In short: 10 am for professional services. 12 pm for eCommerce. 2 pm for software/SaaS.

Clearly, the best time to send emails depends a lot on your market. Based on our research, we found out the best time to send email is different depending on the industry.

According to Infusionsoft, emails are open the most between 8 am and 12 pm and 1 pm to 4 pm. Meanwhile, emails get most clicks when sent between 1 pm and 2 pm.

Email Performance By Hour

Sendinblue went even further and analyzed the data depending on the business industry. Every industry has its own best time to send emails.

Best Time To Send Email By Business

Intercom focuses more on B2B companies, and the data they collected shows the same results: emails sent between 9 am and 12 pm get the most clicks. That’s only understandable: it must be the time when people come to work and check emails first thing in the morning.

Messages Opened By Time Of Day

HubSpot that is also mostly focused on B2B, proves the point: the best time to send emails is 10 am to 12 pm.

Highest Email Opens

The main focus of Omnisend is eCommerce, and their data shows a completely different picture. According to Omnisend, the best hours for the highest open and click rates are 8 am and 1 pm.

What Is the Best Day to Send Emails?

In short: Tuesday or Wednesday.

Basically, on Monday people are too overwhelmed with emails that they might have gotten during the weekend. Besides, Monday is the day when they are planning their week ahead, having meetings, etc.

According to Infusionsoft, emails sent on Tuesday or Wednesday get the highest open and click rate.

Email Performance By Day

HubSpot that focuses on B2B agrees with this trend. However, if a high open rate is what you are after, Monday might also be the best day to send an email.

Send Emails By Day

Klaviyo’s data confirms that for the highest open and click rate, it’s best to send your email blast on Tuesday or Wednesday. However, Klaviyo adds an important note: if you have an online store, you should also take revenue per recipient into account. Which is at its highest on Monday and Thursday.

Revenue Per Recipient

For the highest revenue per recipient rate, consider sending your email campaign on Monday or Thursday.

Sendinblue analyzed what the best day is to send email campaigns depending on the business industry. Here’s what they found out.

  • Tuesday is best for professional services (B2B).
  • Wednesday is best for eCommerce, software/SaaS, and marketing services.
Weekly Email Open Volume

Omnisend, whose main focus is email marketing for eCommerce, tend to agree with the following fact: emails sent on Wednesday get the highest open rate. At the same time, they add that the highest click rate goes to emails sent on Sunday (!)

Campaigns Sent VS Click Rates For Weekdays

UPD Jun 05, 2019: We got a fresh update from our partner, Campaign Monitor. Based on their data:

1. The best day for the highest open rates: Thursday
2. The worst day for lowest click rates: Monday


You might feel puzzled or overwhelmed with all this contradictory data. So, when is it actually best to send out email campaigns?

The thing is, it depends. Things to consider here include your industry and other business factors, as well as the goals you are after. Clearly, if you can get an email to the top of your recipient’s inbox during the so-called golden hour (that we discussed above), it seriously increases your chances of it being open. However, sending emails at the right time is not the only factor you might want to consider. Up your chances of getting your recipient’s attention by crafting a catchy subject line or adding a GIF to your email.

My advice is: it’s best to test the data on your audience and analyze the results. But while you are getting your first email campaign out there, it does make sense to consider the data from fellow industries.
