Drive Smarter Customer Connections for Retail with Acudo

A leading UK supermarket group requires a solution to validate millions of customer phone numbers collected through loyalty programmes, e-commerce orders, and in-store promotions.

Their goal? To create a single source of truth for customer contact data, enabling more accurate communications, improved campaign ROI, and seamless omnichannel customer experiences, all whilst meeting strict GDPR and data protection requirements.

Retailers and supermarkets face three major challenges in maintaining customer contact accuracy:

1. Data decay and duplication

Customer details change frequently as people move, switch networks, or change numbers. Outdated contact data leads to failed communications and wasted spend.

2. Real-time validation at scale

Data is captured across multiple touchpoints: loyalty signups, delivery forms, online accounts, in-store kiosks; all requiring instant validation without slowing down the customer journey.

3. Fragmented data infrastructure

Customer records often sit across marketing systems, CRM tools, and third-party partners, making unified validation complex and time-consuming.

Additionally, many retail teams lack telecom expertise, making traditional validation tools difficult to interpret and integrate effectively.

Acudo integrates seamlessly into existing retail ecosystems, connecting with CRM platforms, loyalty systems, and customer engagement tools through both real-time APIs and bulk upload processing.

This enables retailers to:

• Instantly validate customer mobile numbers at signup, checkout, or during data imports.
• Automate cleansing of large datasets across loyalty databases and marketing lists.
• Standardise outputs, so every number is clearly marked as live, inactive, or ported, even for non-technical teams.

This hybrid approach provides retailers with a continuous cycle of data accuracy, ensuring customer communications always reach the right person, in the right place, at the right time.

For existing customer datasets and loyalty databases, Acudo’s bulk upload portal enables:

• High-volume uploads across multiple file formats (CSV, XLSX, etc.).
• Parallel processing of millions of customer records with consistent speed.
• Scheduling and pausing of uploads for flexibility around retail trading hours.
• Full data integrity, with validation results aligned to original customer data.
• Real-time progress visibility and downloadable reports for internal auditing.

1. Improved data quality

By validating approximately 20 million customer records, supermarkets may identify 15% invalid or unreachable numbers, dramatically improving message deliverability and customer engagement rates.

2. Significant cost savings

Removing invalid numbers reduces wasted SMS and push campaign spend by 18%, saving thousands monthly, while ensuring messages only reach genuine customers.

3. Enhanced customer experience

Real-time validation at signup prevents incorrect entries and duplicate accounts, improves checkout experience and loyalty scheme accuracy.

4. Marketing efficiency

Cleaner data means higher open rates, improved segmentation accuracy, and reduced churn in loyalty campaigns, which drives measurable ROI on marketing spend.

5. Long-term scalability

Acudo’s integration provides a foundation for data-driven personalisation, supporting future AI-driven marketing and customer analytics.
