As the standard &#8217;email open&#8217; tracks every open event, COR counts only those opens you can be sure about.<\/strong><\/p>\n<p>Most email platforms track &#8220;opens&#8221; by placing a tiny invisible image (a tracking pixel) inside. This image sends an event to the system saying that the email has been opened. This method sounds simple, but it has a few issues.<\/p>\n<p>First, it depends on the recipient enabling images in their email. If they don&#8217;t, the pixel never loads, so the open isn&#8217;t tracked, even if the person read the email. Conversely, some email clients or devices preload images, triggering a false open even if the email was never read. Plus, these days, privacy settings like Apple&#8217;s Mail Privacy Protection make tracking even trickier by automatically loading these pixels regardless of user behaviour.<\/p>\n<p>The Confirmed Open Rate attempts to get a more accurate signal by adding a second layer of confirmation and\/or ruling out opens that happened too quickly for a human to open the email. Rather than logging an open based on the tracking pixel alone, COR counts only those opens backed up by a secondary action, like a click. So, if someone opens your email and clicks on a link inside, that&#8217;s considered a &#8220;confirmed open.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Confirmed Open Rate (COR) is a metric used in email marketing to measure the number of recipients who opened an email. <\/p>\n","protected":false},"featured_media":0,"template":"","cat_topic":[],"cat_glossary":[],"class_list":["post-169325","concepts","type-concepts","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/spotler.com\/en-de\/wp-json\/wp\/v2\/concepts\/169325","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/spotler.com\/en-de\/wp-json\/wp\/v2\/concepts"}],"about":[{"href":"https:\/\/spotler.com\/en-de\/wp-json\/wp\/v2\/types\/concepts"}],"version-history":[{"count":0,"href":"https:\/\/spotler.com\/en-de\/wp-json\/wp\/v2\/concepts\/169325\/revisions"}],"wp:attachment":[{"href":"https:\/\/spotler.com\/en-de\/wp-json\/wp\/v2\/media?parent=169325"}],"wp:term":[{"taxonomy":"cat_topic","embeddable":true,"href":"https:\/\/spotler.com\/en-de\/wp-json\/wp\/v2\/cat_topic?post=169325"},{"taxonomy":"cat_glossary","embeddable":true,"href":"https:\/\/spotler.com\/en-de\/wp-json\/wp\/v2\/cat_glossary?post=169325"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
