Executing a view programmatically with input filters
I don't think that you need to execute the view programmatically. Because it's meaningless. Views just fetches data from the tables which you show and display it, it's all it does.
I think you need to alter Exposed Filter form and add your additional submit callback which on submission writes the searched strings into your custom table. And then you can query those table (from which table views fetch data.) with saved string as condition..
All of this logic must be run on cron job..

EDIT:
I don't know this can help you or not, but here is a very poor example. Not very performance friendly :). OPTIMIZE IT.

function MY_MODULE_form_views_exposed_form_alter(&amp;$form, &amp;$form_state) {
   if ($form['#id'] == 'MY_EX_FORM_ID') {
      if(user_is_logged_in()) {
         $form['actions'] = array(
            '#type' =&gt; 'actions',
         );

         $form['actions']['submit'] = $form['submit'];
         $form['actions']['subscribe'] = array(
            '#type' =&gt; 'submit',
            '#value' =&gt; 'Subscribe',
            '#submit' =&gt; array('my_ex_form_subscribe_submit'),
         );
         unset($form['submit']);
      }
   }
}


function my_ex_form_subscribe_submit($form, &amp;$form_state) {
   global $user;
   $account = clone $user;

   $input_val = $form_state['values']['field_adv_price_first']['min']; //Find your input field value and change this..

   db_insert('MY_SUBSCRIBE_TABLE')
      -&gt;fields(array(
         'uid' =&gt; $account-&gt;uid,
         'email' =&gt; $account-&gt;init,
         'input_val' =&gt; $input_val,
      ))
      -&gt;execute();
}


function MY_MODULE_cron() {
   $subscribed_query = db_select('MY_SUBSCRIBE_TABLE', 'mst');
   $subscribed_query
      -&gt;fields('mst', array('uid', 'email', 'input_val'))
      -&gt;execute()
      -&gt;fetchAllAssoc('id'/* id - is the primary key of MY_SUBSCRIBE_TABLE */);


   // Supposing that your view is querying for the node table to fetch jobs, by title field
   if(!empty($subscribed_query)) {
      foreach($subscribed_query as $key =&gt; $val) {
         $nids = db_select('node', 'n')
            -&gt;fields('n', array('nid'))
            -&gt;condition('title', '%' . db_like($subscribed_query[$key]['input_val']) . '%', 'LIKE')
            -&gt;execute()
            -&gt;fetchCol();

         if(!empty($nids)) {
            foreach($nids as $nid) {
               $node_url = url('node/' . $nid, array('absolute' =&gt; TRUE));
               $template = 'New job is found in our site and blablabla... &lt;a href="'. $node_url . '"&gt;BLABLABLA&lt;/a&gt;';

               // Suppose that you are using SwiftMail library.. You can use drupal's mail system as well. It's up to you
               $transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, 'ssl')
                  -&gt;setUsername('MYGMAILUSERNAME')
                  -&gt;setPassword('MYGMAILPASS');

               $mailer = Swift_Mailer::newInstance($transport);

               $message = Swift_Message::newInstance()
                  -&gt;setFrom(array('no-reply@'.$_SERVER['SERVER_NAME'] =&gt; 'MY-SITE.com'))
                  -&gt;setTo(array($subscribed_query[$key]['email']))
                  -&gt;setBody($template, 'text/html');
               $mailer-&gt;send($message);
            }
         }
      }
   }
