Wonder Cave, a text messaging technology company, needed to enhance text messaging as a viable marketing channel by adding personalization and real-time analytics capabilities. They partnered with Rebrandly to create a system for generating unique, branded links with custom domains at a massive scale—up to 10 million messages daily.

The partnership resulted in Wonder Cave’s customers seeing a 60% increase in click-through rates, with 97% of all campaigns managed by Wonder Cave now using these tracking features. The collaboration culminated in Rebrandly Relay™, a fully automated messaging solution that drives a flywheel of superior performance and actionable insights for text campaigns.

Overview

Text messaging is one of the most popular forms of communication worldwide, with over two trillion texts sent yearly. Text is strategic and tactical, efficient and effective, boasting a 98% open rate and immense ROI, generating $71 for every dollar spent.

In a world where communication is fragmented and channel proliferation is accelerating, traditional modes of marketing distribution like email, social media, and display ads are losing effectiveness. Brands must make intelligent bets with their marketing budgets or risk losing relevance and revenue for good. Text messaging’s uniquely personal method of 1:1 connection makes it a particularly effective marketing and communication channel. Marketing organizations are increasing their SMS spend by over 20% YoY

To make the case even more potent, the potential reach of SMS, MMS, RCS, and other text services is enormous, so there is an opportunity for exponential performance, assuming the right tools are in place. Wonder Cave, who offers peer-to-peer (P2P) and application-to-peer (A2P) solutions, recognized the opportunity and built its platform to help businesses connect and engage with audiences through various forms of text messaging.

In Rebrandly, Wonder Cave found a perfect partner to expand its 1:1 text messaging infrastructure with a unified goal of supporting the technical needs of organizations seeking audience engagement at scale. 

The challenge: Making text campaigns data-driven and personal at scale

To establish itself as a challenger in the global CPaaS market, Wonder Cave needed to address the inherent friction in text message marketing head-on. Just three years ago, text messaging wasn’t as well-established as other marketing channels, like email or social media—mainly due to the lack of visibility into messaging campaign performance. 

With the rise of data-driven marketing across channels, it was clear that existing messaging tools lacked the necessary embedded functionality to evolve texting into a viable marketing and communications channel. “There was an assumption that granular analytics and insights, or sending custom links per contact, wouldn’t be part of a text solution,” shared Webb Bostic, President of Wonder Cave, when speaking about the industry’s legacy limitations.

The Wonder Cave team sought to enhance their platform with personalization and real-time campaign analytics. After researching enterprise link management solutions recommended by other Stagwell Marketing Cloud companies, they realized Rebrandly’s API was robust and reliable enough to handle the massive volume of messages sent through their platform, which can average up to 10 million daily.
Wonder Cave partnered with Rebrandly to create a system for generating unique, branded links featuring custom domains. These links are generated at a scale that matches their client’s high-volume messaging needs. 

Rebrandly’s technology team collaborated with Wonder Cave on the design and testing of the solution, giving Wonder Cave confidence and peace of mind and a growth-minded partner who shared their vision and dedication to revolutionizing the future of personalized messaging at scale.

“Rebrandly is the best we’ve seen. They create a crazy amount of volume with the highest deliverability and performance – more than a million links in a minute.”

Solution: Scaled text campaigns with unique branded links and real-time analytics 

Rebrandly’s link management expertise enables Wonder Cave to offer its clients link customization and dynamic link tracking, enhancing their campaigns’ effectiveness and clarity. Instead of sending the same generic link to everyone and hoping for the best, users can generate unique, branded short links with real-time tracking and analytics. That advanced functionality improves sender recognition, boosting view-through rate (VTR), conversion rates, and overall campaign performance. 

Those improvements transformed Wonder Cave customers’ thoughts about their content strategy and text initiatives as a strategic growth lever–not just another communication channel. 

After implementing Rebrandly branded links, Wonder Cave users saw a 60% increase in click-through rates.

Dynamic link tracking and real-time audience analytics quickly became a key feature for Wonder Cave’s users. “97% of our campaigns include these features,” explained Matt Rohr, VP of Operations at Wonder Cave. “Our customers have been able to elevate their data, get rapid feedback on performance, and scale campaign optimization with us as a result. The functionality that Rebrandly enables is now the number one ask from our clients.”

Working with Rebrandly to facilitate large-scale link generation and analytics features allowed the Wonder Cave team to turn text messaging into a valuable and viable marketing channel for its customers. The strengthening partnership between the two companies led to more insights into the nature of 1:1 communications at scale and the opportunity to join forces and innovate. together.

Impact: Relay powers 50M daily messages with 60% higher engagement

In December 2024, Rebrandly and Wonder Cave released Rebrandly Relay™ to streamline 1:1 text messaging for the global communications market. Relay is a fully automated messaging solution that combines the futureproof deliverability and automation Wonder Cave is known for with Rebrandly’s real-time analytics and scalable custom domain generation — for a seamless messaging experience that drives exponential engagement. 

Wonder Cave leveraged Relay to help non-profit organizations run fundraising campaigns for Hurricane Helene relief efforts in North Carolina, resulting in a 30% increase in campaign donations. According to Bostic, “every customer has benefited since we launched this integration. Our clients can more easily hone in on engaged audiences, which reduces their overall texting spend and dramatically increases ROI.”

Wonder Cave manages a vast number of messages on behalf of its clients every day, sometimes up to fifty million in a single day. Their customers rely on the deliverability of those messages to be processed with unique, branded, trackable links for each recipient. 

“I’ve long held that speed is one of our biggest differentiators in the market,” says Vinnie Rossi, Wonder Cave CTO. “I don’t think anyone can produce as many messages as fast and reliably as we can. And for that kind of velocity, there’s just no other option. Rebrandly is the best we’ve seen — they can create a crazy amount of volume with the highest deliverability and performance – more than a million links in a minute.”
