Identity in 2026: Turning Guest Visibility into Performance

Travel marketers didn’t suddenly forget how to build good programs.The environment changed under them. Third-party cookies, once treated as a universal connector, no longer behave like dependable infrastructure. Browser and OS-level changes have made them fragile at best, irrelevant at worst.

At the same time, travelers now move fluidly between channels and devices: they start inspiration on a mobile device, compare options on a laptop, price-shop on metasearch and OTAs, then book via your app or website — or abandon entirely. The same traveler appears as a trail of disconnected “guests” scattered across your analytics, ESP, CRM, and ad platforms. Layer on top of that a much stricter privacy and consent landscape. What used to be shrugged off as “tracking” now comes with real reputational and regulatory risk, especially for multinational brands operating across strict data regimes.

So you’re forced to choose:

• Keep doing what’s easy and slowly lose signal to walled gardens, OTAs, and privacy changes, or

• Rethink how you recognize and engage travelers altogether.

Your ESP, CRM, and marketing cloud have not become obsolete.

Salesforce Marketing Cloud, Braze, and other orchestration platforms are still excellent at what they were designed to do: orchestrate campaigns, journeys, and reporting for people they know — members, logged-in users, and opted-in subscribers. But they were never built to solve identity at scale across anonymous research sessions, booking engines, and mobile apps or make real-time decisions off partial behavioral data like route searches, property views, or fare checks

When that foundational identity layer is thin, even the most elaborate pre-arrival journeys, abandoned booking nurtures, and loyalty plays are running on a tiny slice of your true audience. Marketers overwhelmingly see identity resolution as a key driver of growth, efficiency, and customer satisfaction — but fewer than a quarter feel confident their programs have the depth, accuracy, persistence, and scale required for modern, multi-device journeys.

Nearly 70% say incomplete identity is what stops them from scaling behavioral email, SMS, and triggered programs in a meaningful way. The conclusion is uncomfortable but helpful:

For years, identity conversations revolved around match rates. Could a partner recognize 20% of your traffic? 30%? 40%? The metric mattered, but the conversation was narrow. In 2026, the lens is wider — especially in travel and hospitality, where every incremental point of conversion on high-intent, direct traffic carries outsized impact on revenue and profitability. The question is no longer just, “How many visitors can you identify?” It’s, “What can your marketing system intelligently do once it recognizes them?”

At Wunderkind, we describe the relationship this way: identity is the eyes; AI decisioning is the brain.

Wunderkind’s own identity network now recognizes over 9 billion consumer devices and 1 billion consumer profiles, built on first-party and observed behavioral data rather than rented third-party lists. That scale isn’t a vanity statistic. It is what makes it possible to turn anonymous sessions — like a traveler comparing dates and room types or a guest searching for flights and ancillaries — into reachable, permissioned profiles that your ESP, SMS provider, and ad platforms can act on confidently. When you put a high-fidelity identity graph beneath an agentic AI decisioning engine, you move from static campaigns to something closer to a responsive nervous system for your guest lifecycle. Journeys are no longer brittle flows that assume a linear path from “search” to “book” to “stay” to “return.”

They become dynamic systems that adapt to what individual travelers are actually doing, in the moment — whether they are:

• Price-checking the same route for the third time
• Bouncing between your brand site and OTAs
• Browsing higher-value room categories without booking
• Looking like a strong candidate for loyalty acquisition or upsell

For advanced travel and hospitality marketers, the most compelling thing about identity in 2026 is not a brand-new channel. It’s the way existing channels behave once they are no longer operating in the dark.

Email and SMS: From Lists to Guest Systems

Most brands still treat email and SMS performance as a function of creative quality and cadence. Those things matter. But for many teams, the bigger constraint is simply who is eligible to receive those messages in the first place. Without an independent identity layer, your ESP will typically recognize only a minority of your daily traffic — often somewhere around 30% of visitors.

Everyone else can:

• Research destinations, properties, or routes
• Build and revise itineraries
• Add rooms, seats, and ancillaries to cart
• Leave without ever entering a single flow

When you add a dedicated identity graph beneath that ESP, the calculus changes. For travel and hospitality, behavioral email stops being a “nice-to-have” retention channel and becomes one of the most efficient performance channels in your stack, routinely driving a double-digit share of total digital revenue. Triggers like:

…begin to fire for far more people, because you’re no longer limited to the small portion who happened to log in or click from a previous campaign.

The same shift happens in text. SMS and MMS evolve from blunt, high-pressure broadcast tools into an urgency and service layer that is tightly coordinated with email and onsite:

• Pre-arrival reminders and check-in guidance
• Last-minute upgrade or upsell opportunities that respect guest intent
• Time-sensitive alerts about disruptions or changes
• Loyalty nudges when a guest is close to the next tier or benefit

Messages are reserved for moments that genuinely warrant a tap on the shoulder: Low inventory on a highly viewed date, an expiring promotion for a high-value basket, a high-propensity guest who is clearly on the fence. Across brands that have paired their ESP with a neutral identity and AI layer, we’ve seen:

• 3–6x more identified visitors
• 15–30% lifts in conversion rates
• Measurable revenue increases from triggered programs in the 30–150% range

Not by inventing new channels, but by letting existing ones reach the audience they were designed for.

Onsite & In-App Experience: Capture as a Strategy

Identity also changes how you think about your website, app, and booking engine. Many travel marketers still treat onsite capture as a disconnected tactic: deploy a popup, offer a discount or loyalty points, hope the list grows. In an identity-first world, onsite experience and capture become part of a larger guest system. When more visitors are recognized in real time, you can adapt experiences based on whether someone is:

• A known loyalty member or past guest
• A high-intent anonymous traveler still in the research phase
• A repeat visitor who has been price-checking or date-shopping for days

Instead of treating every new visitor as a stranger, you can:

• Reduce friction for returning guests, even if they haven’t logged in during the current session (e.g., remembering preferences, pre-filling details where appropriate)
• Design capture units that favor quality, consented data — loyalty membership, opt-ins, and rich context — over raw volume
• Use behavioral and contextual signals to decide when to interrupt with an offer (e.g., a relevant member rate) and when to simply tailor the page or itinerary view

The result is a site and app that behave less like static storefronts and more like high-intent, identity-rich environments where every visit moves the relationship forward, even if the traveler doesn’t convert immediately.

Paid Media and Meta: Paying Once for Each Conversion

The identity story in paid media is as much about efficiency as it is about reach. Rising CPMs and competitive metasearch auctions mean you can no longer afford to pay for impressions that your owned channels could have converted more cheaply and more contextually. When identity connects your owned-channel programs to platforms like Meta, several things become possible:

• You can automatically suppress audiences who are already currently in high-performing email or SMS flows, letting those channels convert first before you invest in paid impressions.
• You can build lookalike and prospecting audiences not from generic pixel events, but from rich, identity-resolved profiles that reflect real traveler behaviors and value (e.g., repeat direct bookers, high ADR guests, or long-stay patterns).

Early adopters of identity-powered Meta campaigns are seeing double-digit reductions in cost per purchase once they stop bidding against their own triggered email and text for the same conversions. Media turns from a blunt instrument into an extension of the same intelligence that powers your owned channels.

ESPs and Marketing Clouds: Intelligence Without Replatforming

One of the more important lessons of the last few years is that you do not need to rip out your ESP or marketing cloud to modernize your travel marketing. You need to complement it. Klaviyo, Salesforce Marketing Cloud, Braze, and other orchestration platforms remain excellent at managing flows, campaigns, and reporting once a user is known. What they lack, by design, is the ability to operate as:

• Independent, large-scale identity networks
• Real-time decision engines that can arbitrate across channels based on guest behavior and business rules

When you add an external identity and AI layer alongside those platforms, they suddenly have more to work with:

• They can see a larger share of your audience, including high-intent anonymous traffic
• They receive richer behavioral signals from your site, app, and booking flows
• They can support higher rungs on the triggered messaging maturity curve, where identity and AI together choose timing, channel, and content — not just pre-set rules keyed to a narrow set of events

You preserve team workflows and reporting structures. What changes is what the system can see — and what it can act on.

Across the 2024 Identity Playbook, the 2026 Tech Stack Guide, and our newest performance marketing research, a clear pattern has emerged. Orchestration still matters. ESPs and marketing clouds are not going anywhere. But orchestration alone is no longer enough. The brands pulling ahead are the ones that treat:

• Identity as the foundation
• AI decisioning as the orchestration engine on top

Put simply:

• Orchestration determines how you message.
• Identity determines who you can message.
• AI decisioning determines what you should do next — and whether you should act at all.

In that world, channels become interchangeable parts. Email, SMS, onsite, in-app, and media are no longer separate teams waging attribution wars. They are simply different surfaces through which the same identity and intelligence can express itself to your guests. For advanced travel and hospitality marketers, the critical question in 2026 is not whether identity matters.That debate is over.

The real questions are:

• How quickly can you treat identity as the backbone of your performance strategy?
• How long are you willing to let anonymous, high-intent travelers walk away unseen — only to reappear on OTAs, metasearch, and competitor sites?
