CHALLENGE

Scaling communication channels without scaling the team

As a leading SaaS company in Sweden, Rule is built around email marketing and provides a multi-channel digital communication platform for campaigns, marketing automation, and transactional messages. Despite operating with just 35 employees, it manages communications for approximately 4,000 customers across e-commerce, media, and global brands – a scale made possible only by automation and strategic partnerships.

For Rule’s customers, digital communication drives retention, fuels growth, and shapes brand perception. When it works, their customers succeed. When it fails, revenue critical messages miss the right audience, journeys lose coherence across channels, and brands pay the price in churn and lower lifetime value.

Customer expectations were expanding beyond email. People increasingly wanted to hear from brands on the same mobile channels they already use, from SMS to RCS and other messaging apps. Each region had its own preferences:

• RCS emerged as a dominant channel in Western Europe
• SMS remained strong in developing markets with lower internet penetration
• conversational apps spread globally.

For Rule, that growth created a direct competitive threat. Supporting each new channel traditionally meant point-to-point integrations, separate vendor relationships, and regional compliance requirements managed individually.

Every addition multiplied engineering work, vendor coordination, and sender setup. For a small team managing a large base of customers, the cost of keeping pace grew exponentially with each new channel. Falling behind meant losing customers to platforms that could offer more.

Rule faced a clear choice: invest heavily in in-house engineering, or find a partner who had already solved the complexity.

SOLUTION

A trusted partnership rebuilt on global reach, speed, and trust

Rule first worked with Infobip in 2012 for support with SMS. After exploring other vendors, it returned to Infobip in 2022. They needed a partner that could support multiple messaging channels through a single integration layer, instead of forcing their team to manage separate channel-by-channel builds.

Our well-established relationship proved invaluable. The Infobip team checked in regularly, monitored Rule’s campaigns proactively, and demonstrated genuine commitment to their success rather than operating as a transactional vendor.

Rule describes the implementation process with Infobip as fast, seamless and invisible to customers. The team switched from a competing provider in under a month, while maintaining full services for their customers and avoiding any downtime.

The business connected Infobip’s messaging capabilities into its own platform through a thin integration layer. They keep control over personalization, automation, segmentation, and campaign flows, while Infobip handles delivery, sender certification, compliance, and carrier relationships.

When a customer sends a message, Rule traces it by user ID so usage and billing stay accurate, and uses Infobip analytics to track SMS and RCS performance and forecast volumes month to month.

From constraint to competitive advantage

The impact extended directly to Rule’s customers. Its customers use different channels for different moments in the journey. Email remains valuable for richer campaign content, SMS works especially well for urgent reminders and deadline-driven alerts, and RCS adds a more branded, interactive mobile experience.

A customer of Rule running a loyalty platform previously had to segment customers and decide who received SMS versus email – limiting reach and impact. With RCS available through Rule and Infobip, the customer could add a richer mobile experience without losing the immediacy that makes messaging so effective.

But the real innovation was speed. Customers could now test different channels in days, not weeks. Within the Rule platform, they build the message, choose the right channel for the use case, and launch without complex integration work behind the scenes.

They might send SMS one day, RCS the next, email the third, and measure performance in real time. This low-friction experimentation changed behavior – brands saw that SMS was most effective not for broad marketing blasts, but for time-sensitive alerts and reminders like “Your offer expires in 48 hours. Click here.”

Rule’s customers now have access to SMS and RCS through a single interface, all powered by Infobip’s delivery infrastructure.

RESULTS

2x SMS traffic without increasing headcount, and first with RCS in Sweden

Our partnership delivered measurable and immediate impact.

In the first quarter of 2026, Rule doubled SMS traffic without growing its customer base. The growth came from existing customers using SMS more strategically. Simple channel-selection flows inside its platform made it easier to test what worked and scale the channels that delivered results.

As channel selection became frictionless, customers discovered the strategic value of SMS and increased their usage organically. That increase in traffic expanded its SMS revenue without having to hire more staff, because their engineering team had already abstracted away channel management complexity, so they could support it without adding headcount.

Rule was also among the first platforms in Sweden to offer RCS. This gave them a competitive advantage that directly supports customer retention and market positioning as RCS adoption accelerates.

Operationally, Rule’s small team now supports 4,000 customers by focusing on platform logic, customer success, and market expansion rather than building and maintaining channel integrations.

Its relationship with Infobip’s local team reduces operational friction even further, with direct access to experts who understand the business and can respond faster on pricing, volume forecasting, and technical issues.

For end customers, the experience is simple: receive the right message in the right format at the right time, whether an SMS alert, an RCS rich card, or an email newsletter.

Global expansion and what comes next

Rule’s partnership with Infobip allows them to enter new markets confidently. Germany is its biggest strategic focus for 2026, leveraging RCS strength in that market and Infobip’s local expertise to navigate regional channel preferences. Infobip’s sender certification and compliance capabilities have also enabled Rule to serve emerging markets including customers in Africa where local sender setup and deliverability requirements could otherwise slow expansion.

Looking ahead, the business sees communication evolving toward true two-way dialogue: not just message delivery, but customer reviews, peer recommendations, and interactive journeys. Rule’s free platform tier includes a footer link that turns satisfied recipients into new customers – a peer-to-peer growth model powered by excellent communication.
