Glad that you managed to resolve it, with regards to wp_mail it should be semi-straight forward

// Updates FYI last update timestamp when custom field is updated
function my_acf_save_post( $post_id ) {
  // bail out early if we don't need to update the date
  if( is_admin() || $post_id == 'new' ) {
     return;
   }
   global $wpdb;
   $datetime = date("F j, Y g:i a");
   $query = "UPDATE $wpdb->posts
	     SET
              post_modified = '$datetime'
             WHERE
              ID = '$post_id'";
    $wpdb->query( $query );

    $to = '[email protected]';
    $subject = 'Update to ' . get_the_title($post_id);
    $message = "There has been an update to your post " . $get_the_title($post_id) . "/n You can click to see this here:" . get_permalink($post_id);

    wp_mail($to, $subject, $message);
    
}
// run after ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 20);

This is untested mind, but it seems like it would work. Through using wp_mail() to send, it should follow standard site sending protocol (i.e. if you have an SMTP plugin or however your site sends by default).
