Tata Communications’ CPaaS Drives Customer Continuity

Most enterprises do not have a customer communication problem. They have a customer continuity problem.

Tata Communications is trying to address that gap by moving its Communications Platform as a Service offer beyond individual messaging and voice use cases. Its Kaleyra acquisition gave the company a substantial programmable communications foundation. Its wider customer experience positioning now points to a bigger ambition: connecting communications, data, and automation so enterprises can run a more coherent customer journey.

Tata Communications also entered a leadership transition in 2026. Ganesh Lakshminarayanan was appointed Managing Director and CEO-designate in January and was due to succeed A.S. Lakshminarayanan following his retirement on April 13. The appointment places an executive with experience in enterprise technology, automation, AI, and digital transformation at the helm as Tata Communications expands its customer experience and communications proposition.

What’s the Actual Customer Engagement Problem Here?

Customer communications have become easier to send and harder to manage well.

That sounds counterintuitive, but it is the natural result of modern enterprise technology. A marketing team can launch a WhatsApp campaign. A product team can add an SMS verification step. A service operation can send a voice reminder. A contact center can handle an inbound call. Each interaction can be useful in isolation. The problem begins when the customer sees them as one relationship, while the enterprise still sees them as separate systems.

This is why customer engagement and journey orchestration has become a more important conversation than channel activation. The question is not whether a business can send a message. It is whether it knows that the customer has already received two messages, clicked one, opened a service case, changed their preference, or needs a human response rather than another automated notification.

Tata Communications CPaaS sits in the middle of that shift. The company’s CPaaS portfolio, strengthened by the 2023 acquisition of Kaleyra, includes messaging, voice, video, authentication, WhatsApp Business, and RCS capabilities. That gives enterprises a way to build real-time interactions into their applications and processes.

But a CPaaS platform on its own does not orchestrate a journey. It provides the pipes, APIs, and channels. The orchestration layer is what decides whether a customer should receive a message, which channel should be used, what content is appropriate, and what should happen after the customer responds.

A.S. Lakshminarayanan, former Managing Director and CEO at Tata Communications, said when the company completed the Kaleyra acquisition:

“Customer success and loyalty are pivotal to enterprise growth across industries and geographies.”

That is the right commercial framing. The issue is not that customers expect a business to have more channels. They expect the business to remember who they are and what has already happened.

What Does Tata Communications Actually Bring to the Table?

Tata Communications CPaaS brings a broad set of programmable communications capabilities, but the useful question for customer experience leaders is what they can do together.

SMS remains important for alerts, one-time passwords, appointment reminders, and time-sensitive notifications. WhatsApp Business gives organisations a familiar two-way messaging environment. RCS Business Messaging enables richer branded interactions in the native messaging inbox, including media and suggested actions. Voice and video can support high-value, complex, or assisted interactions. Verification capabilities can help make authentication part of the journey rather than a separate obstacle.

That is a credible foundation for omnichannel customer engagement. It allows an enterprise to build customer interactions around the nature of the task, not just the channel that happens to be easiest for the technology team to deploy.

For example, a bank may use SMS to verify a transaction, WhatsApp to answer a follow-up question, and voice or video when the customer needs detailed help. A retailer may use RCS for a product update, SMS for a delivery exception, and a service agent for a failed return. The channel is only one part of the decision. The customer’s current situation is the more important part.

Tata Communications’ broader positioning suggests it understands that distinction. Its Commotion CXP customer experience platform is described as connecting data, engagement, and automation to keep customer journeys moving. That is a more useful claim than simply promising more APIs, because it addresses the point where many enterprise communications strategies fail: the gap between an interaction occurring and the business knowing what to do next.

Why Does the Kaleyra Acquisition Matter Now?

The Kaleyra acquisition matters because it gave Tata Communications a more direct route into the programmable communications market at a time when CPaaS is becoming a strategic enterprise capability.

Historically, many businesses treated CPaaS as a narrow developer tool. A team needed to send a one-time password, launch an SMS campaign, or add a click-to-call button, so it called an API. That use case still exists. But the market is moving towards communication services that can support the complete customer lifecycle, from onboarding and verification to service, recovery, retention, and advocacy.

Juniper Research forecasts that global CPaaS revenue will reach $48.1 billion by 2029. Its research also puts the market on course to exceed $34 billion in 2026. The numbers do not prove that every enterprise needs the same CPaaS strategy. They do show that communications infrastructure is no longer a niche technology decision.

Tata Communications was also recognised in Juniper Research’s 2025 CPaaS Competitor Leaderboard. That is useful third-party validation, but it should not be the main reason to choose a provider. A buyer should care more about whether Tata Communications CPaaS can integrate with the systems that already control customer context: CRM, customer data platforms, contact center platforms, case-management tools, commerce environments, and identity services.

The acquisition also makes more sense when viewed alongside Tata Communications’ wider digital fabric strategy. The company is not trying to position communications as a standalone service. It is placing communications alongside connectivity, cloud, AI, and security. For large enterprises, that can be appealing because customer engagement rarely remains contained within a single SaaS application.

Why Channel Choice Still Needs Customer Context

Tata Communications CPaaS gives enterprises programmable access to channels such as SMS, RCS, WhatsApp, voice, video, and verification. That breadth matters only when the business can coordinate interactions across them.

For example, an enterprise may use SMS for urgent authentication, RCS for a richer transactional update, and WhatsApp for a two-way service conversation. However, the customer experience breaks down if each channel operates without shared identity, consent, and interaction history.

That is the central customer-continuity challenge. A rich RCS message is still unhelpful if it arrives after an issue is resolved. Similarly, a WhatsApp agent cannot deliver a seamless interaction if they cannot see the customer’s previous messages or contact-centre history.

This version keeps the relevance but removes the broad “could RCS and WhatsApp make engagement better?” framing. The section should sit after the overview of Tata Communications CPaaS capabilities, not as a standalone feature story about messaging channels.

What Would Actually Change for a CX Team?

For a CX leader, the real test is not whether Tata Communications CPaaS supports messaging, RCS, or WhatsApp. It is whether the platform helps remove the manual work of connecting customer interactions across teams and systems.

In a fragmented model, marketing owns outbound campaigns, product owns in-app notifications, customer service owns inbound conversations, security owns verification, and IT owns the integrations. The customer experiences all of them at once. No single team has a full view of what the customer has been sent, what they have done, or what needs to happen next.

A more connected CPaaS platform can change that operating model. It can make it easier to build common communication workflows and feed interaction events back into the systems that customer-facing teams already use. A delivered message, a click, a reply, an authentication failure, or an abandoned conversation can become a signal for the next stage of the journey.

That does not mean technology alone fixes the problem. A business still needs to agree who owns the journey, which customer signals matter, when communication should stop, and when a human must intervene. But the right technology layer can make those decisions executable across channels instead of leaving them trapped in a slide deck.

The most promising aspect of Tata Communications’ strategy is therefore not an individual channel. It is the possibility of bringing together the communications infrastructure and the broader customer experience infrastructure needed to make those channels act coherently.

What Should You Ask Before Choosing a CPaaS Platform?

Do not judge any CPaaS platform on the number of channels listed on its website. Judge it on whether it can make your own customer journeys more connected, measurable, and governable.

The organisations that get the most value from programmable communications will not be the ones that switch on every available channel.

They will be the ones that know where their customer journeys break today, have their customer data and consent practices in order, and can use a CPaaS platform to remove friction rather than add another communications silo.
