The Smart Duo

Track, identify, contextualize, and attribute your audience members' individual omnichannel journeys from first click to conversion and beyond.

What is it?

The Smart Duo consists of the Smart Link, a universal, ready-to-embed individualized, deferred deep link that can be utilized in owned, earned, and paid media marketing and the one-line SDK, a proprietary one-line code that can be embedded across your digital properties.

Where can the Smart Link be used?

The Smart Link can be embedded in a variety of touch points to enhance your engagement efforts.

What sets the Smart Duo apart?

Effective across channels, devices, and browser types, the Smart Link not only takes up minimal characters but is individually generated for every member of your audience.

Built to deliver optimal efficiency, the one-line SDK utilizes device fingerprinting, instead of cookies, to accurately identify every audience member, regardless of the touchpoint from which they arrived. It also facilitates direct in-app content injection to minimize reliance on IT.

Edge-enabled. Built for Future CX

The Smart Duo, like the RESUL platform itself, is powered by next-generation edge, serverless technology. 

What does it entail for marketers? Powered by next-gen edge and serverless technology, the Smart Duo can accommodate digital communications and customer engagement at unprecedented scale and speed. 

The platform’s foundational technology, supported by the WebAssembly framework (WASM), significantly reduces the delays involved in the delivery of relevant, contextual responses when individuals interact with the brand’s touchpoints. It can achieve, in ideal circumstances, a 2000-time boost in the speed of response, further minimizing frictions and lags in omnichannel CX.
