Deloitte's Customer Service Excellence 2025 report, surveying 235 customer service leaders globally, finds that email and phone remain the dominant contact channels at 89 and 87 per cent usage. Proactive messaging, the channel with the highest customer satisfaction scores, remains among the least invested in. For Irish organisations, the path to an effective omnichannel experience is not adding more channels but aligning each contact reason to the channel best suited to it.

The Deloitte findings reframe channel investment as a customer experience design decision rather than a technology one. Three opportunities define the cx strategy case: self-service capability is growing but falling short of customer demand; proactive messaging is the highest-performing underinvestment; and increasing the frequency of customer satisfaction measurement is the most accessible improvement available.

Self-service demand is rising but quality is lagging. Deloitte finds that 48 per cent of organisations report increased self-service usage, yet only eight per cent rate their capabilities as excellent and 27 per cent rate them as poor. Issue reporting, order queries, and product information, the top three contact reasons globally, are all resolvable through well-designed digital customer experience journeys. Building self-service content around actual contact reasons converts demand into resolution and reduces inbound volume.

Proactive messaging is the biggest underinvestment in Irish customer service channel design. Deloitte shows it produces higher customer satisfaction and employee satisfaction than any reactive channel. CCMA Ireland benchmarking records outage and billing notifications as primary inbound contact drivers for Irish utilities and telecoms, making proactive outreach the most direct route to reducing contact volume and building customer loyalty. Using voice of the customer data to identify the highest-volume preventable contacts is the logical starting point.

Measurement frequency is the most immediately accessible lever for improving customer satisfaction. Deloitte finds that organisations analysing customer insights in real time score significantly higher on customer experience than those reviewing feedback monthly or quarterly. The customer effort principle established by Harvard Business Review confirms that reducing contact effort, rather than adding service gestures, is the strongest predictor of loyalty and repeat engagement. Frequent effort score measurement is the operational foundation.

Three steps would allow Irish CX leaders to act on the channel optimisation opportunity. First, map the top ten contact reasons using CCMA Ireland data and audit whether each is routed to the channel best suited to resolve it. Second, pilot proactive messaging for the two highest-volume preventable contacts and measure the satisfaction impact through CXi Ireland. Third, shift customer insights analysis to at minimum a weekly cadence as the foundation of a genuinely customer centric strategy.

The Deloitte 2025 report makes plain that service excellence in customer service is a function of channel fit, not channel volume. Irish organisations that redesign their omnichannel experience around contact reason data, invest in proactive outreach, and measure customer satisfaction more frequently will improve across every dimension the report tracks. The customer experience gains are structural and measurable, and in 2026 the data to act on them is already within reach for every Irish organisation.
