Sending an Email to Multiple Relative Recipients
You can define a Workflow Policy that sends the same email to multiple recipients.
To send an email to multiple relative recipients
Define an action for the policy program.
In the Recipients list, add a new record, set the Type field to Send to Relative, then select the name of the first recipient in the Name field.
Repeat step 2 to add each additional recipient, updating the Name field for each recipient.
Associate the action with the Workflow Policy.
