Why Does Email Open Rate Matter?

Your email open rate matters because it directly affects the success of your email marketing campaign.

To put it another way, it’s the percentage of emails delivered to your list and how many people have opened those emails that counts.

However, it is important to note that there is a difference between open rates and click-through rates (CTR).

Your email click-through rate (CTR) measures the percentage of recipients who clicked on the links in your email against the total number of subscribers who received the email.

Now let's find out what is the email open rate.

What is an Email 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.

In order to count an email as opened, it must meet one of these two conditions;

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

2. 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%.

➤ 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.

How to Increase Email Open Rates?

1. Create an Organic Email List

Quality or Quantity? This is the question.

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.

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, and then 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 every once in while and see if they engage or not.

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

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. The following table can give you more reasons why you need to segment your email list.

Email Segmentation Statistics
 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.
 Unsubscribes  9.37% lower than non-segmented campaigns.

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 their 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.

Try to increase email open rates organically by email segmentation and don’t forget the golden rule: ”RELEVANCY!”

4. Avoid Spam Filters

The common problem of email marketing is that your emails can be sent to your visitors’ spam folder.

In this case, you should have:

  • A good IP address.
  • A good email service.
  • A clean template code.
  • A verified domain.

Include a clear unsubscribe link in your email footer and try to optimize it as much as possibe.

Use branding in your “from” name:

Send emails to people who have actually opted-in to receiving your emails. After that, use merge tags to personalize your emails. After gaining your consumers' trust you may ask them to add you to their address book.

Don’t use spam trigger words so as not to be blocked by spam filters. Finally, don’t forget to include your location in your emails. These tips will be useful to increase email open rates.

You should build a sub-domain for email marketing efforts. It’s not an obligation for everyone. However, it might be useful for the domain-specific monitoring of your IP reputation.

14. Check Your Sender Reputation

If you have low sender score then your emails will automatically be rejected by ISPs and won’t be delivered. Wait! What is this Sender Score?

Let me explain it, clearly.

Sender Score is basically an algorithm that ranks every outgoing mail server’s IP address. It shows your sender reputation on a scale of 0 – 100. Some email metrics determine the Sender Score by the unsubscriptions or spam reports. If you want to know your Sender Score, go to Return Path’s registration page.

Using a double opt-in form is always a good idea to avoid spam complaints and improve email open rates. You can send a confirmation email to the new subscriber in order to verify their address and build the agreement.

As a short line of text that added to domains txt record, it is stored in the domain name system in cooperation with A, PTR, and MX records. That means it increases your quality reputation with regard to the receiving email server.

17. Look at Blacklists

DNS-based blacklists are created to protect users from IPs that have received a high volume of spam reports. You shouldn’t be on the list. It won’t be good to increase email open rates.
