Click to Open Rate?

What does the "Click to Open" rate mean when sending an email campaign?

[Anonymous]

It's a ratio of Clicks per Open- so if you had 10 Opens and 1 Click you'd get 10%.

Here's a great definition from marketingland.com:

"CTOR measures the relevancy and context of an email by taking the number of unique clicks divided by the number of unique opens, and then multiplying by 100 to show it as a percentage. What it tells you is simply this: Of the subscribers who opened the email, how many clicked."

The formula is:  (Unique Clicks/Unique Opens)*100
