Incoming emails from web form

Incoming emails from web form

Hello,

We receive incoming emails from our public webpage. This email is always the same. Is there a way to extract the senders email from the submitted form and replace it in the Email field in Zoho Desk? Otherwise an agent will always need to go in and manually put in the senders email. 

For example, the form looks like this:

Name: John Doe

Email: email@email.com

Phone: 555-555-1111

Company: Great


This will get forward from our webpage email into Zoho Desk, the ticket will populate with our webpage email. I would like to extract John Doe's email and inserted into the ticket. 
Thanks for your time!
