The Best Times to Send Cold Emails to Improve Open Rate

Your email staying unread in someone’s inbox is the equivalent of digital purgatory. You’ve put in the effort, crafted the perfect email, and hit send only to have it disappear into the digital abyss.

So, what gives? Is there a best time to send cold emails?

There are a few things that can contribute to your emails being left unread (forever), but one of the most common reasons is timing. Sending an email at the wrong time can mean the difference between getting read and getting deleted.

The answer, unfortunately, is that it depends. It depends on your industry, your recipient’s location, and a whole host of other factors.

What can affect email open rates?

There are a few things that can affect email open rates:

  • The subject line
  • The sender
  • The time of day
  • The security of the email

The subject line

The email subject line is often the first thing your recipient will see. It’s what will determine whether or not they open your email. So, it’s essential to make sure that your subject lines are clear, concise, and interesting.

For instance, “360° market overview for {Company name}” is a lot more likely to get opened than “Can I pick your brain?” The first subject line offers value to the recipient and is personalized. The second subject line, on the other hand, comes across as needy and self-serving.

You want to avoid sounding sales-y, spammy, or pushy. Instead, focus on creating email subject lines that are direct, benefit-focused, and make it clear what the email is about.

The sender

Another thing that can affect email open rates is the sender.

If your recipient doesn’t know who you are, they’re less likely to open your email. That’s why it’s crucial to include your name and contact information in the email signature.

You should also avoid using generic email addresses like info@ or sales@. Instead, use a real person’s name and email address. This will make it more likely that your recipient will open the email.

The time of day

The time of day can also affect email open rates. If you’re sending an email outside of regular business hours, your recipient is less likely to see it.

That’s why it’s important to consider your recipient’s time zone when you’re sending cold sales emails.

You should also avoid sending emails early in the morning or late at night. These are times when people are less likely to be checking their email.

Unless, of course, you’re explicitly targeting night owls or early risers. Or, the person you’re emailing is notorious for being glued to their inbox.

Instead, aim to send your email during normal business hours. This is when people are more likely to be checking their email and, as a result, more likely to see your message.

The security of the email

Another thing that can affect email open rates is the security of the email.

If your recipient sees that your email is from an unknown sender or that it’s not been adequately secured, they’re less likely to open it. This is why it’s essential to ensure that you’re using a secure email service and that your recipient knows who you are.

The best days to send cold emails

Now that we’ve gone over some of the things that can affect email open rates, let’s talk about the best days to send cold emails.

There’s no magic day to send an email. It’s going to vary depending on your recipient and their schedule. However, there are some general times and days that are more likely to work than others.

The days

According to various studies, Tuesday and Thursday are the best days to send cold emails, closely followed by Wednesday.

Sundays are for family, and Saturdays are for fun, which means that Tuesday and Thursday are the best days for getting things done.

Mondays are tough because people are trying to catch up from the weekend and get back into the swing of things.

Friday is when people are getting ready for the weekend and may not be as focused on work.

Of course, this isn’t set in stone. If you know that your recipient is more likely to check their email on a different day, by all means, send it then. But, generally, Tuesdays and Thursdays are the best days for sending a cold email.

The best times to send cold emails

Taking a calculated approach to when you send your cold email can make a big difference in your open and response rates. It’s not just about choosing the best day of the week, though. You also need to select the best time of the day to send your email.

According to studies, the best times to send cold emails are between 8.00 to 11.00 am in the recipient’s time zone.

This is because officials usually start their work day early and have more time to check their email before things get too hectic. The same goes for students who are usually up early for classes.

In addition, smartphones have made it easier for people to check their email anytime. So, even if your recipient is out of the office, they’re still likely to see your message first thing in the morning.

You can also try sending out your cold email at 5.00 am as it ensures your email will be at the top of your recipient’s inbox.

When to avoid sending cold emails

You want to stay away from the end of the day. This is when people are winding down and may not have the time or energy to respond to a cold email. Plus, they’re more likely to see your message as an interruption and throw their phone across the room in frustration. (Or, you know, just delete it.)

You also want to avoid lunchtime. This is when people are, well, eating lunch. They’re not thinking about work, and they’re not going to be in the mood to respond to a cold email.

While we’re at it, we should mention that holidays are also a bad time to send cold emails. People are likely to delete your email if they’re sipping piña coladas on a beach instead of sitting at their desks.
