Add new newsletter subscribers to guest profiles by location

Newsletter signups lack location and birthday details, so staff can't personalize greetings. This adds signups to guest records with location and birthday for same-day offers.

Overview

When newsletter signups arrive without location or birthday context, store teams miss personalization and timely birthday outreach. This flow turns each subscriber into a guest record enriched with location and formatted birthday within minutes so your stores can send same-day offers and personalized greetings.
