title: Can I use custom html-css-js form within an Email?
body: <p>I need to insert my own form in a gmail email, so that my client can fill that form, press a submit button and trigger a response with the form content to my domain. 
  I already did the template (example image below) and successfully sent the email with it using python gmail API by inserting the html code in the body. My question is the following: Once the user completes the form, how do I get the info in my domain server? Maybe by doing an ajax request when the button is pressed? </p>
  
  <p>Help will be much appreciated!</p>
  
  <p>Thank you!!</p>
  
  <p>Template example:
