Key Features

Its robust identity engine allows businesses to unify customer data across any number of web and mobile touchpoints, building a single, persistent user profile.

Identity resolution is a key strength of the platform, built to handle complex customer journeys. As users move across web, mobile apps, and other sources, the system resolves their distinct identities into one persistent "profile." By mapping these various IDs to a single master record, the platform maintains a continuous history of customer interactions. This is essential for providing a personalized, omnichannel experience, as it ensures that the business can treat every individual user as a coherent, recognized entity regardless of how they choose to interact with the service.

The CRM data integration enables businesses to import and unify offline conversion events, allowing them to trigger automated, personalized responses based on real-world interactions.

To support omnichannel strategies, the platform allows businesses to import offline data such as in-store purchases, event registrations, or CRM-based sales activities. Once imported, these offline events are treated as first-class triggers for automated workflows. For example, if a user makes a physical store purchase that is logged in a CRM, the platform can trigger a personalized email series automatically. This ability to integrate offline realities into the digital communication engine is a major driver of engagement and loyalty for businesses with mixed sales models.

The vendor prioritizes privacy by design, providing robust tools for consent management, data deletion, and GDPR/CCPA-compliant data handling.

Privacy and compliance are built into the platform's core architecture. It provides specialized tools for capturing and managing user consent, tracking opt-ins, and handling data subject requests (DSARs), including automated data deletion. It operates as a Data Processor, keeping the business in control of their own customer data. While these tools provide the necessary framework for operating ethically, the business remains responsible for ensuring their tracking implementation and consent banners are configured correctly according to their specific legal jurisdictions.

Raw data export provides robust data extraction options, allowing enterprises to push user-level behavioral data into external data warehouses for deep analysis.

For data-driven enterprises, the platform offers significant data portability. It provides various options for exporting raw user-level data, including automated data pipelines that can push JSON-formatted event data into data warehouses. This allows teams to combine behavioral data from the platform with internal financial or operational datasets. This direct, granular data access is essential for data teams building their own proprietary attribution models or conducting longitudinal studies on user behavior, providing freedom from the constraints of standard platform reporting.

SSO Support

Supported

Secure enterprise access is enabled through native SAML 2.0 Single Sign-On, integrating with major identity management systems.

To meet corporate security requirements, the platform supports SAML 2.0 Single Sign-On (SSO). IT departments can easily integrate the workspace with identity providers like Okta, Azure AD, or OneLogin, ensuring that access is centrally managed and secure. By mandating SSO, organizations can enforce strict password policies and ensure that access is automatically revoked when employees leave, protecting sensitive customer marketing data and providing a simplified, more convenient login experience for team members.

The visual automation builder is a market-leading tool, allowing marketers to design highly complex, data-driven customer journeys via a drag-and-drop interface.

The visual automation builder is the flagship feature, offering unprecedented flexibility for managing complex communication journeys. Marketers can build elaborate, multi-channel workflows (email, SMS, push) that branch based on any data, event, or condition. Because the platform allows for such deep customization of the user journey, it is widely favored by SaaS and mobile app teams that need to create highly tailored, behavioral-triggered onboarding and retention workflows that go far beyond simple, template-based automation.

This audience-building feature provides a highly flexible segmentation engine that allows marketers to build dynamic groups based on any behavioral event, user property, or interaction.

Segmentation is a powerful, real-time feature. The platform allows marketers to build dynamic segments using any criteria, including geolocation, behavioral events, and custom properties. Because segments are dynamic, contacts are added or removed in real-time as they meet (or fail to meet) the segment rules. This ensures that marketing communications remain perfectly relevant, preventing users from receiving messages that no longer apply to their current status or recent interactions, which drastically improves overall engagement.

The platform excels in advanced email marketing, combining professional design capabilities with deep, data-driven personalization and automation triggers.

Email is a deeply integrated channel within the automation workflow. Beyond standard design capabilities, the platform allows for deep personalization, enabling every email to pull in data from the customer profile. The true power lies in the integration with the platform’s event tracking; emails can be triggered automatically based on specific user actions or inactions. The system provides detailed performance analytics, allowing marketers to optimize their strategy based on factual engagement data and revenue-driven outcomes.

This capability provides native SMS marketing capabilities, allowing brands to reach customers through immediate, high-engagement text messages.

SMS is a first-class channel that integrates seamlessly with email and push notifications. It is a highly effective tool for immediate communication—such as time-sensitive reminders, transactional updates, or flash offers. By utilizing the same visual automation builder as email, marketers can construct complex multi-channel sequences where an SMS acts as a strategic "nudge" in a larger customer journey, significantly increasing the probability of a conversion.

The platform provides advanced liquid-based dynamic content, allowing marketers to tailor messages based on complex user data and behavioral logic.

Personalization is exceptionally deep and technical, utilizing a robust template language ("Liquid"). This allows marketers to insert dynamic logic into emails or site messages: e.g., "if user has purchased X and is in region Y, show discount Z." This level of data-driven tailoring makes communications feel incredibly relevant to the individual user. While it offers more depth than standard drag-and-drop editors, it gives marketing teams the power to create highly sophisticated, tailored customer experiences that drive higher loyalty and conversion rates.

The feature offers comprehensive campaign analytics, allowing teams to track multi-channel performance and map marketing efforts to downstream business results.

Campaign reporting provides a transparent view of performance. It offers metrics not just for the email or SMS campaign itself, but for the entire journey performance. Analysts can see how campaigns impact downstream user behavior and conversion goals. The platform makes it easy to compare the effectiveness of different messaging strategies, allowing teams to continuously refine their communication and maximize the ROI of their overall marketing strategy.
