When I view the results of my mailing, I see different results for 'Clicked' and 'Total Clicked' and also 'Opened' and 'Total Opened'.
Oracle B2C Service, Outreach and Feedback, Mailings
The total number of clicks refers to the total number of times a person or persons click on the link to your survey within the mailing. So, if Person A clicks on the link to your survey four separate times, and Person B clicks on the link to the survey three separate times, then the Total Clicks = 7, and Clicks = 2. Essentially, total clicks = total number of clicks and clicked = the number of unique clicks (or the number of individuals that clicked on your survey link).
The same theory can be used for Total Opened vs. Opened, but this statistic refers to the number of times your email (containing the link to the survey) was opened. So, if Person A opens the email eight times, and Person B opens the email seven times, then Total Opened = 15, and Opened = 2.
Note: In the standard Tracked Link Activity report, these are labeled 'Total Clicks' and 'Unique Clicks' to help distinguish the difference.
