Weird code in emails

Weird code in emails

So when we gan email from the ticket system we seem too get this weird stuff at the top (changed our domain in the url)

{ "@context": "http://schema.org", "@type": "EmailMessage", "potentialAction": { "@type": "ViewAction", "target": "https://desk.zoho.eu/support/mydomain/ShowHomePage.do#Cases/dv/131010000000368025", "name": "View Ticket " }, "description": "View Ticket" }

The customer sees this as well when they get an email. How do we resolve this.

Thanks
