A/B Testing in Braze: How to Optimize Campaign Performance

In the world of digital marketing, every click, every interaction, and every message matters.
However, one of the biggest challenges brands face is accurately measuring which strategy delivers the best results.
That’s exactly where Braze’s A/B Testing (split testing) feature comes into play.

In this article, you’ll learn how A/B testing works within the Braze platform, which metrics to track, and how Omtera’s Braze expertise helps you optimize campaign performance step by step.

What Is Campaign Optimization and Why Does It Matter?

Campaign optimization is a data-driven process that enables brands to continuously improve their digital marketing strategies.
The goal is not just to run a campaign but to analyze every interaction’s performance and achieve higher conversion rates over time.

Today, for marketing teams, this concept has become the key to growth at every stage of the customer lifecycle.
With the right optimization process, brands can:

  • Adjust message content based on real user data,
  • Test channel and timing preferences,
  • Continuously refine audience segmentation,
  • Reduce costs while increasing engagement rates.

For all of this to work effectively, data collection, analysis, and activation must function in harmony.
This is where Braze stands out — not just as a measurement tool but as an AI-powered customer engagement platform that automates campaign optimization.

A/B testing lies at the heart of Braze’s campaign optimization strategy.
Through these experiments, brands can statistically determine which message, channel, and timing truly work.
In the next section, we’ll explore how A/B testing works in Braze and how Omtera adds strategic value to the process.

What Is A/B Testing and Why Is It Important?

A/B testing is the method of comparing two (or more) versions of a message or campaign to determine which one performs better.

For example:

  • You can test two different subject lines in the same email campaign.
  • You can use different CTAs (call-to-action) in your push notifications.
  • You can experiment with different delivery times for your campaigns.

Braze eliminates the manual work by providing an automated, statistically significant, and scalable testing framework.

Why is it important?
Because brands today make decisions based on data, not assumptions.
Braze A/B testing not only boosts your campaign performance but also helps you understand audience behavior and preferences.

How A/B Testing Works in Braze

Braze structures A/B testing in a simple and flexible way:
You can create tests at the Canvas (journey flow) or Campaign (single campaign) level.

1. Create Your Variants

Identify the element you want to test:

  • Message content (e.g., headline, visuals, CTA)
  • Timing (e.g., 9 AM vs. 6 PM)
  • Channel (e.g., email, push, SMS)
  • Target segment (e.g., new users vs. active users)

Add each version as A and B. Braze automatically splits your audience evenly.

2. Select Your Performance Metrics

Define how you’ll measure success:

  • Open Rate
  • Click-Through Rate (CTR)
  • Conversion Rate
  • Engagement Duration
  • In-app Actions

Braze monitors these metrics in real-time and calculates confidence intervals to determine which variant performs better.

3. Automatically Apply the Winner

Once the winning variant is identified, Braze automatically sends that version to the remaining audience.
This makes A/B testing not just about analysis — but an integral part of continuous optimization.

Designing Effective Tests in Braze: Best Practices

A/B testing doesn’t end with creating variants. It requires strategic planning and accurate interpretation.
Here are Omtera’s top recommendations:

1. Define a Clear Hypothesis

Avoid random testing; always test with intent.

Example: “Shorter subject lines will increase open rates by 10%.”

2. Follow the Single-Variable Rule

Change only one element per test.
Testing multiple variables at once makes it impossible to identify which change drove the result.

3. Ensure a Sufficient Sample Size

Braze automatically calculates the minimum audience size for statistical significance. Don’t test below that threshold.

4. Consider Timing

User behavior varies by time of day and day of the week.
Keep your test running for at least 3–7 days for reliable insights.

5. Don’t Draw Conclusions Too Early

Interactions can evolve over time. For example, in email or in-app messages, results from the first 24 hours can be misleading.

Key Metrics to Track in Braze A/B Testing

A/B testing in Braze not only evaluates variant performance but also reveals how effective your overall campaign optimization strategy truly is.
To ensure meaningful results, tracking the right metrics is essential.
Here are the most important performance indicators to monitor:

1. Open Rate

This metric measures how engaging your email or push notification is to users.
It’s ideal for evaluating the effectiveness of subject lines, preview text, and delivery timing.
An increase in open rate often indicates strong targeting and compelling messaging.

2. Click-Through Rate (CTR)

CTR reflects how well your message drives user engagement.
Elements like CTA copy, button design, and layout all directly influence CTR.
The higher this rate, the stronger your content and creative execution are.

3. Conversion Rate

Conversion rate measures the percentage of users completing your desired action (e.g., purchase, form submission, subscription).
Braze tracks this data per campaign, revealing which variant delivers the best commercial outcomes.
Remember: true optimization is measured by conversions, not clicks.

4. Retention Rate

Retention indicates whether users stay engaged with your brand over time.
Analyzing retention alongside A/B test data helps you measure not just short-term impact but also long-term loyalty.
For mobile app campaigns, retention is a key optimization pillar.

5. Unsubscribe Rate

Though often seen as negative, unsubscribe rates are a valuable indicator of customer satisfaction.
Monitoring this in Braze helps you balance frequency, relevance, and tone across channels.
A high unsubscribe rate may point to over-communication or irrelevant content — a sign your strategy needs recalibration.

When viewed together, these metrics prove that A/B testing is not just an experiment but a continuous, data-driven learning process.
With Omtera’s Braze consulting, you can interpret these insights, identify trends, and refine future campaigns for stronger impact.
