A click-through occurs when a recipient clicks on a URL link from inside an email newsletter. Click-through tracking refers to the data collected about each click-through link, such as how many people clicked it and how many clicks resulted in a conversion or subscription. The percentage of recipients that click on a given URL relative to how many recipients merely opened the email is known as the click-through rate (CTR). MyNewsletterBuilder (MNB) provides full click-through statistics for each email newsletter campaign you send. A higher CTR is associated with a higher return on investment (ROI) and overall user engagement.
