Sending an email notification when a page is visited / a goal is reached?

Question

JavaScript

There is a problem: a subscriber in a letter clicks on a link marked with utm tags, gets to the page, it is necessary that a notification / letter is automatically sent to my email when visiting the page (like, here is a new visit to the page, and even better, the utm tag is transmitted to the letter - subscriber's email). As a result: so that when a subscriber visits a certain page, a letter arrives in the mail (a new visit to the page by a subscriber with such and such an email).
How can it be implemented? It seems like a simple task, it’s a pity there is no email notification in the metric about the achievement of the goal ...
