Introduction: We might have a requirement to send emails from Workflow/cloud flows to Ids that cannot be resolved as Contacts, Accounts, Users in CRM.
We need to make changes to system settings to allow messages to unresolved recipients
In case of Workflow, directly add email address in the field( It will show ? as it is not resolved address)
For Cloud flow, in create a new email record, click on “Switch to Input entire array”, populate the email in addressused field.
This will let you send emails to an unresolved email address.
