In a NetSuite connector, if the sync fails due an issue in the destination table (quota exceeded, partitions limits reach, etc) then Fivetran is not triggering the alert/notification of the failure.

This should work as a transaction, if the process fail at some point (extraction, load, process, destination, etc) Fivetran should mark the execution as failed and trigger the alert/notification so the users will know that something happened and the connector is not syncing data properly.
