Most importantly, how to improve your open rates? In this blog, we’ll cover the open rate metric in-depth and share some proven strategies to improve your open rates. So, hang tight and read on because it will help you improve your marketing efforts. 

Let’s begin. 

What is Email Open Rate?

Your email open rate signifies how many subscribers open your email. Basically, it’s the percentage of recipients who opened your email from your entire subscriber list. 

Let’s say you sent an email to 100 people. 46 people opened your email, so your open rate is 46%. 

Open rates tell how many people are interested in your newsletters and is the first step towards building a successful email marketing strategy. Because no matter what you add to your email marketing campaign, if they don’t open it, they won’twitness what’s next from your side. 

How Email Open Rates are Calculated? 

Your open rates are based on the number of emails that landed in the inbox and unique opens. To calculate the open rate, you need the following figures: 

• The number of emails sent; 
• Bounced emails or emails not delivered; 
• Unique opens; 

Once you have these numbers, just use the following formula: 

Email Open Rate = Unique Opens / (Emails Sent – Emails Bounced) x 100

For example, If you send 120 emails, 20 didn’t get delivered, and 30 people opened your emails, then your open rate will be: 

Open Rate = 30/(120-20)*100 = 30%

Factors Affecting Open Rates

Have you ever noticed that some of your emails are opened by the majority of your audience while others fail to be noticed? Your open rates depend on many factors you might be overlooking in your email marketing journey. 

Here are the most important factors affecting your open rates: 

• Subject line. Your subject line is the most important criterion, as it is the first thing your subscribers notice. Make sure to have a compelling and relevant subject line. Keep it short and interesting; 
• Preheader. It’s the text right after (or below) your subject line. Tease the readers with something that would make them click; 
• Name & email address. Use a name and email your subscribers recognize. If it’s your company list, use your name and official email ID while sending an email campaign; 
• Segmentation. In 2024, relevance matters the most. So, always segment (group) your email list and send personalized emails to every segment suiting their interests, preferences, or location; 
• Timing. Sending emails at the right time is crucial. Look at your past campaigns to find when your audience is most active. According to research, Tuesdays and Wednesdays are the best time to send a marketing email; 
• Frequency. Spamming your subscribers with lots of emails will adversely affect email campaign performance. Always test the right email frequency based on your goals and subscriber engagement.

What is Click-to-Open Rate? 

Click-to-open rate (CTOR) is different from click-through rates in paid campaigns. CTOR tells how effective your communication was by calculating how many people opened and clicked a link within the email. Basically, you track this metric to see your subject line effectiveness, compelling nature of your email content and design, and finally the CTA. 

Your CTOR also depends on how relevant and personalized your email campaign was. Emails with personalized email subject lines, content, and offers tend to have a higher CTOR rate (12.70%) than ones with generic subject lines.

Common Pitfalls and How to Avoid Them

Sometimes, despite your best efforts, your emails can register low open rates. If you’re also stuck with such a scenario, here are some common mistakes and tips on tackling these issues. 

Overloading Recipients With Emails

When it comes to emails, less is more. Meaning, you should always focus on quality rather than quantity. So, rather than blasting subscribers with emails, maintain a consistent frequency and stick to it. 

Look at your analytics to find the best times to send emails and how engaged your audience is. Based on the reports, decide how often (and how much) you should email your subscribers. 

It’s a good practice to send your emails on a specific day of the week and let your subscribers know about it in the welcome email itself, if you’re targeting better open rates. 

Here are some more tips to avoid spamming and information overload: 

• Ask your audience about their preferences by conducting regular surveys and taking feedback; 
• Personalize your email frequency based on audience preferences and engagement data; 
• Communicate expected frequency in your welcome email or sign-up page; 
• Schedule your emails at regular intervals using marketing automation; 
• Never send an offer or newsletter more than twice a week. 

Ignoring Email Deliverability Issues

Your email performance also depends on how compliant you are with compliance and deliverability norms. This includes taking care of the following factors: 

• IP address reputation; 
• Domain reputation; 
• Unsubscribe rate; 
• Spam rate; 
• Email bounce rate; 
• Sending frequency; 
• DKIM, DMARC & SPF records. 

Many businesses ignore these technical aspects (or have no idea about it) when setting up an email campaign. It’s important to look into these email marketing metrics and set up your accounts/domain properly before shooting out emails to get the best results. Here’s a checklist for you:

Ignoring List Hygiene

List hygiene is an important factor for open rate optimization. If you’ve got an email list filled with outdated subscribers and undeliverable addresses, you can’t expect to beat average click through rate and open rates. 

You may also be marked as spam by an email service provider in case your emails bounce often, which will impact your sender reputation. 

So, regularly clean and maintain your email list. Here’s how you can achieve great list hygiene: 

• Use double opt-in process for new subscribers to ensure they’re interested and have a functional email; 
• Conduct regular audits of your email list and remove disengaged subscribers; 
• Segment inactive subscribers and run a re-engagement campaign. In case they’re not responsive, clean up your email list; 
• Respect unsubscribe requests and maintain compliance with GDPR, CAN-SPAM and other data privacy laws.
