Sinch forecasts a major shift in digital communication by 2026, driven by the convergence of artificial intelligence, voice technology, and conversational messaging. The company anticipates that global message traffic will increase up to fivefold across industries as brands adapt to new expectations in customer engagement and security standards.
Communication surge
According to Sinch, as conversational AI becomes more deeply integrated, businesses and consumers will engage in entirely new forms of digital interaction. With AI agents increasingly able to communicate directly with one another, total conversation volumes are expected to surge. This will likely require companies to build new data and workflow architectures to manage vast numbers of parallel, context-rich exchanges.
"Sinch powers over 900 billion interactions every year for 190,000 businesses, reaching virtually every mobile phone on the planet. That scale gives us a unique view of where the world is heading. Our predictions aren't theory, they're grounded in real data and billions of live conversations showing how AI, messaging and trust are reshaping communication," said Daniel Morris, Chief Product Officer, Sinch.
New business models
AI agents are expected to transition from tools for cost reduction to engines for business growth. Sinch notes that leading companies already see up to 30% higher order value from post-resolution upsells managed by AI agents. Customer interactions, traditionally seen as operational expenses, are fast becoming strategic opportunities for generating insights and incremental revenue.
Voice technology rise
Voice AI is becoming increasingly sophisticated, now responding in approximately 800 milliseconds. Sinch predicts that this technology will soon be the preferred channel for customers who need to resolve complex issues, offering a more responsive and context-aware experience that closely mimics human conversation.
Messaging expectations
SMS will maintain its importance for reach and verification, but growth is expected in more dynamic messaging channels such as RCS and WhatsApp. Sinch believes these platforms will allow brands to move beyond one-way notifications to develop more personalised, two-way customer journeys driven by AI. Companies that integrate these channels into a unified customer experience layer will be well-placed to meet changing market expectations.
Customer journeys
Modern consumers are expected to demand seamless movement across devices and channels, with context preserved at every touchpoint. Sinch warns that organisations unable to synchronise communications-whether through voice, chat, or email-risk losing relevance as customer loyalty shifts towards brands providing fully connected experiences.
Regional strategies
Messaging usage varies sharply by region. WhatsApp dominates business-to-consumer messaging in markets such as Brazil and India, while RCS is gaining ground in North America and so-called super apps shape communication patterns in parts of Asia. Sinch highlights that global companies need to accommodate regional differences while maintaining both compliance and performance.
Security standards
With the proliferation of deepfake and voice spoofing threats, the need for verified and secure communication is becoming more pressing. Sinch forecasts that digital trust will increasingly rely on technology such as verified senders, branded visuals, and invisible authentication layers. The firm believes that irrelevant or unverified content will be filtered out before reaching end users.
Email transformation
Consumer expectations for email are also shifting. Research cited by Sinch shows that 42% of consumers expect personalised promotions via email, while a third become frustrated by irrelevant messages. Intelligent inboxes will begin to penalise generic content, essentially making messages that lack trust or personalisation invisible to users.
"AI is no longer just transforming technology; it's transforming digital communication itself. In 2026, every conversation will be smarter, faster, and more human. The brands that embrace this shift will turn it into a powerful growth engine," Daniel Morris concluded.
