I have 2 projects. Project A has an automation that triggers a task to be created in Project B. Part of the automation task creation includes the fields (Assignee, Description, Linked Issues, and Reporter). 
The task is created in Project B. The 4 fields are populated with the original information from Project A.

I can reply to the customer in Project A (originating issue) and it will email the customer. When I reply to the customer in Project B (issue created from automation), the customer does not receive the email.
How can I get the Project B request to send the email to the customer?
