Add new account signups to welcome list and alert spam

Signup webhooks arrive without marketing context, leaving welcome emails untriggered. Campaign managers can onboard learners within minutes; the workflow tags subscribers and flags suspicious signups.

Overview

When learners sign up, marketing needs clean contacts and immediate outreach; this flow captures and tags signups so welcome campaigns start within minutes. Suspicious signups are routed to a review channel, reducing noise and keeping onboarding on schedule.
