As we have known for many years, to benefit from your email list, your emails must be opened. There are many articles about the importance of the click-through rate.

However, the click-through rate is entirely dependent on the open rate of emails.

What is Click-Through Rate?

We should increase email open rates because it is obvious that unless people open your email, there’s no chance for them to click through to your store/website!

There are some key points we need to mention in this case. Before we start let’s describe email open rates.

What is an E-mail Open Rate and How to Calculate It?

A lot of people consider email open rates as the number of people who open the email. However, this is not an accurate description of email open rates. We are talking about a very important metric that we need to understand properly.

An email is counted as opened if one of these two conditions occur;

The first condition is,

– The reader allows images in the email to be displayed in the full view of the email or preview pane.

and the second condition is,

– The reader clicks a link in the email.

Open rates are calculated by email service providers. ESPs consider the number of people who open the email and divide it by the number of emails sent that failed to reach the reader.

For example, if you sent out 100 emails, 20 bounced, and 10 were opened, you would have an open rate of 12.5%.

What is an Average Email Open Rate?

Before we start, you should know that the average email open rate differs from country to country and industry to industry. According to MailChimp’s current data,

  • The most opened emails are related to hobbies, with an open rate of 27.35%.
  • Emails sent by government entities come in second, with a 26.52% open rate.
  • With a 26.03% open rate, emails about the arts and artists came in third.

However, they found out that the average email open rate of all industries is 20.81%.

Also, they detected the top 3 industries by click rate. According to their survey,

  • Hobbies have a 4.78% industry standard email open rates.
  • Media and Publishing have a 4.55% industry standard email open rates.
  • The government has a 3.65% industry standard email open rates.

After getting a theoretical background in email open rates. It’s time to increase email open rate stats!

How to Increase Email Open Rates

1. Create an Organic Email List

The quality of an email list is more valuable than the quantity. This is why companies that try to buy large quantities of leads to jump-start their marketing programs will find their open rates very low.  Offering a free trial, running a contest in exchange for an email address, or offering an easy way of subscribing are far better ways to build your list organically.

Popups like the above are very useful tools in creating an organic email list. You may purchase them for your website from a popup provider like Popupsmart to offer your visitors an easy way to subscribing to your email list.

2. Keep Your List Fresh

Don’t forget to update your email list and remove inactive subscribers. You may want to send an email to people who have not engaged in the past 6 months or more. You can simply evaluate the chance of re-engagement. After that, eliminate them from your list. According to Oracle, “invalid rates are the fastest way to trigger filtering and blocking on your new IP.”

Also, if you want to keep your list fresh, try to check up on your subscribers. You can do that by asking whether they would like to update their preferences and information. It would be great to make them feel comfortable about their preferences and the way they engage with your business.

3. Segment Your List

Why You Need to Segment Your Email List?
Opens 14.31% higher than non-segmented campaigns
Unique Opens 10.64% higher than non-segmented campaigns
Clicks 100.95% higher than non-segmented campaigns
Bounces 4.65% lower than non-segmented campaigns
Abuse Reports 3.90% lower than non-segmented campaigns
Unsubscribers 9.37% lower than non-segmented campaigns

People tend to open emails with regards to their relevancy. Think about yourself, when you decide whether or not to open an email, don't you choose the relevant ones? By segmenting your email, you will be able to provide this to your customers.

You can start the segmentation process by adding tags to your subscribers based on their behaviors and preferences. Arranging different emails based on different groups is useful. Furthermore, managing your ongoing emails based on demographics such as age or location is always a good idea.

If you know your consumers, it becomes easy to decide everything else such as subject lines and messages.

MailChimp scanned our system for users who use their list segmentation tools and sampled about 2,000 MailChimp users who sent about 11,000 segmented campaigns to almost 9 million recipients. They compared the results of those segmented campaigns to the results of the same customers’ non-segmented campaigns.
