Did you ever get a solution for this?

I would like to edit the email that is being sent. Any solution? 

Hi,

Not getting the exact question, you said its an email template but it should be a qweb template.

If you want to modify the template then you need to inherit the Contact Us thank template as per your custom requirement using xpath.

Thanks.

Hi Mohammed:

Is this an email that is being sent out or are you referring to the message that is displayed on the website after submitting the Contact us form ?
