When viewing email statistics under the 'Statistics' Tab, you will see both Opens and Unique opens.  

(This also applies to 'Clicks" and "Unique Clicks")



• "Opens" is the number of times your email campaign has been recorded opened. An email can be opened multiple times, and it will be recorded multiple times.


  
• "Unique Opens" is the number of unique recipients who opened the email.
  

For Example:


Contact A open his email 3 times,
 Contact B open her email 2 times,
 Contact C open her email 5 times.

 

Opens = 10


Unique Opens = 3
