Customized Email on Form Submissio

Hey Guys,

I managed to create Email Notifications for when a user submits a form on my website using SendGrid.

I wanted to customize the email in order to send the user something like:

Dear {{User Name}}

Thank you for your subscription. Your Email has been recorded with us.
We invite you to visit our Online Store at www.xyz.com

Thank you,
My Team Name

Currently it only shows the name and email like this:

Name: {{User Name}}
Email: {{User Email}}
