Email best practices
If you’re an email marketer sending marketing emails to customers, you’ve probably already asked yourself this: What’s the best time to send my newsletter?
The time you schedule your emails determines how high your open rates and click-through rates (CTR) will be. And there are a lot of factors at play when deciding the best time and the best day of the week to send your emails.
Below, we’ll give you some tips on identifying the best days and times to send your newsletters and some recommendations to improve your overall email marketing strategy.
Let’s get straight to it. When should you be sending your email campaigns to get the most engagement? Most sources say you should send between 9 AM and 12 PM, but that’s a rather simplistic way to think about email send times.
The first thing to consider is that people check their email multiple times each day. In fact, according to our Email Engagement Report, 63.3% of users interact with their personal mailboxes at different points throughout the day.
Most people check their email multiple times of day.
It’s worth remembering, though, that just because somebody checks their email, it doesn’t mean they have the capacity to act on it, which means getting the time right is still key to driving good email engagement.
Generally, here’s how you can choose the optimal time to send your emails:
While this is some prescriptive guidance to get started, we wanted to take our research further an analyze the best times for email engagement – that is, opens and clicks.
That’s why our colleagues at Sinch Mailgun conducted a study to find the best time for email engagement based on the billions of emails sent by our customers. The graphs below represent email engagement by hour. In general, 15 UTC has the highest engagement in click-to-open ratios – that’s when most of this opens and clicks happened.
However, that doesn’t mean 3 PM is the best time to send in your country! Remember to convert UTC times to your own time zone to find the best time according to your region. For example, in the summer, 15:00 UTC translates to 11 AM for Eastern Standard Time.

Is it better to send newsletters first thing in the morning or late at night? That depends on where your users are located. In our Email Engagement Report, we discovered fundamental differences in email habits across different countries and cultures.
Open rates data across different cultures.
For example, our survey shows that if you want to reach German customers, then the early evening would be a good option of, with 57.8% opening emails at this time (compared to 19.4% in Spain). However, 27.4% of Spanish participants said they wait until the late evening before bed to check emails, but you’ll only get the attention of 9.1% of Germans if you send them your campaigns at that same time.
So, before blasting that email out across the World Wide Web, look at this data first. Take the time to segment your audience to achieve the best possible engagement in your target countries.
Your sending schedule largely depends on whether you’re a B2B or B2C brand and the industry you’re in – we’ll get to that later in this post.
But in all cases, data shows that there are some days to avoid sending your weekly newsletters if you want to achieve the highest open rates.
If we look back at the Sinch Mailgun study mentioned before, we can see that Tuesdays through Thursdays have the highest open rates. Open rates also followed suit, with midweek taking the lion’s share of campaign click rates.
While Tuesdays and Thursdays have slightly higher engagement rates, Wednesday is a solid second option. If you send emails twice a week within these days, however, make sure to pick a combination of Tuesdays and Thursdays. Sending emails on Tuesday and Wednesday, or Wednesday and Thursday, might make your customers feel overwhelmed and not read your emails at all in the process. Not good.
Fridays, while not the strongest day of the week for engagement, shouldn’t be completely disregarded either. People also get the most emails in the middle of the week. Maybe you might want to send your emails on another day of the week to have less competition in the inbox.
According to our research, Saturdays and Sundays are the worst days for email engagement. We’re busy going out socializing, seeing family, or doing errands. Emails are not going to be a priority, so as a rule of thumb, avoid the weekends. The exception to this rule is sending lighthearted content that’s more palatable on weekends.
However, if you had to choose, is it better to send an email on a Friday or a Monday? Traditionally, both Fridays and Mondays have been perceived as bad days to send emails. However, our research shows that Friday outperforms Monday significantly on open and click through rates. On Mondays, people are either planning out their week or are sifting through the weekend’s emails. And let’s be honest, we’re not the sharpest workers on Mondays.
At the end of the day, the best way to choose a day to send your email campaigns is to do some tests on your list. As a starting point, look at engagement data, past open rates, and click-through rates, and formulate a hypothesis based on past information.
No matter what, if you regularly send weekly promotional emails or newsletters, be sure to send them on the same day every week. This builds trust and anticipation as your audience will come to expect your content at that time.
During holidays or special events, don’t hesitate to send your newsletters at a later date or a different time. While consistency is important, it’s always preferable to send at a different time and get higher open rates, than to stick to your sending schedule and remain unopened.
As we’ve already mentioned, people don’t use their professional and personal inboxes in the same way or at the same time. Some people rarely use their personal email addresses, while others get notifications every time a new email comes in. Some professionals check business emails regularly, while others only do it during the workday or at fixed times.

To determine the best time to send your email blasts, you’ll need to ask yourself questions like:
Keep in mind that this distinction between B2B and B2C is very important, as users behave differently when using work or personal email accounts. If you have defined marketing personas, they will be very useful in understanding how your subscriber list engages with your emails.
You’ve worked so hard to create the content for your next campaign: You’ve come up with powerful copy, a catchy subject line, and great calls-to-action (CTAs)… And yet, why are your emails not being opened or clicked through? It might be that you’re not sending emails at the right time of day.
The email inbox is a crowded space. Emails at the top of the inbox generally get the best email engagement than those at the bottom, which explains why the sending time is so important when planning your key email marketing campaigns.
Sending your campaigns at the right time can help you:
The key takeaway here is that by understanding customer behavior, habits, and time zones you can better determine the best day and time of the week to send your campaigns, and ensure your message is seen first when your email subscribers check their inbox.
86.4% of respondents say having time to read an email is an important factor in determining whether to open it.
As we have already said, finding the time with the highest email engagement depends on many aspects – your business, customers, targets, newsletter type, and so forth. Age, habits, and time zones are important elements that will impact open rates.
Chances are, you already have a treasure chest of time-related data from your audience. Go to your email service provider’s statistics dashboard and select the day with the most activity. Then view the hourly breakdown and you’ll see exactly when your audience engages the most with your campaign.
Mailjet users can find engagement stats for their campaigns in our platform’s Statistics dashboard.
Ultimately, we encourage you to undertake A/B tests and analyze the data. If you want to figure out the peak time to send your weekly newsletter, you could do a test spanning three weeks: In the first week of the test, send your newsletter at 10 AM, then next week send it at 1 PM, and the week after try 9 PM.
You can also try A/B testing by sending a campaign to half of your list in the early morning and to the rest in the afternoon. Compare and analyze the results, and move on to the next experiment, just like in science class.
When it comes to finding the best time to send your email campaigns, there is no one-size-fits-all answer. The type of business you have, your customers, the type and number of emails you send, and your targets all determine your best schedule.
