Previously, Amazon Connect Outbound Campaigns relied solely on the customer's primary phone number to determine local time for message delivery. The update considers all phone numbers and addresses associated with a customer's profile to identify multiple time zones, ensuring messages are sent only during overlapping allowable time windows.
If a customer's contacts span different time zones, the system restricts outbound communications to times common across those zones or skips delivery when no overlap exists. This enhancement is integrated at no additional cost and is available in all AWS regions supporting the service, though no independent analyses of effectiveness were reported.
