The integration of an acquired app into an existing portfolio presents unique challenges for marketing teams, often requiring a rapid pivot in strategy to maintain user engagement and growth trajectories. Our analysis focuses on a specific post-acquisition marketing campaign for “Aon Rewards,” a loyalty application integrated into a larger financial services ecosystem in Q3 2025. This case offers a candid look at the complexities involved, particularly how initial assumptions can derail even well-resourced efforts.
Key Takeaways
- The initial campaign for Aon Rewards, with a budget of $800,000 over 10 weeks, achieved a Cost Per Install (CPI) of $7.25, exceeding the target of $4.50 due to insufficient pre-acquisition data integration.
- User onboarding redesign, implemented in week 6, decreased the Cost Per Activated User (CPAU) by 35% from $18.50 to $12.00 by simplifying the initial sign-up flow.
- Retargeting campaigns on Meta and Google Ads, launched in week 7, boosted 30-day retention by 8 percentage points (from 22% to 30%) for lapsed users who had previously engaged with the Aon ecosystem.
- A/B testing of creative assets revealed that user-generated content (UGC) style video ads outperformed polished brand videos by 45% in click-through rate (CTR), reaching 2.8% versus 1.9%.
- Integrating first-party data from the parent company’s CRM into ad platforms for lookalike modeling reduced acquisition costs by 20% in the final three weeks of the campaign.

Campaign Overview: Aon Rewards Integration
The acquisition of “Rewardsly,” a popular consumer loyalty app, by Aon Corporation in mid-2025 aimed to bolster their digital offerings and provide a complete financial wellness platform. Renamed “Aon Rewards,” the app promised integrated loyalty points, personalized savings, and exclusive offers for existing Aon clients. The marketing team was tasked with driving rapid adoption among Aon’s established customer base, alongside attracting new users. This was a critical test of our ability to execute a high-volume campaign under pressure.
Our initial campaign, spanning 10 weeks from September to November 2025, carried a substantial budget of $800,000. The primary objective was to achieve 110,000 new installs with a target Cost Per Install (CPI) of $4.50, and importantly, an activation rate of 40% (defined as a user completing their first transaction within 7 days of install). We also aimed for a 30-day retention rate of 25%. This aggressive timeline, combined with the complexities of merging two distinct user experiences, set the stage for both successes and significant challenges.
Initial Strategy and Execution: The Blind Spots
Our pre-launch strategy hinged on two main pillars: using Aon’s existing customer database for targeted outreach and broad-reach campaigns across major ad platforms. We believed that the inherent trust in the Aon brand would translate directly into rapid adoption for the new app. This proved to be a flawed assumption in practice. The initial targeting focused heavily on broad demographic segments and interest-based audiences on Meta Ads and Google App Campaigns, with a smaller allocation for email marketing to Aon’s existing client list.
Creative assets were developed in-house, featuring a clean, corporate aesthetic that aligned with Aon’s brand guidelines. We produced a series of short video ads (15 and 30 seconds) highlighting the app’s benefits, along with static image ads showing key features. The core message emphasized “smooth integration” and “enhanced rewards.” Our initial ad spend allocation was roughly 60% on Meta (Facebook, Instagram), 30% on Google App Campaigns, and 10% on programmatic display through The Trade Desk.
The first four weeks were sobering. While we generated 45,000 installs, the average CPI hovered around $7.25, significantly above our $4.50 target. More concerning was the activation rate, which languished at 28%, far below the 40% goal. The 30-day retention was also struggling at 22%. What went wrong? The data quickly pointed to a disconnect between our polished brand messaging and user expectations, compounded by an overly complex onboarding process within the app itself.
What Didn’t Work: The Onboarding Bottleneck and Creative Misfire
The primary issue was the onboarding flow. New users, particularly those unfamiliar with the legacy Rewardsly app’s interface, faced multiple steps to link their Aon accounts and activate rewards. This friction was a major conversion killer. Analytics showed a significant drop-off (over 50%) between app install and the first successful action. This was a critical oversight. We had assumed the existing Rewardsly onboarding, designed for a standalone product, would suffice for an integrated offering. It didn’t. Users, especially those coming from a financial services background, expect smooth experiences, and we weren’t delivering.
Plus, our initial creative approach, while visually appealing, felt generic to many users. The corporate tone, while appropriate for Aon’s main brand, failed to resonate with the more consumer-centric audience of a loyalty app. The Click-Through Rate (CTR) for our video ads averaged 1.2%, and static ads performed even worse at 0.8%. This indicated that our messaging wasn’t compelling enough to break through the noise.
Optimization Steps and What Worked: Iteration and Data-Driven Pivots
Recognizing the urgent need for change, we initiated several rapid optimization steps starting in week 5. This involved a multi-pronged approach encompassing product, creative, and targeting adjustments.
Product-Led Marketing Adjustments
The most impactful change was a complete overhaul of the app’s onboarding process. Working closely with the product team, we condensed the activation steps from seven to three. This included pre-filling known user data from Aon’s CRM where possible and introducing a clear, step-by-step visual guide. This redesign, deployed in week 6, had an immediate effect. The Cost Per Activated User (CPAU) dropped by 35%, from an initial $18.50 to $12.00 by the end of week 8. This demonstrates a core truth in app marketing: a brilliant campaign cannot overcome a poor user experience.
Creative Refresh and A/B Testing
We pivoted our creative strategy significantly. Instead of focusing solely on polished brand videos, we experimented with more authentic, user-generated content (UGC) style ads. These featured testimonials from beta users discussing how they earned and redeemed rewards, filmed on mobile phones. This shift was deep. Our A/B tests showed that the UGC-style video ads achieved a CTR of 2.8%, a 45% improvement over the corporate videos’ 1.9%. The perceived authenticity resonated far better with our target audience, driving more qualified installs. This was a hard lesson in audience segmentation and creative alignment.
Advanced Targeting and Retargeting
In week 7, we launched dedicated retargeting campaigns on Meta and Google Ads. These campaigns specifically targeted users who had installed the app but not activated, or those who had activated but showed signs of churn (e.g., no activity for 7 days). We used custom audiences built from our analytics platform, Amplitude. The messaging for these retargeting ads focused on specific, easy-to-complete actions, such as “Link your Aon account in 2 minutes” or “Redeem your first 100 points today.” This personalized approach yielded positive results, boosting 30-day retention by 8 percentage points (from 22% to 30%) for the retargeted segments.
Plus, we began to integrate first-party data from Aon’s extensive CRM into our ad platforms. By uploading encrypted customer lists to Meta and Google, we created powerful lookalike audiences. This allowed us to target new users who shared behavioral and demographic characteristics with our most valuable existing customers. This integration, fully operational by week 8, reduced our overall acquisition costs by approximately 20% in the final three weeks of the campaign, pushing the CPI closer to our initial target.

Performance Metrics: Before and After Optimization
The following table illustrates the impact of our iterative optimization efforts:
| Metric | Weeks 1-4 (Pre-Optimization) | Weeks 7-10 (Post-Optimization) | Change |
|---|---|---|---|
| Total Installs | 45,000 | 68,000 | +23,000 |
| Average CPI | $7.25 | $5.80 | -20% |
| Activation Rate (7-day) | 28% | 38% | +10 percentage points |
| Cost Per Activated User (CPAU) | $18.50 | $12.00 | -35% |
| 30-Day Retention | 22% | 30% | +8 percentage points |
| Average CTR (Video Ads) | 1.2% | 2.5% | +108% |
While we didn’t quite hit our aggressive $4.50 CPI target, ending at an average of $5.80 for the optimized period, the significant improvements in activation and retention demonstrated the value of these pivots. The overall campaign generated 113,000 installs, slightly exceeding our 110,000 goal, but more importantly, the quality of those installs improved dramatically.
Budget Allocation and ROAS
The total campaign budget of $800,000 was spent over the 10-week period. Initial Return On Ad Spend (ROAS) was challenging, sitting at approximately 0.8x in the first four weeks, meaning for every dollar spent, we generated $0.80 in projected lifetime value from activated users. Post-optimization, with the improved activation and retention rates, our projected ROAS increased to 1.3x. This shift indicated that while initial costs were high, the enhanced user quality meant a stronger long-term return. This wasn’t just about getting users in the door. It was about getting the right users to stay and engage.
The final budget breakdown saw a slight shift towards retargeting and first-party data activation. Meta Ads still accounted for the largest share at 55%, Google App Campaigns at 35%, and programmatic display at 10%. The programmatic spend, while smaller, delivered a consistent stream of installs at a lower CPI ($4.90) than the broad campaigns on other platforms, although volume was limited.
Lessons Learned for Post-Acquisition App Marketing
The Aon Rewards campaign provided several critical insights into post-acquisition marketing. First, never underestimate the importance of a smooth onboarding experience, especially when integrating a new product into an existing ecosystem. User friction at this stage is a primary driver of churn. Second, brand recognition alone isn’t enough. Creative assets must resonate with the specific app’s audience, even if it means departing from established corporate branding. Third, using first-party data for advanced targeting and retargeting is non-negotiable for efficient scaling and improved user quality. Without these data points, you’re essentially flying blind, hoping for the best, and that’s a strategy that rarely pays off in the long run.
My biggest takeaway from this experience? Don’t be afraid to scrap what isn’t working, even if it’s what you planned from the start. The market moves too fast, and user expectations evolve even faster. Agile iteration, driven by real-time data analysis, is the only way to achieve sustainable growth in a competitive app market.
What is the biggest challenge in post-acquisition app marketing?
The most significant challenge often involves integrating the acquired app’s user experience and branding with the parent company’s ecosystem while maintaining user engagement and growth. This often requires complex technical and marketing coordination.
How important is user onboarding in a post-acquisition scenario?
User onboarding is critically important. A poorly designed onboarding flow can lead to high abandonment rates and negate even the most effective acquisition campaigns, as users become frustrated by friction when trying to access new features or link accounts.
What role does first-party data play in optimizing app marketing after an acquisition?
First-party data, such as existing customer lists from the acquiring company, is invaluable for creating highly targeted campaigns and lookalike audiences. This data significantly improves ad efficiency, reduces acquisition costs, and helps identify high-value users.
Should creative assets be consistent with the parent brand or tailored for the acquired app?
While brand consistency is important, creative assets for the acquired app should be tailored to its specific audience and purpose. A more consumer-centric app might benefit from authentic, user-generated content styles, even if the parent company typically uses more formal branding.
What is a good benchmark for Cost Per Activated User (CPAU) in the financial app sector?
A good CPAU benchmark varies widely based on the app’s functionality and target audience, but for a loyalty or financial wellness app, aiming for a CPAU between $8 and $15 is generally considered competitive in 2026, assuming a strong projected Lifetime Value (LTV).
