It shows how your email marketing content performed after opening. The click-to-open rate will be higher if you deliver content that matches your leads&#8217; interests. There will be room for improvement if you don\u2019t get the expected result.<\/p>\n\n\n\n<p>Marketers in the 1990s granted two metrics, open rate and click-through rate, to measure performances primarily. But as a marketer of 21st century, you must know it&#8217;s not enough. High engagement comes not only by opening the email but also by clicking on the given CTA (Call to Action). Focusing on the click-to-open rate would be an excellent way to get an idea of where to improve your customers&#8217; engagement with your business.<\/p>\n\n\n\n<h2>What Is CTOR In Email Marketing?<\/h2>\n\n\n\n<p>CTOR (Click to open rate) is a difference-making calculator that tells you how many people clicked on a link and how many didn\u2019t. A high click-to-open rate indicates that the marketer (like you) convinced the leads with email content to follow a specific action. This way, the click-to-open rate measures how much the content intent meets its goal.<\/p>\n\n\n\n<p>You create your email content based on a particular topic, and all the elements of your presentation, including texts, designs, CTA, etc., must align with that topic.<\/p>\n\n\n\n<p>This metric shows where the alignment is lacking in your content, giving you a huge opportunity to improve your email marketing strategies.<\/p>\n\n\n\n<p>On the other hand, a good email marketing strategy can help you save extra advertisement costs by <a href=\"https:\/\/mailbluster.com\/blog\/lead-generation-how-to-get-leads\" target=\"_blank\" rel=\"noreferrer noopener\">generating more leads<\/a> and nurturing them to turn them into customers.<\/p>\n\n\n\n<h2>CTR vs. CTOR In Email Marketing<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"1200\" height=\"628\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2022\/08\/CTOR-CTR.png\" alt=\"CTR vs. CTOR in Email Marketing\" class=\"wp-image-2570\"\/><\/figure>\n\n\n\n<p>CTR (click-through rate) and CTOR (click to open rate) are similar in measuring the number of interactions or clicks an email gets.

If one of your leads opens your sent email more than once, it will not be counted more than once when measuring unique opens. The same goes for unique clicks.<\/p>\n\n\n\n<p>To calculate the click to open rate, you must first divide the number of unique clicks by the number of unique opens.<\/p>\n\n\n\n<p>Then you need to multiply the result by 100. The formula given below can clarify how to calculate CTOR in email marketing.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"1939\" height=\"972\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2022\/08\/Frame-3453.png\" alt=\"CTOR (Click to open rate) Measurement Formula\" class=\"wp-image-2532\"\/><\/figure>\n\n\n\n<p>If you have 500 Unique Opens and 50 Unique Clicks, the click to open rate would be 10%.<\/p>\n\n\n\n<h2>How to Improve Your Click-to-Open Rate?<\/h2>\n\n\n\n<p>The click-to-open rate helps measure your email marketing performance, as mentioned earlier. You need to remember that you are a human, not a robot, and you send emails to other human beings. So, it must require a connection between you and your customers. If they find your emails irrelevant, they will mark them as spam to keep their inboxes clean. On the other hand, your customers will welcome it only if you take them on a journey through a series of emails.&nbsp;<\/p>\n\n\n\n<p>Basically, the email subject line and the email body affect this metric&#8217;s result. In other words, the CTOR shows where to improve the engagement in your email content. So, improving the quality of the subject line and the body is the best way to enhance your click-to-open rate.<\/p>\n\n\n\n<h3>Email Subject Line<\/h3>\n\n\n\n<p>First Impression always plays a decisive role in any type of communication. In other words, it makes us reach an instant conclusion when we draw our attention to someone. The impact of the first impression lasts long, affecting future communications.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"2087\" height=\"1007\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2022\/08\/Frame-3447.png\" alt=\"First Impression in Communication \" class=\"wp-image-2533\"\/><\/figure>\n\n\n\n<p>The subject line is the element that contains the first impression of your marketing email. If you plan to make a journey to nurture your leads with a series of marketing emails, engaging the subject line and aligning with the whole topic is the most important part. There are things to focus on when writing a subject line.<\/p>\n\n\n\n<h5 style=\"margin-bottom:10px;\"><span style=\"margin-right:10px;\" class=\"badge-round\">1<\/span><strong>Click-worthy subject line<\/strong><\/h5>\n\n\n\n<p>People judge an email with its subject line and mostly report suspicious emails as spam at first glance. Your receivers have the reason to do that, as <a href=\"https:\/\/99firms.com\/blog\/spam-statistics\/#gref\" target=\"_blank\" rel=\"noreferrer noopener\">9<\/a><a href=\"https:\/\/99firms.com\/blog\/spam-statistics\/#gref\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">4<\/a><a href=\"https:\/\/99firms.com\/blog\/spam-statistics\/#gref\" target=\"_blank\" rel=\"noreferrer noopener\">%<\/a> of all malware comes from emails. On the other hand, <a href=\"https:\/\/www.business2community.com\/infographics\/understanding-importance-e-mail-subject-lines-infographic-01492127\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">69%<\/a> of the people report emails as spam based on the subject line.<\/p>\n\n\n\n<p>Subject lines usually contain curiosity making the receivers\u2019 minds open the mail. Although, the automated emails which come from <a href=\"https:\/\/mailbluster.com\/blog\/email-spammer-bot\" target=\"_blank\" rel=\"noreferrer noopener\">spambots<\/a> have the same technique. But, there are differences between human-to-human and machine-to-human communication. Try to write your email subject line that matches your subscribers\u2019 interests.<\/p>\n\n\n\n<p>Here is an example. <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"735\" height=\"180\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2022\/08\/ezgif.com-gif-maker-2.png\" alt=\"Best subject line for good email performances\" class=\"wp-image-2539\"\/><\/figure>\n\n\n\n<h5 style=\"margin-bottom:10px;\"><span style=\"margin-right:10px;\" class=\"badge-round\">2<\/span><strong>Keep it Concise<\/strong><\/h5>\n\n\n\n<p><em>According to <\/em><a href=\"https:\/\/www.business2community.com\/infographics\/understanding-importance-e-mail-subject-lines-infographic-01492127\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><em>Business2Community<\/em><\/a><em>, 47% of the email users open emails based on the subject line alone, and those containing 15 words or below have the most open rate.<\/em><\/p>\n\n\n\n<p>That is, a short and engaged subject line can communicate at its best. The longer your subject line is, the lesser the open rate will be. So, it would be best to reflect the message in your subject line, keeping it as short as possible. What about this? <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"900\" height=\"162\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2022\/08\/ezgif.com-gif-maker-3.png\" alt=\"Keep your subject line shorter\" class=\"wp-image-2540\"\/><\/figure>\n\n\n\n<h5 style=\"margin-bottom:10px;\"><span style=\"margin-right:10px;\" class=\"badge-round\">3<\/span><strong>Personalize<\/strong><\/h5>\n\n\n\n<p><a href=\"https:\/\/www.business2community.com\/infographics\/understanding-importance-e-mail-subject-lines-infographic-01492127\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"><em>Business2Communication<\/em><\/a><em> also claimed that personalized subject lines have 22.2% more opens than those not personalized.<\/em><\/p>\n\n\n\n<p>So, why wouldn\u2019t you try it!

Emojis are a great hack as it allows them to understand each other online through emojis.

After knowing the targeted topic, write a subject line that primarily reflects the message. If you don\u2019t align the subject line with the body, CTA and the whole case, your receivers might misunderstand the whole concept and report your email as spam.<\/p>\n\n\n\n<p>An email from <a href=\"https:\/\/www.birchbox.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">BIRCHBOX<\/a> can be an example of good alignment.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"386\" height=\"923\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2022\/08\/ezgif.com-gif-maker-6.png\" alt=\"Align your subject line with the whole topic for best CTOR\" class=\"wp-image-2543\"\/><\/figure><\/div>\n\n\n\n<h3>Email Body<\/h3>\n\n\n\n<p>People rarely read email content from top to bottom thoroughly. So, writing email content in detail, like blog posts, might lower your click rates, affecting the CTOR. Email body has the responsibility to enhance your click rates. There are good practices to improve this part.<\/p>\n\n\n\n<h5 style=\"margin-bottom:10px;\"><span style=\"margin-right:10px;\" class=\"badge-round\">1<\/span><strong>Focus on Customers\u2019 Interests<\/strong><\/h5>\n\n\n\n<p>Can you forget about yourself when focusing on your customers? It would be great if you watched from their perspective to understand what they feel about their needs.

You can segment your customers using <a href=\"https:\/\/mailbluster.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">MailBluster<\/a> based on their interests.

The genuine concern is that it hampers most email users&#8217; privacy.&nbsp;<\/p>\n\n\n\n<p><a href=\"https:\/\/support.apple.com\/guide\/iphone\/use-hide-my-email-iphf277f837e\/15.0\/ios\/15.0\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Apple<\/a> announced a new&nbsp;<a href=\"https:\/\/mailbluster.com\/blog\/apple-mail-privacy-protection\">mail privacy protection (MPP)<\/a> for IOS 15.2 or later in <a href=\"https:\/\/www.apple.com\/newsroom\/2021\/06\/apple-advances-its-privacy-leadership-with-ios-15-ipados-15-macos-monterey-and-watchos-8\/\">June 2021<\/a>. New MPP will prevent the Invisible Pixel or Spy Pixel from tracking users\u2019 data. Whenever the receiver gets an email, the device will automatically preload the mail, including the Invisible Pixel. As a result, the spy pixel won\u2019t be able to track the email open rate because all the emails will be tracked as opened.
