We are looking to promote our new search engine by allowing users to enter a search term in the email and then search for that on our site.

Has anyone tried this? What has been the feedback? Pros/cons?

Per NDA im using Bing for the example

<form action="http://www.bing.com/?q=" method="get">  
<input type="text" name="q" value="pizza near me" style="padding:10px;font-size:15px;color:grey;">  
<input type="submit" value="Search Now!" style="padding:12px;background-color:#1d4c87;color:white;border:none;">  
</form>

Thank you for your help.
