At AtomPark Software, we don’t only develop mass email marketing solutions but also send newsletters to our subscribers, so the problem of mailing time is highly important for us too.

That’s why we’ve put together this guide to “the best time for sending email newsletters”. In this article, we will share with you our analysis of expert opinions, existing examples, and tools that will help you to define the best day and time for sending your email campaigns.

What influences the time of sending bulk emails?

The most important aspect in sending a newsletter is whether the message will be noticed and opened or not. This is a crucial factor for the other metrics and the success of the campaign — will your efforts be in vain or not?

There are several factors that influence the choice of the optimal time of mass mailing. You should consider them when scheduling the time of your email campaigns:

sponsored message

  • the geographical position of your subscribers,
  • their culture timing specific (eg. work days & hours)
  • online behavior,
  • the specifics of your business.

According to the chronological principle of mailbox sorting, your newsletter will be on the top of the inbox or on the bottom — a place in the top increases the chances of the newsletter being opened by the recipient. The lower your newsletter in the inbox list — the greater its chances of being lost.

When to start a bulk email campaign: Follow the sun tactics

Do you have a super system that automatically sends emails based on the user’s online activity? We don’t.

That’s why we choose the “following the sun tactics”.

This means that the basis for the countdown of mass mailing should be the time when the sun rises in its geographic location.

Time and Date

It is important if your email list has IP addresses of people from different countries and time zones.

The best variant is to send in the quiet minutes, such as:

What time to choose: stand out or go the trodden path?

How great it would be to remove all the guesswork and get the exact answer!

After analyzing popular studies, we have defined the top moments to start mass mailing your campaigns:

6:00 — 9:00 am
relaxed morning Breakfast, the way to the job — free minutes to check the mail
10:00 am — 12:00 pm
people have coped with the preparation for the working day and are ready to read your emails
02:00 — 03:00 pm

    • disadvantages — high competition rate, a newsletter has fewer chances of being open and read.
  2. Send at a time when no one does
    • advantages — more chances that your email will be noticed and read
    • disadvantages — most often, people are sleeping or busy at this time

According to Yesware’s analysis if you want to get a response from the person, it’s better to send an email campaign in the early morning or evening:

What day is the best for sending emails?

So, we figured out the perfect sending time, what about the perfect day?

Let’s start with what day is the most popular for sending newsletters among marketers.

This GetResponse survey says that the top sending day among email marketers is Tuesday and Thursday.

What does it mean for you?

  1. On these days, people are most likely to read emails. Therefore, the chances of a positive perception of your offer increase.
  2. However, it also means that in the subscriber’s mailbox apart to your newsletter, there will be 50-100 other emails. So, there is a high risk that your message will go unnoticed.

Thus, there are two options: either you send campaigns along with everyone, risking to get lost in the mailbox, or go against the rules and send on less popular days.

If you choose the second way (to go against the “email crowd”), these are results of a survey. The colorful one is the “calm days”, most appropriate for email sending:

If you prefer to follow a proven path, here is a table that will help you to navigate choosing the best mass mailing day in accordance with your primary goal:

Opens Tuesday, Wednesday, Friday
on these days people have cleared the inbox and have a lighter load
Clicks Thursday and Friday
there is more time to read your emails so people also have more time to take action when they feel compelled by your offer
Responses Weekends in the mid-morning
because there’s significantly less email being sent on weekends.
The worst day is considered to be Monday because of the large inflow of messages in the mailbox after the weekend + stress of the first working day of the week.


However, there are always exceptions to the rule.

For example, Dan Zarella’s research “The Science of Marketing” shows that the perfect days to get high Click & Open Rates are weekends.

Let’s summarize the results

  • Want your email to be opened — send during daytime, mid-week.
  • Want to get an answer — send in the evening on weekends.
  • Want clicks — send in the evening at the end of the work week — Thursday, Friday.

Follow/go against the general tactics or find the time that will work best exactly for your business.

If you don’t want to rely on the stats — read these cases of how e-commerce brands found their perfect sending time:
