Raise ticket automatically when email is received.

Hi there,
 
When you set up Zendesk Support, you have one related email address: support@yoursubdomain.zendesk.com. Emails received at this address become tickets. 
 
Also, you can provide your users with alternative email addresses for submitting tickets. These addresses are known as support addresses. And when a customer sends an email to your support email address, a ticket is created in Zendesk Support.
 
For more information, please see this article:
 
Adding support email addresses for users to submit tickets
 
I hope this helps! Thank you.
