Let’s figure out what they are. 

Factors Influencing the Best Time to Send Cold Emails

Determining the best time of the day to send cold emails isn’t a one-size-fits-all solution. Various factors influence this decision, each contributing to the likelihood of your email’s success.

Factors Influencing the Best Time to Send Cold Emails

Determining the best time of the day to send cold emails isn’t a one-size-fits-all solution. Various factors influence this decision, each contributing to the likelihood of your email’s success.

Here’s what they are: 

1. The recipient’s time zone

The time zone of your recipient plays a critical role in determining the best time to send cold emails. Sending an email without considering the recipient’s local time can lead to your email being overlooked or buried under new emails by the time they check their inbox. 

For instance, an email sent at 9 AM EST will reach someone at 6 AM in PST, which might not be an ideal time for the recipient to engage with new correspondence.  

If you’re a business operating globally, adapting your email campaigns to match the recipient’s time zone is crucial. 

You can then start segmenting your lists based on geographical location & time-zones to witness an exponential increase in both revenue & reply rates. 

2. The recipient’s industry 

Different industries have unique operational rhythms that can influence the best time to send cold emails. A professional in the finance industry might start their day earlier and check emails first thing in the morning, while creative industry professionals might have different email checking patterns. 

Understanding these industry-specific patterns helps you optimize the campaigns, and tailoring your email schedule to increase engagement. 

3. The recipient’s job role 

The job role of your recipient can greatly affect the best time to send cold emails. High-level executives, for example, might check their emails early in the morning, late in the evening, or outside of standard working hours, as their days are often filled with meetings. 

Conversely, mid-level managers or other staff might have more regular email-checking patterns. Understanding these differences in job roles is essential for personalizing your outreach strategy. 

Thus, personalizing your emails not just in content but also in timing, as per the recipient’s job role, can lead to better engagement rates. 

What are the best days to send cold emails? 

Identifying the best days to send cold emails is not an exact science, but certain patterns emerge over time, given that there are certain time slots & days which work better than others. Generally speaking; Tuesday, Wednesday & Thursday witness better engagement 

Generally, Tuesday, Wednesday, and Thursday see better engagement. A recent research by CIENCE underscores this, with the following statistics being the highlight: 

  • Monday: 15.98%
  • Tuesday: 20.84%
  • Wednesday: 23.07%
  • Thursday: 21.32%
  • Friday: 18.52%
  • Saturday: 0.03%
  • Sunday: 0.24%

Although Wednesday was the best day to send cold emails through the week, the performance was quite satisfactory even on Tuesday and Thursday; even though the weekend saw numbers drop massively.  

Mondays, being the start of the week, are often busy, making them less ideal for initial outreach but suitable for follow-ups. Conversely, Fridays see people winding down for the weekend, potentially affecting engagement. 

That being said, the numbers vary from one research to another, with a 2021 GetResponse analysis of 7 billion emails stating that there wasn’t much difference in engagement between emails sent on different days, even though the open rates were still higher than usual on Monday and Friday.

Best days to send cold emails: How to choose the correct day? 

Choosing the best day to send cold emails is not a very simple process, since it depends on a variety of factors. 

Before figuring out the best time to send cold emails, if you’re looking for an answer to the best day for the same, here’s what you need to consider: 

1. Understand your target audience

The foundation of any successful email marketing strategy is a deep understanding of your target audience. Different demographics have varying email checking habits. For instance, a B2B audience might be more likely to check emails during traditional working hours, while a B2C audience could have different patterns. 

It’s essential to align your email send days with the times your audience is most active and engaged. 

2. Know industry benchmarks 

When it comes to the best days to send cold emails, each industry has different norms. For example, the tech & IT industry might see more active email engagement, while the healthcare sector might have different peak times. 

So, how do you figure if your open rates are at par with the industry average? Simple, check your data against the industry benchmarks

Start off with a small goal (such as having higher or similar open rates as the industry standard) and then run multiple A/B tests to find the best time for sending cold emails that get opened. 

Once you have those insights, you’ll be able to choose the best time and day to send cold emails that generate impact. 

3. Analyzing Historical Data

Reviewing the performance of your past email campaigns can provide valuable insights on the variations in open rates, CTR, responses and the timing. 

It’s important to look for patterns across the open and response rates on different days of the week, since this historical data can be a goldmine for understanding when your emails have historically performed best, guiding future campaign scheduling. 

4. Consider work-week dynamics 

Understanding the typical workweek flow of your target audience is crucial. For many B2B sectors, the workweek dynamics mean that Tuesdays and Wednesdays might be the best days to send cold emails, as Mondays are often for planning and Fridays are winding down days. 

However, this can vary based on the specific work culture and dynamics of the industry you are targeting.

5. Avoid holidays and special events

Sending emails during holidays or significant events can significantly decrease their effectiveness.

People are less likely to check their emails during these periods, and even if they do, they might not be in the right frame of mind to engage with a cold email. 

It’s important to be aware of major holidays and events, both globally and specific to your target audience’s region or industry.

In addition to the above, the level of personalization desired and understanding the recipient’s needs becomes crucial. You also need to time your follow-ups well enough so as to land more replies to your outreach. 

When used effectively, they play a crucial role in optimizing your cold email campaigns for higher engagement and response rates.
