Add SMS opt-out flag from updated spreadsheet rows

Your campaign spreadsheet can list contacts who should skip SMS, causing accidental texts and compliance gaps. Flagging those contacts as opted-out keeps campaigns compliant the same day.

Overview

If spreadsheet flags don't reach your messaging system, campaigns risk sending unwanted SMS and failing compliance. This flow converts sheet updates into immediate opt-out flags so campaign managers avoid accidental sends and keep lists compliant the same day.
