Introduction:

A Click-To-Open Rate (CTOR) Calculator is a tool used in email marketing to assess the effectiveness of a campaign. It calculates the percentage of recipients that opened the email and then clicked on a link or call-to-action (CTA) within it.

The CTOR provides a more concentrated perspective of engagement than the Click-Through Rate (CTR) which calculates clicks based on the total number of emails sent. CTOR helps marketers evaluate how appealing the email's content was to the subscribers who opened it.

How to Calculate Click-To-Open Rate?

To calculate the Click-To-Open Rate (CTOR) for an email campaign, you can follow these steps:

  • Determine the number of unique clicks:
    Count the number of individuals who clicked on a link or call-to-action (CTA) in the email. This is usually offered by an email marketing platform or an analytics tool.


  • Determine the number of unique opens:
    Count the number of individuals who opened the email. Again, this information is typically available through your email marketing platform or analytics tool.


  • Calculate CTOR:
    Use the formula to calculate the Click-To-Open Rate:

    CTOR = (Users Who Clicked x 100) ÷ Email Opens

    Substitute the values from steps 1 and 2 into the formula to get the CTOR percentage.

    Example:
    Suppose there are:
    Unique Clicks: 500 recipients
    Unique Opens: 1000 recipient

    Then,
    CTOR = 500​/ 1000 × 100% = 50%

    So, in this example, the email campaign has a 50% Click-To-Open Rate. This signifies that 50% of the recipients who opened the email also clicked on a link or call to action inside it.
