Please bring back the ability to send email notifications to more than one customer.

Hi.  It used to be possible to send shipping notification emails to more than one email address, separated by a comma in the Ship To box. This is no longer true unfortunately.  Please bring this back!  We are stuck with an unfortunate manual work-a-round because our old shipping software had this ability and ShipStation does not.

See support case 3830555.
