Remove outdated contacts from email campaign suppression list

Your campaign spreadsheet contains outdated or unsubscribed emails that inflate lists and drive wasted sends. Keep campaign membership accurate so sends reach valid contacts before the next outreach.

Overview

For event marketers running invitation-only sends, stale addresses damage deliverability and waste outreach. This flow prunes campaign membership directly from your spreadsheet so your next invite list targets only valid contacts, preserving list hygiene ahead of each send.
