How to prevent term URL in webform email template (Webform References Module)?
When returning field value Webform References Module, add link to field output using theme function (theme_webform_display_term_reference_field()), which you can override in your theme's template.php and then clear Site Cache. Check sample code below, which you can write in your theme's template.php:

/**
 * Format the output of data for this component.
 */
function [THEME_NAME]_webform_display_term_reference_field($variables) {
  $values = (array) $variables['element']['#value'];
  $items = array();
  foreach (array_filter($values) as $value) {
    $tid = check_plain($value);
    if ($tid) {
      // Do not pass 2nd argument, keep it default i.e. FALSE.
      $items[] = _webform_references_get_term_name($tid);
    }
  }
  $output = count($items) &gt; 1 ? theme('item_list', array('items' =&gt; $items)) : (isset($items[0]) ? $items[0] : '');
  return $output;
}


NOTE : This will also remove the Term field link on view submission page.
