Is there a way to get a default e-mail recipient by default when adding a new webform node?
You can do this with a custom module and hook_node_presave(). After you have a custom module created, you can use code like this to create a default e-mail configuration for any created Webforms.

Assuming your module were called myexample.module, the hook would look like this:

&lt;?php
/**
 * Implements hook_node_presave().
 */
function myexample_node_presave($node) {
  // Add a default e-mail configuration for new nodes.
  if (empty($node-&gt;nid) &amp;&amp; $node-&gt;type == 'webform') {
    $node-&gt;webform['emails'][] = array(
      'email' =&gt; 'example@example.com',
      'subject' =&gt; 'default',
      'from_name' =&gt; 'default',
      'from_address' =&gt; 'default',
      'template' =&gt; 'default',
      'excluded_components' =&gt; array(),
      'html' =&gt; 0,
      'attachments' =&gt; 0,
    );
  }
}
