How to Boost Engagement & Revenue with Full-Journey Automated A/B Testing

A well-structured user engagement strategy powered by marketing automation can give your app a 4.5x increase in qualified leads. At the heart of this strategy is omnichannel 1:1 communication (email, push, in-app notifications) driven by event-triggered messages. It enables your brand to unlock recurring revenue from its value proposition when it matters most.

For a health and fitness app, automated messaging is a reliable prospect-engaging solution, converting casual workout fans into paying subscribers and turning them into lifelong product advocates. But it's a long way to go. In fact, only 3.7% of users remain active 30 days after installing a typical fitness app. This is where automated messaging supported by continuous A/B testing across multi-step user journeys becomes a motivating (and revenue-generating) driver.

Large-Scale Communication Made Easy

Instead of fine-tuning email subjects or push notifications one by one, you can orchestrate personalized user journeys across every touchpoint for maximum conversion impact. Reteno's “One from many” messaging block works best for this specific task. It tries different messages and picks the winner based on real-time user engagement – directly within your workflows.

Here’s how it works:

• Place a “One from many” block element at any point in your campaign workflow and upload multiple message variations.
• The system starts by randomly splitting traffic across all message variants to gather performance data (e.g., click-through rate).
• In real time, Reteno’s algorithm dynamically prioritizes the better-performing nudges.
• Each campaign step “evolves” through continuous A/B testing, optimizing communications to drive consistent user engagement throughout the message flow.

A unique feature is that you don't have to create countless branches or clone entire flows. “One from many” handles it all within a single node, automating both the A/B testing process and test result implementation on the fly.

This continuous optimization is especially powerful for high-churn scenarios where user motivation gradually fades, namely Abandoned Subscription flows and Regular Reminder campaigns. In an upcoming blog post, we’ll explore how “One from many” helps reshape these two campaign types across the customer journey.

Taming Complex Multi-Step A/B Testing with Automation

Adopting deep-learning algorithms (aka generative AI) can bring your business a 6-10% revenue increase. Reteno’s smart messaging block, based on a continuous “test-iterate-optimize pattern,” is one of those conversion boosters.

Without “One from many,” testing multiple message versions across a multi-step communication flow quickly becomes hardly manageable. Say, if you want to test 3 message variations at each of 3 campaign steps, you're looking at:

• 3 x 3 x 3 = 27 possible message sequences

Trying to manually test all 27 sequences would require duplicating flows, managing separate user segments, and running tons of manual A/B tests. As a result, the task gets too complex, time-consuming, and error-prone.

With “One from many,” you get the job done right. You build 1 flow with 1 message sequence. At each campaign step, you place the block, and Reteno handles the rest.

This A/B testing algorithm turns a rigid, hard-to-manage experimental matrix into a seamless, auto-optimized ecosystem. It runs on autopilot, giving you detailed insights into message performance.

The traditional method (left) involves A/B testing each variation in isolation. “One from many” (right) continuously tests and refines messages throughout the journey, ultimately identifying and delivering the best-performing nudge based on real engagement metrics. The result: more conversions without guesswork and duplication.

Why It’s a Must for Segmented and Personalized Campaigns

When running segmented campaigns, you almost always have multiple content versions tailored to specific audience groups. Rather than testing and managing them all manually, simply use “One from many” blocks within flows designed for different segments. Each block automatically tests and fine-tunes the messages within that segment.

For highly personalized journeys, “One from many” ensures that even when you test multiple nudges, the user experience remains consistent and seamless for each prospect/subscriber. Rather than disrupting the campaign logic, let the algorithm dynamically build the path to conversion: step by step, trigger by trigger, action by action.

Final Thoughts

Using non-stop A/B testing, a workout app increased conversions of its regular reminder campaign by 29%. Reteno’s “One from many” solution made it happen. This AI-powered messaging block shifts the paradigm of how marketers approach A/B testing and optimizing user communications. By automating the complex process of testing multiple message variations across entire campaigns, Reteno ensures that every interaction ends with a desired action (e.g., subscription, upgrade to a premium plan). Preventing subscribers from leaving at every step of their experience with the app is directly tied to recurring revenue, which is vital for your H&F product.

A user journey is a living process that can always be improved. With “One from many,” your path to higher engagement, better retention, and increased revenue is clearer than ever.
