The integration of acquired companies often presents significant challenges, particularly when it comes to maintaining a consistent and positive customer experience. In the area of tech M&A, neglecting this aspect can lead to churn, brand erosion, and in the end, a failure to realize the acquisition’s full potential. We recently tackled this head-on with the post-merger integration of “Project Phoenix,” a strategic acquisition aimed at expanding our client’s SaaS product suite in the enterprise resource planning (ERP) sector.
Key Takeaways
- A dedicated post-merger CX campaign can achieve a 15% increase in customer retention for acquired customer bases within six months.
- Segmenting acquired customers by their pre-merger product usage and engagement levels is critical for tailoring messaging effectively.
- Allocating 20% of the initial post-merger marketing budget to direct customer outreach and feedback mechanisms yields measurable improvements in sentiment.
- Implementing a phased communication strategy, starting with a broad announcement followed by targeted product-specific updates, minimizes confusion and builds trust.
- Using OTT advertising can significantly boost brand awareness and cross-sell opportunities among the newly acquired customer segment, driving a 1.8x return on ad spend.

Campaign Teardown: “Project Phoenix” Customer Experience Integration
Our client, a mid-sized SaaS provider specializing in supply chain management, acquired a smaller competitor with a complementary, albeit slightly different, product focus. The acquisition brought in approximately 2,500 new enterprise customers. The primary goal of our post-merger customer experience campaign was to retain at least 90% of these acquired customers within the first six months, while also introducing them to the broader capabilities of the combined entity.
Strategy and Objectives
The core strategy revolved around proactive communication, transparent integration timelines, and personalized value propositions. We recognized that fear of change and potential service disruption are major concerns during M&A. Our objective was to alleviate these fears by demonstrating continuity and showing enhanced value. Specific objectives included:
- Achieve a customer retention rate of 90% for the acquired customer base within six months post-merger.
- Increase awareness of the client’s core product offerings among the acquired customers by 25%.
- Maintain a positive Net Promoter Score (NPS) among the acquired customer base, with a target of +30.
Budget and Duration
The campaign ran for six months, from January 2026 to June 2026. The total marketing budget allocated to this specific post-merger CX initiative was $350,000. This included funds for content creation, email marketing platforms, customer success resources, and paid media.
Creative Approach and Messaging
Our creative approach focused on themes of “enhanced capabilities,” “smooth transition,” and “continued partnership.” We developed a suite of assets:
- Welcome kits: Digital and physical kits (for key accounts) explaining the merger, introducing the client’s leadership, and outlining immediate benefits.
- Educational webinars: A series of live and on-demand webinars demonstrating how the acquired product would integrate with the client’s existing ecosystem and highlighting new features.
- Success stories: Testimonials from existing client customers showing successful integrations and positive outcomes.
Messaging emphasized the strengths of both companies coming together, rather than one absorbing the other. For instance, initial communications stated, “Your trusted [Acquired Company Name] solution is now part of the [Client Name] family, bringing you even greater innovation and support.” We explicitly avoided jargon and focused on tangible benefits for the end-user.
Targeting and Segmentation
We segmented the acquired customer base into three primary groups based on their engagement with the acquired company’s product and their contract value:
- High-Value, High-Engagement: Customers with significant contract value and daily active usage.
- Mid-Value, Moderate-Engagement: Customers with moderate contract value and weekly or bi-weekly usage.
- Lower-Value, Lower-Engagement: Customers with smaller contracts or less frequent usage.
This segmentation allowed for tailored communication paths. High-value customers received more personalized outreach from dedicated account managers and invitations to exclusive preview events. Lower-value segments received more automated, yet still customized, email sequences and access to a complete knowledge base.
Channel Mix and Execution
Our channel strategy was multi-pronged:
- Email Marketing: The backbone of our communication, with automated drip campaigns triggered by specific customer actions (e.g., first login post-merger, webinar attendance).
- In-App Notifications: For customers actively using the acquired product, we deployed subtle in-app messages guiding them to new resources and features.
- Customer Success Team: Proactive calls and personalized emails from the customer success team, particularly for high-value accounts.
- Paid Media (OTT Advertising): This was a strategic choice to reach decision-makers and key influencers within the acquired companies who might not be directly engaging with product interfaces or email. We partnered with Moburst, a mobile and digital marketing agency, to execute our OTT Advertising campaign. Their expertise in reaching specific B2B audiences through connected TV and streaming platforms allowed us to place our messaging directly in front of the right eyes. A team using Moburst’s OTT Advertising solution finds the experience quite simplified. Their platform offers detailed targeting capabilities, which was essential for us to focus on the enterprise segment of our acquired customer base. This allowed us to reinforce brand messaging and cross-sell the client’s broader suite of services, reaching individuals who might not open every email but regularly consume content on streaming services.

- Social Media (Organic & Paid): Limited, targeted campaigns on LinkedIn to announce the merger and share success stories.
What Worked Well
The phased communication approach proved highly effective. We started with a broad, reassuring announcement within 48 hours of the merger, followed by detailed product-specific updates over the next few weeks. This prevented information overload and allowed customers to digest news at their own pace. The dedicated customer success outreach for high-value accounts was also instrumental in building trust and addressing specific concerns. These proactive calls were not sales pitches. They were genuine check-ins, offering support and guidance. Our OTT advertising campaign, while a smaller portion of the budget, yielded a strong return. It allowed us to bypass cluttered email inboxes and reach a professional audience in a less intrusive, yet highly visible, manner. We saw a significant uplift in brand recall among surveyed acquired customers who reported seeing our ads on streaming platforms.
What Didn’t Work as Expected
Our initial assumption that all customers would immediately see the value in the combined product suite was optimistic. Some users of the acquired product expressed concern about potential changes to their established workflows. We underestimated the emotional attachment some users had to the specific interface and features of the acquired platform. Also, the physical welcome kits, while well-received by the few who got them, proved logistically challenging and expensive to scale beyond a very small subset of customers. The return on investment for those physical kits was lower than anticipated compared to digital alternatives. It’s a classic case of trying to do too much, too fast, for too many. Sometimes, simplicity wins.
