Is there any method to your email-sending madness?

Or do you just send them whenever you get around to it? (Or when you’re burning the midnight oil?)

You can actually schedule emails in Gmail to send at certain times.

So technically, there’s really no excuse not to be scheduling your emails.

But the trick is figuring out exactly when you should be sending them. Identifying the best times and days to make sure your message is heard loud and clear.

When you schedule your emails to go out at the best time and day for your customers, you’ll get more opens, clicks, and responses – because people will actually have the time to pay attention to what you have to say.

Here are the best times and days to schedule emails (and how to do it).

The 4 Best Times to Send

The goal isn’t to get your email opened.

It’s to get your email acted upon. You need clicks, interactions, and replies.

The problem is that different studies have shown differing results across the board. Here are a few of the generally accepted ‘best times’ to send emails:

  1. 10 AM – Late morning send-times are often most popular, but out of every time during the late morning, 10 AM was found to be the most successful.
  2. 8 PM – midnight: Seems crazy, right? But emails usually get more clicks or opens later on in the day, as it’s winding down. This is probably because we like to check our phones/email before turning in for the night.
  3. 2 PM – Late afternoon is a great time to send out an email, as people might be preparing to wind down their work day (or procrastinating).  
  4. 6 AM – Some people start their day by checking their phone while still in bed. It’s often the first thing that some people think about, so this time makes sense. And if emails are rolling into your inbox as you’re waking up, you’re more likely to check those notifications during a routine morning “phone check.”

Note: remember your customer’s time zones. You might need to shift these around depending on the time zone that the majority of your customers are in.

Customer.io has found that while people do check their email in the AM, they might be likely to avoid marketing emails and prioritize ones that contribute to their daily productivity instead.

HubSpot focused their research on open times and found that late morning emails got the highest total number of opens. Their research uncovered that 11 AM was a peak time for email opens.

MailChimp research, analyzed by Wordstream, uncovered that 2 PM is a common time for sending email, as opens were highest in the afternoon to late evening.

That’s a start. You now know when to test email-sending each day.

But which day should you send them?

Let’s find out.

The 3 Best Days to Send

Once again, differences apply.

Your customer’s lifestyle, for instance. Young Millennials and middle-aged desk jockeys have vastly different schedules.

But here are the CliffsNotes for which days perform best:

  1. Tuesday: Most of these studies found Tuesday is the best day to send emails. Use Tuesday as a starting point over other days in this list.
  2. Thursday: If you’re planning to send out two emails in a week, it might be a good idea to choose Thursday as the second day to engage customers.
  3. Wednesday: This day came in second place in some studies, so it’s a good day to keep in mind as well.

HubSpot found that Tuesday was the best day for sending out emails, with Monday and Wednesday following very close behind:

GetResponse research uncovered that inbox activity was at its highest on Thursday, with Wednesday coming in second place.

MailerMailer uncovered that Tuesday was the best day for opens, and Wednesday was the second best day.

Sundays took the cake for clicks, with Tuesday getting the next closest amount. However, a higher click-through rate on Sundays might be attributed to the fact that Sunday had a lower amount of total opens.

Why Your Best Time and Day Might Differ

You know what the research has suggested about the best times and days to send.

But there are tons of variables that might make those numbers different for you. Here are two things to consider when trying to uncover the optimal times and days to send emails out to your audience:

  1. Start with the best times and days listed in the research above.
  2. Run tests for these days and times to see which ones work best for you.

Basically, you want to test the results of major studies within your own email list.

For example, you can do it formally with segments of emails. Or informally by alternating when you schedule each email.

Your findings might uncover that Wednesday is the top day to send emails, while 11 AM is the perfect time. Your customers are different, so you want to find out what the open and click habits of your target audience actually are.

Fortunately, you can use Contact Monkey’s Email Tracking to find what works best.

You can see exactly who has been opening your messages, or automatically throwing them in their “trash” folder. Turn on desktop notifications for every clicked link and read email.

You can see a whole lot more than just when your emails are getting opens. You can find out which device they are being opened on – so your follow-ups can be optimized for those devices.

Example: Are the majority of opens happening on mobile? Make sure your initial and re-engagement emails are extra mobile-friendly.

You can also see the location of each user who opened emails or clicked on links, which you can use to your advantage during re-engagement, also.

Contact Monkey will configure statistics on your dashboard to show you what your top links, subject lines, cities, and more have been.

Click on the graph to get an overall sense of what is performing well (or not so well) with these simple statistics.

You can actually use tools to schedule emails in Gmail to send at the best times and days from your findings. You don’t have to do it manually.

How to Schedule Gmail Sending with Delay Send

Once you know the best days and times for your business, you can easily select them and manage your email campaign schedules with Contact Monkey’s Delay Send for Gmail.

Here’s how it works.

Scheduled Send

Use Gmail Delay Send to plan out emails to send at a later date or time, all with just a few simple clicks. Timed email is as simple as selecting your date, time, and recipient(s), and clicking “Send.”

Draft it Out

Maybe you just came up with a great idea for a personalized email, and you need a place to outline your thoughts while it’s still on your mind.

Or you want to send it out, but it’s an odd time of day (like 2 AM, because you’ve been working really hard to optimize your email list. Kudos to you!)

Start by drafting what you want to say right when you think of it, and then schedule it for later. You can come back to it and update it in the meantime, or simply send it out at a more appropriate hour.

Did it Send?

If a scheduled email isn’t actually sent out for some reason, you’ll receive a notification to let you know that it wasn’t sent out – along with an explanation of why.

But if it was scheduled successfully, you’ll get a confirmation as well.

That way, there’s no guesswork about the fate of your email campaign.

And once it’s scheduled successfully, you’ll see it show up in your Outbox so you can manage all of your scheduled emails easier.

Get Edit Happy

Maybe you’ve got a post scheduled, but you want to switch the date and time.

Or you thought of some more brilliant content to include.

You can cancel scheduled emails, or edit them, right from your inbox with no sweat.

How to Schedule Gmail Sending with Boomerang

Boomerang for Gmail is similar to Contact Monkey’s Delay Send. It allows you to be in control of when your messages are sent.

But, with Boomerang, you can also control when you receive them.

Here are a few examples.

Send it Later

With Boomerang, you can write out an email to automatically send out later at the time of your choice.

Once Boomerang has been installed, just write out your email, and then click “Send Later.” Like ContactMonkey, you will then be able to select from several different dates or times to send out the message, such as “in 1 hour” or “in 2 weeks.”

You can also create a specific, customized time and date.

Get Reminders

Ever send out an email, and know you need to follow up if you don’t hear anything back or get the results you’re looking for?

You can select reminders in Boomerang to prompt you to follow up if someone doesn’t reply, or if you want to send a second email within a specific time frame following the first.
That way, you aren’t dropping the ball on follow-ups and re-engagements.

Inbox Clean-Up

Ever want to tidy up your main inbox, but you avoid doing so because you don’t want to lose your really important messages?

Boomerang can actually remove messages from your inbox until they’re needed.

Click the Boomerang icon when an email is open, and then select when you want to see it in your inbox again. Then, Boomerang will archive your message and send it back into your inbox as an unread or starred email.

You can even make the message re-appear at the very top of your inbox, hence the name “Boomerang.” Pretty clever, right?

Get Responses With Respondable

Here, you can add in an automated AI assistant to help you write emails that will actually get responses.

Respondable helps you make every email more likely to get a response by helping you to set a fitting tone.

Data based on millions of analyzed messages helps you use wording that helps you achieve the overall goal of an email.

The Respondable bar (on the right-hand side) shows you how likely you are to get a response by placing scores on different areas of your writing:

You’ll then receive an overall grading at the top of the bar, ranking your message from “very unlikely” to “very likely” to receive a response.

You can click on each score to find an explanation for your grade:

Boomerang isn’t just another awesome tool for scheduling email. It can also help you:

  1. Turn off email during specific times that you choose
  2. Turn auto-response on
  3. Select inbox expectations if you only want emails from specific contacts coming through at certain times
  4. Hide emails. This feature works like Unroll Me. Emails are coming in, but they’re being placed under an alternate label (instead of your inbox) until a certain time. It helps keep distractions at bay.


According to research, the best times to schedule Gmail sending are 10 AM, between 8 PM and midnight, 2 PM, and 6 PM.

The best days, based on research, are Tuesday, Thursday, and Wednesday.

But of course, your best times and days will probably differ based on your audience, industry, and a ton of other factors.

So you need to put a bit of extra legwork into identifying which times and days get the most responses from your audience.

You can easily do this with Contact Monkey’s Email Tracking feature. Just track opens, clicks, and responses from campaigns sent at these “best times,” and see how your emails perform.

Remember to adjust for different time zones and focus on the time zone that the majority of your customers are located in.

For instance, if your customers are primarily located on the east coast, but you are located on the west coast, you’ll have to keep the 3-hour time difference in mind.

Once you’ve identified your best times and days to send, put that data to good use and adjust your campaigns accordingly.

Use Contact Monkey’s Delay Send or Boomerang for Gmail to schedule Gmail send. Send Gmail later, receive reminders, and edit your work before you hit send.  

If your performance numbers start dropping after a few months, remember to re-test your best times and days to see if they have changed as your audience has evolved.

Your message might not be bad. It just might have been received at the wrong time.
