Corrigo emails are not received when a workorder is created and certain email is added as the custom contact

Hi Li,

We were working with adding a custom contact email for the ContactAt field while creating a workorder. Once the workorder is created, the contact email would receive an email from Corrigo with certain details of the workorder.

It has been observed these emails are coming through with a considerable delay and certain users reporting, them not receiving the email. Could you please let us know if there has been any changes in this functionality from Corrigo recently?

Please find the below payload that we are using to create a workorder. Please let us know if we are missing out on something?

{
    "Command": {
        "WorkOrder": {
            "Items": [
                {
                    "Asset": {
                        "Id": "125842",
                        "value": {}
                    },
                    "Task": {
                        "Id": 23457
                    },
                    "Comment": "This is test workorder with custom contact- Created by: [email protected] from Serve"
                }
            ],
            "TypeCategory": 4,
            "SubType": {
                "Id": 265
            },
            "Customer": {
                "Id": 198
            },
            "CustomFields": [],
            "ContactName": "Aparna",
            "ContactAddress": {
                "AddrTypeId": "Contact",
                "Address": "[email protected]"
            }
        },
        "ComputeSchedule": true,
        "EmergencyDisabled": true,
        "ComputeAssignment": true
    }
