Email clicked
What is Email clicked? When you send out an email, email clicked is how many times the email was clicked. Some people can click on an email 10 times which might skew your results.
So, it is better to use an independent email link or just link tracking system that actually tells you how many UNIQUE clicks you got.
So, how many unique individuals clicked your email and not just the total click rate. One such tool is call "Click perfect." I have used it before. It is cheap and it is effective and it works and it gets the job done.
