Posted by MISC CREW on on 28th Jun 2023

In the highly competitive world of eCommerce, email marketing continues to be a powerful tool to engage with customers, promote products & drive sales. However, the effectiveness of email marketing heavily relies on not only the content but also the timing. So, what is the best time to send your promotional emails?

After analyzing multiple research studies from renowned email service providers like Salesforce Marketing Cloud, Omnisend, HubSpot & others, we've gathered some compelling insights to help optimize the timing of your emails in 2024.

Best Days to Send Emails

According to these studies, the top three days to send emails in 2023 are Thursday, Tuesday, and Wednesday.

  1. Thursday
  2. Tuesday
  3. Wednesday

It's worth noting that Saturday and Sunday are the least effective days for sending emails. While some studies mentioned high open rates on these days, they are also the days when the fewest emails are sent, meaning the actual number of emails opened is significantly lower

Best Times to Send Emails

The studies also revealed the best times of the day to send emails:

  1. 10:00 am Local Time
  2. 09:00 am Local Time
  3. 08:00 am Local Time
  4. 01:00 pm Local Time
  5. 03:00 pm Local Time

However, the worst times to send emails are between 7 p.m. and 2 a.m. None of the studies reported high engagement rates during the evening and early morning.

Customizing by Time Zone

It's crucial to keep in mind that these times are typically given in local time for the recipients. You should adjust the sending time based on the time zone most of your recipients are in. If your recipients are spread across multiple time zones, consider segmenting your audience by time zone and sending your emails at the optimal time for each segment.

Final Thoughts

While these findings provide a general guide for optimizing email send times, it's essential to remember that every audience is unique. Regular testing and analysis of your email campaigns' performance are key to understanding your audience's specific behavior and preferences.


In 2023, the best days to send promotional emails are Thursday, Tuesday, and Wednesday, while the best times are 10 a.m., 9 a.m., 8 a.m., 1 p.m., and 3 p.m. local time for the recipients. However, audience behaviors can vary, so regular testing and analysis are recommended to identify the optimal email send times for your specific audience.
