The Importance of Timing in Email Marketing

Email marketing remains a cornerstone of digital marketing strategies, delivering a robust return on investment (ROI). However, the effectiveness of an email campaign isn’t solely dependent on the content and design; the timing plays a crucial role. Understanding when your target audience is most receptive to emails can mean the difference between a successful campaign and one that goes unnoticed.

Email marketing offers a unique opportunity to engage with your audience directly. When you send an email, you are essentially knocking on the doors of your recipients, hoping they will welcome you in. To increase the chances of being welcomed, it’s essential to choose the right time for your knock.

There’s no one-size-fits-all answer to the best time to send marketing emails. It varies depending on various factors, including your industry, audience, and even geographic location. To shed light on this topic, we’ll explore data-driven insights and expert opinions to help you find the optimal email sending times.

Data-Backed Insights

Several studies and surveys have delved into the best times to send marketing emails. While the results may not be universally applicable, they can serve as valuable guidelines for your email marketing efforts. Let’s delve into the data:

1. CoSchedule’s Findings

CoSchedule, a popular content marketing platform, conducted extensive research on the best time to send emails. They analyzed data from multiple sources to identify patterns in email engagement.

According to CoSchedule’s data, the best days to send marketing emails are Tuesday and Thursday. These midweek days tend to be less crowded with emails, making it more likely that your email will stand out in the recipient’s inbox.

Furthermore, the optimal time slots to send emails were identified as 10 AM, 8 PM, and 2 PM. The late evening and early morning slots are particularly interesting, as they catch people outside their regular working hours when they might have more time to engage with emails.

2. Mailshake’s Insights

Mailshake, a sales engagement platform, also conducted research to find the best time to send emails. Their data aligns with CoSchedule’s findings in some areas and offers additional insights.

Based on their studies, the best days to send emails are Tuesday and Thursday, mirroring CoSchedule’s conclusions. However, they suggest that Wednesday is also a strong performer. This overlap among multiple studies underscores the significance of midweek days in email marketing.

Mailshake’s data indicates that the most optimal time slots to send emails are between 10 AM and 11 AM and 2 PM and 3 PM. These time slots coincide with CoSchedule’s findings, emphasizing the importance of mid-morning and early afternoon for email engagement.

3. Study Discrepancies

While the studies conducted by CoSchedule and Mailshake offer valuable insights, it’s important to note that there are discrepancies in the findings, particularly regarding the evening time slots. CoSchedule highlights 8 PM as a prime sending time, while Mailshake does not mention late evening at all.

These discrepancies illustrate the need for businesses to conduct their own A/B testing and analyze their specific audience’s behavior. Your audience might have unique patterns that don’t align with the general trends identified in these studies.

The Role of Industry and Audience

While the studies provide valuable general insights, it’s important to consider the unique characteristics of your industry and audience. Different industries and demographics may respond differently to email marketing, so tailoring your approach is essential.

1. Industry

The type of industry you operate in can significantly influence the best time to send marketing emails. B2B (business-to-business) industries, for instance, might find that Tuesdays and Thursdays are ideal for reaching professionals during their workweek. In contrast, B2C (business-to-consumer) industries might see different patterns based on consumer behaviors.

Additionally, some industries, like retail or e-commerce, may experience variations in email engagement depending on the season. For example, sending emails during holiday seasons or special promotions might require different timing to capture the attention of consumers.

2. Audience

Understanding your audience’s behavior is paramount. Factors like age, location, and lifestyle play a significant role in determining when your emails are most likely to be opened. Here are some considerations to keep in mind:

  • Geographic Location

If your audience is spread across different time zones, you’ll need to segment your email lists and send emails at the appropriate local times. Failing to do so can result in your emails being overlooked because they arrived at an inconvenient hour.

  • Demographics

Consider the age and lifestyle of your audience. Young professionals may be more likely to engage with emails during their work hours, while retirees might have different patterns. A/B testing with segmented lists can help you determine the ideal timing for different demographics.

  • Mobile vs. Desktop

With the prevalence of mobile devices, people check their emails at various times throughout the day. Ensure that your emails are mobile-responsive and compatible with different devices, so your audience can engage with them whenever they have a moment.

The Impact of Mobile Devices

Mobile devices have revolutionized the way we access and engage with emails. With smartphones and tablets, email communication is no longer confined to traditional desktop hours. People now check their emails on the go, whether it’s during their morning commute, while waiting in line, or before going to bed.

This shift in email behavior makes it essential for marketers to create mobile-friendly email campaigns. Responsive design ensures that your emails display properly on various screen sizes and devices. When your emails look good and function well on mobile, you’re more likely to catch the eye of recipients who engage with their emails at unconventional times.

The Psychological Factors

While data-driven insights provide a strong foundation for determining the best time to send marketing emails, it’s also important to consider the psychological factors that influence email engagement. These factors can vary from person to person but are worth keeping in mind as you refine your email marketing strategy.

1. The Start of the Workday

Many people start their workday by checking their email. Sending your email early in the morning, around 8 AM to 9 AM, could catch their attention when their inbox is relatively empty. However, this timing might not work for those who prefer to dive right into their work tasks upon arriving at the office.

2. The Mid-Morning Break

The mid-morning break, around 10 AM, is another window of opportunity. People often take a moment to check their personal email or catch up on any messages they might have missed earlier.

3. Post-Lunch Lull

The period right after lunch, from 1 PM to 3 PM, can be a good time to send emails. People may be looking for a brief distraction or a change of pace before the afternoon work rush.

4. Evening Leisure

Sending emails in the early evening, from 6 PM to 8 PM, can be effective for reaching those who prefer to check their personal emails after their workday is done. However, as mentioned earlier, this time frame may not be universally effective, so A/B testing is crucial.

5. The Weekend Factor

The choice of sending emails on weekends largely depends on your target audience. For some industries, especially those related to leisure and entertainment, weekends might be an excellent opportunity to engage with recipients who have more free time.

Testing and Optimization

Given the diverse range of factors that influence email engagement, testing and optimization are essential in finding the best time to send marketing emails for your specific audience. Here are some key steps to guide your testing process:

1. A/B Testing

A/B testing, also known as split testing, involves sending two variations of your email to different segments of your audience to see which one performs better. When conducting A/B tests for timing, send one version of the email at one time and the other version at a different time. Pay attention to open rates, click-through rates, and conversion rates to determine which timing works best.

2. Segment Your Audience

Segment your email list based on different characteristics such as location, age, and past engagement. This allows you to tailor your email sending times to specific groups within your audience.

3. Track and Analyze Results

Use email marketing software to track and analyze the performance of your email campaigns. Monitor metrics like open rates, click-through rates, and conversion rates to evaluate the success of your emails at different times.

4. Iterate and Refine

Based on the results of your A/B tests and ongoing analysis, refine your email marketing strategy. Over time, you’ll develop a better understanding of when your audience is most receptive to your emails.


The best time to send marketing emails is not a one-size-fits-all proposition. While studies offer valuable insights, the unique characteristics of your industry and audience, along with shifting email behaviors, make it essential to conduct your own testing and analysis. By understanding your audience’s preferences and leveraging responsive design, you can increase the chances of your emails being opened, read, and acted upon.

Email marketing remains a powerful tool for connecting with your audience, and mastering the art of timing is an invaluable skill. Whether you choose to follow the general guidelines or fine-tune your approach through testing, always keep the recipient’s convenience and preferences at the forefront of your email marketing strategy. By doing so, you can maximize the impact of your email campaigns and achieve better results in your digital marketing efforts.
