CTOR stands for Click-to-open rate, a marketing & advertising abbreviation.
Email metric equal to unique clicks divided by unique opens, showing how persuasive the content was among people who opened the message.
Example: Our CTOR is strong, so the problem is the subject line, not the email body.
Usage notes
Apple's Mail Privacy Protection, introduced in 2021, inflates open counts by preloading emails, which makes open-based metrics such as CTOR less reliable.
