Add updated spreadsheet rows to email subscriber list

Your sheet's new contact emails sit unprocessed, causing missed or duplicate campaign sends. It adds and deduplicates subscribers so campaigns go out on time.

Overview

If subscriber collection relies on manual copying from spreadsheets, campaign managers spend hours fixing lists and sends risk going out late. This flow moves new or changed sheet rows into your mailing list, normalizes addresses, and delivers a clean audience within minutes so campaigns launch on schedule.
