Yes, you read that right:

With digital commuting and flexible working hours on the rise, the old 9-5 is no longer what it used to be. In fact, many workers check their email at virtually all hours.

But should you send emails late at night?

If you’re going to go down that road, you should try doing it very early in the morning.

But how many of them are actually opened and read?

Let’s find out.

At this point, you’re probably thinking:

“Hold on a second there, buddy, didn’t you just say it’s best to send emails around 11 am EST on Tuesday?”

I did indeed.

News flash:

While that’s a good rule of thumb – and, indeed, one that many experts swear by – things may vary depending on your target audience.

For example, workaholics compulsively check their work email all the time, including first thing in the morning on Saturday over a cup of coffee in bed.

The same goes for response rates:

Opening an email is one thing – actually replying to it is quite another. So, the optimal time for opens is not necessarily the best time to boost your email response rate and vice versa.

You should bear this in mind when trying to determine what is the best time to send a mass email to your target audience.

But wait!

There’s more:

  • Emails with promotional sales and specials lead to more opens between 5 pm and 10 pm.

Think of the type of email you’re sending and who your target audience is.

Lawyers, on the other hand, are a completely different school of fish. They like a bright and early start to their day.

Except maybe during the holidays.

Let’s face it:

Nobody likes to open, let alone reply to business or marketing emails during the holidays. Instead, people want to spend their time catching up with friends and family or simply relaxing and recharging their batteries.

That’s why they won’t bother opening your precious email, even if the subject line piques their interest. And the longer your message sits in their inbox, the less likely people are to read it.

When it comes to what is the best time to send an email during the holiday season, this is the bottom line:

Send emails during the last couple of business days leading up to major holidays or immediately after.

And on that festive note:


Whether you’re a legendary tennis player with a silky-smooth forehand or an up-and-coming marketer who wants to take over the world, perfect timing is everything.

In this day and age, when users are bombarded by countless emails, it’s vital that you send out an email at the optimal time.

Here’s the key takeaway:

First, get to know your target audience and its email reading habits.

Second, calculate your email open rate and see how it compares to the average in your industry.

Third, don’t be afraid to experiment with different approaches to see what works best for your business.

And now that you know, what is the best time to send an email, you have a solid foundation to build on.

Game, set, and match.
