Our customer service team receives an email notification every time the website contact form is submitted. This is now sent via Marketing Cloud's transactional messaging API.
The email is 'from' a specific sender profile but as these notifications are being used for email-to-case functionality in Salesforce Service Cloud, the case is always created against our sending email address. Previously, a transactional email service was used that would use the customer's email address as the 'from' address.
Am I correct in understanding there is no way to replicate this in Marketing Cloud as while it's possible to dynamically populate the from email address, this has to be verified?
