Add updated spreadsheet contacts to service mailing list

Your contact sheet holds opt-ins and preferences, but manual edits cause misflagged subscribers. Keeps your email audience current so campaign managers get accurate segments within minutes.

Overview

If spreadsheet updates aren't reflected in your mailing lists, campaigns go to the wrong audience and segmentation breaks down. This flow keeps contact records and opt-in flags synchronized automatically so campaign managers get accurate segments within minutes and avoid mis-sends.
