Hi Shamin,
Sorry .. but … you wrote me this email feature to copy your email address was already present in the plugin and that you were suppressed at the suggestion of your buyers.
This is indeed curious, it was enough just to put a confirmation button if you want an email with your address or not, to satisfy those who did not want him and those who, like us, have an absolute need.
Then the code you already wrote it, it is only copy or activate.
Certainly, just as it is done your plugin is not complete!
You can do something or I have to see what else I find on the web?
Keep in mind that we are owners of more than 350 domains, and that we may need this or your other plugins for many other applications.
Greetings.
Alfio
