Why are marketing teams switching?
The rules of customer engagement have changed. Generic blasts and batch-and-blast campaigns are no longer effective in capturing attention or driving meaningful results. Today’s customers demand personalized, real-time interactions that demonstrate a deep understanding of their needs and preferences. In fact, research shows that 71% of consumers expect personalized interactions with brands, and those who receive them are 80% more likely to make a purchase. For marketing leaders seeking to elevate their customer engagement strategy, the question isn’t if they should upgrade their platform, but when. The shift from legacy solutions like Iterable to a future-proof platform like Braze is becoming a strategic imperative for organizations looking to stay ahead of the curve.
Braze just works.
Braze isn’t just a platform; it’s an engine for growth, designed to empower marketing teams in today’s dynamic environment. Its core strengths lie in its intuitive design, future-proof architecture, and robust support for real-time engagement:
- Intuitive User Interface. Marketing teams thrive when they have the right tools. Braze’s intuitive user interface empowers marketers to focus on strategy and creativity, not on navigating complex systems. This translates to increased efficiency, faster campaign execution, and a greater ability to experiment and optimize. When teams can easily access and leverage the platform’s full potential, they’re better equipped to drive impactful results.
- Future-proof architecture. Vendor lock-in presents a significant risk to marketing agility. Braze’s architecture is designed for seamless integration with existing and future technologies. This approach ensures your marketing stack remains adaptable, allowing you to capitalize on new opportunities without costly platform migrations. This flexibility supports long-term scalability and protects technology investments. Braze’s high-performance REST APIs support up to 3,000 requests per three seconds, with batching capabilities for up to 75 events per request, surpassing the limitations of less scalable platforms.
- Support for real-time use cases across all channels. Capturing the ‘moment of truth’ requires immediate action. Braze’s infrastructure handles real-time data streaming from multiple sources, enabling personalized messages at scale, precisely when and where they matter most. This is essential for driving engagement, maximizing conversion rates, and building lasting customer relationships. Braze’s event-driven architecture ensures that messages are triggered instantly based on user actions, such as a completed purchase or an abandoned cart, via the SDK or custom webhook integrations.
Leave behind the limitations of Iterable
Limitations in key areas like advanced segmentation, cross-channel orchestration, and real-time personalization create a significant gap between marketing ambition and execution.

Today’s customers expect personalized experiences, and data shows that this expectation translates directly to revenue: personalized emails drive six times higher transaction rates. Platforms like Iterable, lacking these capabilities, struggle to meet these expectations and capture this potential.
| CHALLENGE | ITERABLE’S LIMITATION | IMPACT ON BUSINESS | BRAZE’S SOLUTION |
|---|---|---|---|
| Limited cross-channel orchestration | Difficulty in creating seamless customer journeys across multiple channels beyond email. | Hinders cohesive customer journeys, limits the effectiveness of multi-channel campaigns, and restricts the ability to engage customers across their preferred touchpoints. | Extensive SDK support (iOS, Android, Web) and channel flexibility (email, SMS, push, in-app, webhooks) for seamless omnichannel engagement. |
| Basic segmentation capabilities | Challenges in creating highly targeted segments based on complex user behavior and attributes. | Restricts targeted messaging, reduces the relevance of marketing efforts, and limits the ability to personalize experiences based on granular customer data. | Advanced segmentation capabilities that allow for highly targeted segments based on complex user behavior and attributes. |
| Real-time personalization limitations | Inability to deliver personalized messages based on immediate user actions and context. | Missed opportunities to engage customers in the moment and deliver highly relevant experiences, resulting in lower conversion rates and reduced customer satisfaction. | Dynamic content with Liquid templating and real-time triggers based on user actions (e.g., completed purchase, abandoned cart) via SDK or custom webhook integrations. |
| Limited analytics and reporting | Limited insights into campaign performance and user behavior for data-driven optimization. | Impedes data-driven decision-making, restricts the ability to optimize campaign performance effectively, and makes it difficult to measure the true impact of marketing efforts. | Real-time dashboards and robust A/B testing capabilities for granular insights into campaign performance and user behavior. |
| Scalability and Performance | Steeper learning curve and less user-friendly experience compared to Braze. | Limits the ability to handle high volumes of data and interactions, hindering growth and potentially impacting platform performance during peak usage. | Braze’s high-performance REST APIs support up to 3,000 requests per three seconds, with batching capabilities for up to 75 events per request. Infrastructure optimized for real-time data processing, even during peak loads. |
| Limited API Rate and Real-Time Events | Real-time event handling may need extra configuration for high-volume scenarios. | Restricts the ability to integrate with other systems, deliver timely, event-triggered messages, and fully leverage real-time data for personalized experiences. Creates bottlenecks and limits the ability to scale marketing efforts. | Braze’s infrastructure is optimized for real-time data processing, ensuring timely, relevant messages even during peak usage. Robust API and webhook capabilities for seamless integrations and real-time event triggering. |
