How to notify through email in wordpress when visitor clicks on a link that this link was pressed and/or user ip, city and country was this?
I have given the link a class 'email-link'.

Answer 1

something like this should get you started
// functions.php
// HTML form markup
function mail_form_stuff() {
echo '<form action="' . esc_url( $_SERVER['REQUEST_URI'] ) . '" method="post">';
echo '<p><input type="submit" name="send_the_email_to_admin" value="Click this button"></p>';
echo '</form>';
}
// make sure the email will allow for html -- not just plain text
add_filter( 'wp_mail_content_type', 'send_the_email_to_admin_content_type' );
function send_the_email_to_admin_content_type() {
return 'text/html';
}
// if the button is clicked, send the email
function deliver_mail_link_stuff() {
$admin_email = get_option( 'admin_email' );
if ( isset($_POST["send_the_email_to_admin"]) ) {
$_user = wp_get_current_user();
$_name = esc_html( $_user->user_firstname );
$_email = esc_html( $_user->user_email );
$to = $admin_email;
$subject = "Some person clicked my link";
$message = 'Hey this person clicked on that button'.'<br>';
$message .= "the persons email address was: $_email";
$headers[] = "From: $_name <$_email>" . "\r\n";
// $headers[] = "Bcc: John Smith <jsmith#gmail.com>" . "\r\n";
// If everything worked -- display a success message
if ( wp_mail( $to, $subject, $message, $headers ) ) {
echo '<p>sent</p>';
} else {
echo 'An unexpected error occurred';
}
// reset wp_mail_content_type
remove_filter( 'wp_mail_content_type', 'send_the_email_to_admin_content_type' );
}
}
function add_short_code_stuff() {
ob_start();
deliver_mail_link_stuff();
mail_form_stuff();
return ob_get_clean();
}
add_shortcode( 'EMAIL_BUTTON', 'add_short_code_stuff' );
this will add a short code for you
you can then call the shortcode in your theme with
echo do_shortcode('[EMAIL_BUTTON]');

You can't do this as a direct consequence of WordPress since a link is HTML and has no correlation to or integration with anything controlled or processed directly by WordPress. WordPress is merely a structure/processes through which you can add info to a database and then later retrieve it.
If you question is actually meant in a more generic and not specifically wordPress sense, then the answer is any number of ways. You could for example create some JQuery or JS that would add that info everytime a link was clicked. But, you would need to interact with the page headers to try and get all the required info.
But, why bother doing that when a free & arguably market leading tool that does this is already available?
The logical process to this is to use Google Analytics (or a rival tool) as this already collects this kind of info with very little work required to set it up. If you want more specific "event" triggered data (eg a link is clicked), then you can also do this fairly easily too.

UPDATE
In your comment, you clarify that you want a real time email to be sent to you when a link is clicked, and thus analytics isn't going to fit the bill. In that case you will need to do some work using JQuery & AJAX.
In simple terms you'll need to do something this:
1) Create some JQuery to intercept the url of the link clicked
2) Pass the link (and header info) to a function via an AJAX call
3) Process the header data / send the email
4) Redirect user to the url passed from the link
