This page provides channel-specific examples of Group-Level Unification (GLU) in action. For an overview of how GLU works and its core use cases, see Use Cases for Group-Level Unification.
GLU is available across Email, Web Push, SMS, WhatsApp, and App Push. Each channel can be activated at the group level.
Industry: Retail
Group-level signal: User has not purchased on any connected brand in the last 90 days.
Without GLU: Each brand independently identifies its own lapsed users and sends a reactivation email. A user connected to three brands receives three overlapping emails, often within the same send window, with no awareness of the other brands' sends.
With GLU: The audience is defined once at the group level. A single, coordinated email is sent from the most relevant brand, personalized with the user's last-viewed product category, even if that category was browsed on another brand's site.
Outcome: Reduced email fatigue, cleaner suppression logic, and personalization that reflects the user's full relationship with the group, not just one brand's view.
SMS
Industry: Financial services
Group-level signal: User received an SMS from Brand A within the last 48 hours.
Without GLU: Brand B has no visibility into Brand A's SMS sends. Both brands operate their own frequency caps independently, and a user can receive multiple promotional SMS messages from the same group within a short window.
With GLU: Before Brand B sends a promotional SMS, its audience automatically excludes users who received an SMS from Brand A within the last 48 hours. Frequency capping is enforced at the group level, not per brand.
Outcome: Fewer opt-outs, stronger deliverability, and a more considered send cadence across the group.
Industry: Travel
Group-level signal: User browsed flights on Brand A and hotels on Brand B within the same session window.
Without GLU: Brand A sends a flight booking reminder. Brand B sends a hotel booking reminder. The user receives two disconnected messages with no awareness of their combined trip intent.
With GLU: A single WhatsApp message is triggered based on activity across both connected brands. The message reflects the user's full trip intent — flight and hotel — in a single, coherent nudge.
Outcome: Higher conversion on booking reminders and a significantly better user experience for multi-brand trip planners.
Web Push
Industry: Commerce
Group-level signal: User is a Gold-tier loyalty member (attribute stored on the parent panel). The user is actively browsing a brand's site that does not have this attribute locally.
Without GLU: The local brand has no access to the user's loyalty tier. Web Push messages are generic and cannot reference group-wide status or exclusive benefits.
With GLU: When a Gold-tier customer browses any brand's site, Web Push can surface the loyalty tier and trigger an exclusive offer, even if the local brand has never captured that attribute independently.
Outcome: Personalization reflects the customer's full relationship with the group, not just a single brand's interaction history. Loyalty benefits become a group-wide retention tool rather than a single-brand one.
App Push
Industry: Media
Group-level signal: User subscribes to the news app (Brand A) and has engaged with sport content on the sport app (Brand B).
Without GLU: The sport app cannot identify users from the news app. Cross-sell or behavioral routing between apps is not possible without a manual data sync.
With GLU: A news app subscriber who has also engaged with sports content on another brand's app receives a Mobile App Push highlighting a relevant live event. GLU resolves which app to send to and which behavioral data to use, based on the unified profile across both panels.
Outcome: The right user receives the push in the right app, based on unified cross-brand behavior, without requiring a manual audience export or third-party identity resolution.
