Unlimited Email Tracker by Snov.io

Very useful , time saving and helpful tool

Works fine; it does what it’s supposed to do. I’m getting this kind of feature for free—wow!

Love it! Also free version is very helpful

Well, Before installing i was not sure what is written in description will be true. But I'm now fully satisfied how good it works and relieve my stress of how i used to think that someone open my email or not. I'm now get direct notification when someone open my sent email. So higly recommend to install if you want to get these benefits for free. Thank YOu.
