This is a GREAT product at a great price. I am not currently using the email functionality yet (I consider that a bonus tool in my case). What I absolutely LOVE is the second extension you get - which allows you to easily and quickly add a website to a google sheet as you are browsing. For example, I have google sheets for competitors, suppliers, resources, etc. As I am browsing I can just click the extension and it will add that site (along with metadata/description) to one of these sheets. I can't tell you how useful and time saving this has been. Do not miss this product. It's fantastic.
