning and late evening, while desktop users engage more during standard business hours.
- Use Resend Strategies: If an email isn’t opened, try resending it at a different time with a revamped subject line to increase engagement.
Final Thoughts
The bottom line is that timing is a powerful factor in email marketing success. While industry benchmarks provide a useful starting point, the best approach is to test and refine based on your unique audience. Understanding your recipient’s habits, time zones, and engagement trends allows you to significantly boost email performance. Whether you’re targeting B2B professionals, B2C consumers, small businesses, or marketers, optimizing send times ensures your message is seen, opened, and acted upon. So, fine-tune your strategy today and turn every email into an opportunity for real results!

What is the best time to send an email?
The best time depends on your audience:
- B2B: Tuesday–Thursday, 8:00 AM – 10:00 AM (local time).
- B2C: Tuesday, Thursday, or Sunday, 6:00 AM – 8:00 AM or 7:00 PM – 10:00 PM.

Use A/B testing to find the optimal time for your specific audience.
Why is Tuesday the best day to send emails?
By Tuesday, people are past Monday’s chaos but not yet winding down for the weekend. Inboxes are less crowded, and engagement is higher. Research shows open rates on Tuesdays are up to 15% higher than on Mondays.
Should I adjust email send times for different time zones?
Yes. If your audience is global, sending at a fixed time may mean some get your email at midnight. Use time-zone-based scheduling to deliver emails at 8:00 AM local time. This can boost open rates by 25% or more.
How can I test the best time to send emails?
Run an A/B test:
- Split your list in two.
- Send the same email at two different times (e.g., 9:00 AM vs. 3:00 PM).
- Compare open rates and clicks.
Repeat 3–5 times, then scale the winning time.
