Timing can make or break your email marketing campaign. Even the best content may fall flat if it lands in an inbox at the wrong moment. Knowing when is the best time to send marketing emails is key to maximizing opens, clicks, and conversions. As consumer habits evolve, staying up-to-date with the latest data is more important than ever.
In this article, we’ll explore the most recent insights from 2025 to help you identify optimal email send times so you can reach your audience when they’re most likely to engage.
The Significance of Email Timing
Timing is one of the most critical, yet often overlooked, factors in email marketing success. Whether you’re wondering what is the best time to send a marketing email or when is the best time to send email marketing, the answer can directly influence your results.
Impact on Open and Click-Through Rates
When an email hits the inbox can significantly affect whether it’s opened or ignored. Studies show that emails sent at peak times – when recipients are most active – tend to see much higher open and click-through rates. Understanding what time is best to send email marketing means aligning your send schedule with your audience’s daily habits.
Sending emails too early in the morning or late at night can bury them under a pile of messages. Conversely, reaching subscribers when they’re checking email, such as mid-morning or early afternoon, dramatically increases visibility and engagement.
Influence on Conversion Rates
Beyond opens and clicks, timing also affects conversion rates. If your email reaches someone when they’re primed to take action, like during a break or just before making a purchase decision, you’re more likely to see a positive outcome.
This is why so many marketers ask, “What is the best time to send email marketing?” or “When is the best time to send marketing emails?” The right answer varies by audience and industry, but applying data-backed timing strategies can lead to stronger engagement, more conversions, and ultimately, greater ROI.
Best Days To Send Marketing Emails
Choosing the right day to send your campaign is just as important as the time. If you’ve ever asked, “What is the best time to send a marketing email?” or “When is the best time to send email marketing?” Understanding the performance of different days of the week is a great place to start.
Tuesday
Research consistently ranks Tuesday as the top-performing day for email engagement. Open and click-through rates tend to peak mid-morning on Tuesdays, making it an ideal time to send promotional emails, newsletters, and product announcements. If you’re wondering what the best time to send email marketing is in terms of day of the week, Tuesday is a reliable choice for most industries.
Wednesday and Thursday
Mid-week emails, particularly those sent on Wednesday and Thursday, also show strong performance. These days, strike a balance. Recipients are usually settled into their workweek and more likely to check and engage with emails. They’re excellent choices for content-focused or follow-up campaigns.
Monday and Friday
Monday can be hit-or-miss. While some people catch up on emails at the start of the week, others may be overwhelmed with weekend backlog. Friday engagement can dip slightly as the weekend approaches, though morning sends may still perform well, especially for B2B and time-sensitive promotions.
Weekends
In general, weekend emails tend to underperform in terms of open and click rates. People are less likely to engage with marketing content while away from work. However, exceptions exist—especially for industries like e-commerce, events, or B2C entertainment, where consumers may be more active during their personal time.
So, what is the best time to send marketing emails in terms of days? Midweek, especially Tuesday through Thursday, offers the strongest engagement rates across most audiences, but always consider your specific industry and audience behavior.
Optimal Times To Send Marketing Emails
In addition to choosing the right day, timing your emails by the hour can significantly influence engagement. If you’ve been wondering what time is best to send email marketing or when is the best time to send marketing emails, the answer depends on your audience’s daily habits. Here’s a breakdown of the most effective time slots:
Morning (8 AM – 10 AM)
Morning is widely considered one of the best times to send email marketing campaigns. Many people check their inbox first thing at work or during their morning routine. Emails sent between 8 AM and 10 AM often see high open rates, especially for B2B audiences who are planning their day.
Midday (12 PM – 1 PM)
Lunchtime is another strong window for engagement. People often take a break around 12 PM to 1 PM, providing a short window to catch up on personal or non-urgent emails. Sending during this period can yield good results, particularly for newsletters or promotional offers.
Afternoon (2 PM – 4 PM)
The post-lunch lull can be a surprisingly effective time to send emails. Between 2 PM and 4 PM, many recipients are back at their desks but may be more inclined to check non-work messages as their productivity dips. This is a solid window for both B2B and B2C campaigns.
Evening (6 PM – 9 PM)
For B2C businesses, evening emails can perform well. From 6 PM to 9 PM, people are typically off work and more relaxed, often browsing on mobile devices. This time slot is especially effective for content like flash sales, product recommendations, or entertainment.
Late Night (After 10 PM)
Sending emails after 10 PM is riskier, as many recipients are offline or preparing for bed. However, this time slot may work for specific niches, such as night-shift workers or audiences in different time zones. While open rates tend to drop, competition in the inbox is lower, which can improve visibility.
Industry-Specific Email Timing Insights
While general timing benchmarks are helpful, the most effective email send times can vary significantly by industry. Understanding your audience’s habits is key to optimizing engagement. If you’ve been wondering what is the best time to send a marketing email in your specific field, here’s how timing differs across sectors.
B2B (Business-to-Business)
In the B2B space, professionals are most active during standard work hours. The best times to send email marketing in this sector are typically:
- Tuesday to Thursday
- Between 8 AM and 10 AM or 1 PM to 3 PM
These windows align with inbox-checking routines and quieter periods between meetings. If your goal is to boost open and reply rates for reports, whitepapers, or event invites, weekday mornings are ideal.
B2C (Business-to-Consumer)
For B2C marketers, timing is less rigid. Audiences tend to engage more during evenings and weekends, when they’re away from work and browsing on mobile devices. Ideal send times include:
- Weekdays: 6 PM – 9 PM
- Weekends: Late morning or early afternoon
This timing works well for content like promotions, lifestyle newsletters, and entertainment-focused emails. If you’re asking when is the best time to send email marketing to a general consumer audience, outside of work hours is often the answer.
E-commerce
E-commerce brands thrive on strategic promotional timing. Peak performance often comes:
- Tuesdays and Thursdays
- Morning (9 AM – 11 AM) or evening (7 PM – 9 PM)
Sending emails during shopping windows—before lunch breaks or after work, encourages immediate action. Timing flash sales, product drops, or cart abandonment reminders around these periods can significantly boost conversions.
SaaS and Tech
For SaaS companies, timing matters based on email type. Here’s what works best:
- Product updates and feature announcements: Send during weekday mornings, ideally between 9 AM – 11 AM, when users are focused on work.
- Onboarding and lifecycle emails: These perform well when timed with user activity triggers or set up in automated workflows.
In this context, what time is best to send email marketing depends on the user journey, timeliness and contextual relevance are more important than the day of the week.
Healthcare and Fitness
Audiences in the health and wellness space tend to engage with content during personal time:
- Early mornings (6 AM – 9 AM) before the workday begins
- Evenings (7 PM – 9 PM) after work or workouts
Email types include appointment reminders, wellness tips, and class schedules. Weekend mornings also see decent engagement. Knowing when is the best time to send marketing emails in this industry can increase participation and adherence.
Factors Influencing Optimal Email Send Times
There’s no one-size-fits-all answer to when is the best time to send marketing emails because optimal timing depends on who you’re sending to and how they engage. Understanding the unique behaviors and preferences of your audience helps refine your strategy and boost results.
Audience Demographics
Different age groups and professional roles interact with email differently. For example:
- Professionals and B2B audiences are more likely to check email during standard work hours.
- Younger, mobile-first audiences may respond better to emails sent in the evening or on weekends.
- Retired or stay-at-home audiences might engage more throughout the day.
If you’re considering what time is best to send email marketing to your specific demographic, analyze past engagement metrics to guide timing decisions.
Geographical Location and Time Zones
Sending an email at 10 AM might be perfect for one recipient, but too early or too late for another in a different time zone. Segmenting your list by location ensures your emails arrive at optimal local times. Many email marketing platforms allow time zone–based scheduling, making it easier to personalize delivery windows.
Device Usage Patterns
Whether your audience primarily checks email on mobile or desktop can also influence timing:
- Mobile users often engage during commutes, breaks, or evenings.
- Desktop users typically open emails during working hours.
Understanding how your audience reads your emails helps fine-tune not just send times, but also design and content formatting.
Email Frequency and Consistency
Even the best timing won’t deliver results if your emails are sporadic or overwhelming. Establishing a consistent sending schedule trains your audience to expect and engage with your content. Whether you email weekly, biweekly, or monthly, maintaining consistency helps build trust and familiarity, both critical for long-term success.
Leveraging Technology For Email Timing
As email marketing becomes more sophisticated, technology now plays a crucial role in determining when is the best time to send marketing emails. Modern platforms and AI-powered tools take the guesswork out of timing, making it easier than ever to reach subscribers when they’re most likely to engage.
Email Marketing Platforms
Many leading email marketing services, such as Mailchimp, Brevo, and Constant Contact, now include send-time optimization features. These tools analyze past user activity, like open and click behavior, to suggest or automate the best send times for each contact. If you’re looking for what is the best time to send email marketing campaigns, these built-in features offer a great starting point.
Artificial Intelligence and Machine Learning
AI and machine learning algorithms go a step further by continuously learning from subscriber behavior over time. These systems can:
- Predict peak engagement windows for each individual recipient
- Adjust send times dynamically based on historical patterns
- Personalize delivery without manual segmentation
By leveraging AI, marketers can dramatically increase open and click-through rates while saving time and improving relevance.
A/B Testing
If you’re unsure what works best for your specific audience, A/B testing is one of the most effective methods to find out. This involves:
- Sending the same email at two or more different times
- Comparing performance metrics (opens, clicks, conversions)
- Using data to refine future campaign timing
Consistent testing helps uncover unique engagement patterns and ensures that you’re not relying solely on generalized benchmarks.
Common Mistakes to Avoid
Even with access to data and tools, many email marketers still make timing-related mistakes that hinder performance. Avoiding these common pitfalls is essential when trying to determine what time is best to send email marketing campaigns that truly connect.
Ignoring Time Zones
One of the biggest missteps is sending emails at the same time to an entire list—without accounting for recipients’ local time zones. An 8 AM send in New York might hit inboxes at 5 AM in California or 1 PM in London. Failing to segment by geography reduces the chances of your emails being seen when they matter most. If you’re asking when is the best time to send marketing emails, time zone alignment should be your first consideration.
Overlooking Audience Behavior
Assuming a universal “best time” without studying your actual audience can lead to missed opportunities. Different demographics and industries behave differently: professionals, students, and shoppers all check email at different times. Neglecting to tailor send times to your audience’s specific habits can result in lower engagement, even if you’re following general benchmarks.
Neglecting to Test and Optimize
What worked last year, or even last month, might not work today. Many marketers skip ongoing A/B testing, leading to stagnation. Without testing different send times and analyzing results, you miss the chance to optimize performance based on real behavior. Remember: “what is the best time to send email marketing” is not a static answer, it’s an evolving one, unique to your audience.
Timing Is Everything
Finding the best time to send marketing emails isn’t about following a one-size-fits-all rule. It’s about using data, testing continuously, and understanding your audience’s unique behavior. While studies suggest that Tuesdays through Thursdays, especially in the morning or early afternoon, often perform well, your optimal send time may differ based on industry, audience, and campaign goals.
Whether you’re asking “what is the best time to send a marketing email” or exploring AI-powered tools for timing optimization, the key is to experiment, analyze, and adapt. With a data-driven approach, your emails can land at just the right moment and drive the engagement your business needs.
