Amplitude & Braze Integration: Cohort-Based Messaging

Overview

Amplitude and Braze are both powerful platforms, but they serve different purposes. Amplitude excels at understanding user behavior through analytics and cohort segmentation, while Braze specializes in orchestrating personalized customer communications across email, push, in-app, and SMS channels. The native integration between them bridges this gap: you build audience segments in Amplitude based on behavioral data, then activate those cohorts in Braze to deliver targeted messages to the right users at the right time.

This integration is particularly valuable for teams that rely on behavioral analytics to inform marketing decisions. Instead of manually exporting lists or building duplicate segments in Braze, you can leverage Amplitude’s sophisticated cohort logic and push those audiences directly into your messaging platform.

How the Integration Works

• Cohort Creation in Amplitude: Define audience segments in Amplitude based on user actions, properties, and behavioral patterns (e.g., “users who viewed product X but didn’t purchase in the last 30 days”).
• Sync to Braze: Once a cohort is created, you can configure it to sync to Braze. Amplitude automatically pushes user identifiers and cohort membership data to Braze’s platform.
• Audience Activation: In Braze, the synced cohort appears as an available audience segment. You can then select it as the target for email campaigns, push notifications, in-app messages, or SMS flows.
• Real-Time Updates: As users enter or exit the cohort in Amplitude based on their ongoing behavior, Braze updates audience membership, ensuring your campaigns always reach the correct users.
• User Identity Mapping: The integration uses consistent user identifiers (typically email or user ID) to ensure accurate matching between the two platforms.

Key Features & Capabilities

• Behavioral Segmentation at Scale: Create complex audience segments in Amplitude using multi-step user journeys, event sequences, and property filters, then instantly activate them in Braze without manual data entry.
• Dynamic Audience Updates: Cohorts sync continuously, so users automatically enter or exit Braze audiences as their behavior changes in Amplitude, keeping your campaigns fresh and relevant.
• Reduced Campaign Setup Time: Eliminate the need to build duplicate segments in Braze. Define your audience once in Amplitude and reuse it across multiple Braze campaigns.
• Cross-Channel Messaging: Use Amplitude cohorts to target users across Braze’s full communication stack—email, SMS, push notifications, and in-app messages—from a single audience definition.
• Improved Campaign Performance: By leveraging Amplitude’s behavioral insights, you can send more relevant messages to highly qualified audience segments, typically improving open rates, click-through rates, and conversions.
• Audit Trail & Transparency: Track which cohorts are active in Braze and understand the logic behind each segment, making it easier to troubleshoot campaign performance or adjust targeting criteria.

Setup Difficulty: Medium

Expect 15–30 minutes to set up this integration. You’ll need to:

• Authenticate Braze within Amplitude (requires Braze API credentials).
• Configure user identity mapping to ensure Amplitude and Braze recognize the same users.
• Create or select an existing cohort in Amplitude and enable syncing to Braze.
• Verify the cohort appears in Braze and test with a small audience before launching campaigns.

No custom code is required, but you’ll need admin access to both platforms and basic familiarity with how each tool structures audiences and API credentials. If your organization uses a single sign-on (SSO) system or has complex identity resolution needs, setup may take slightly longer.

Common Use Cases

Re-engagement Campaigns: Identify users in Amplitude who haven’t logged in for 60+ days, then automatically send them a personalized re-engagement email in Braze.

Product Launch Messaging: Create a cohort of users who have viewed your product roadmap or beta signup page, then target them with an exclusive launch announcement via push notification and email.

Churn Prevention: Build a cohort of users showing early churn signals (declining session frequency, reduced feature usage), then trigger a win-back campaign in Braze offering support or incentives.

Upsell & Cross-Sell: Segment users by purchase history and product usage in Amplitude, then send targeted Braze campaigns promoting complementary products or premium features.

Alternatives & Workarounds

If the native Amplitude–Braze integration doesn’t fully meet your needs, consider these options:

• Zapier or Make: Use a no-code automation platform to trigger Braze campaigns when Amplitude cohort membership changes. This adds flexibility but introduces latency compared to native syncing.
• Custom API Integration: If you need real-time, bidirectional syncing or custom data transformations, your engineering team can build a direct API connection using Amplitude’s cohort export API and Braze’s audience API.
• CSV Export & Manual Upload: For one-time campaigns or ad-hoc audiences, export a cohort from Amplitude as CSV and upload it to Braze. This is slower but requires no integration setup.
• Segment (CDP): If you use Segment as a central customer data platform, you can ingest Amplitude data into Segment and then route audiences to Braze, giving you additional transformation and governance capabilities.

Integration Limitations & Considerations

While powerful, this integration has a few practical constraints to keep in mind:

Cohort Sync Latency: Updates from Amplitude to Braze typically occur within minutes, but not instantaneously. If you need real-time audience changes, verify the current sync frequency with your account team.

Identity Resolution: The integration relies on consistent user IDs or email addresses between Amplitude and Braze. If your user identity model differs between platforms, you may need to map IDs manually or use a third-party identity resolution tool.

Cohort Size Limits: Some Braze plans may have limits on the number of active audiences or the size of audiences you can import. Check your Braze contract for details.

Unidirectional Sync: Amplitude cohorts push to Braze, but Braze campaign performance data doesn’t automatically flow back to Amplitude. You’ll need to use Amplitude’s Braze integration for event tracking to close this loop.

Frequently Asked Questions

Can I use Amplitude cohorts in Braze without any coding?

Yes. The native integration is designed for non-technical users. You create a cohort in Amplitude’s UI, enable syncing to Braze, and then select that cohort as an audience in Braze’s campaign builder. No API calls or custom code are required for basic setup.

How often do Amplitude cohorts update in Braze?

Cohort membership updates typically sync within minutes of a user’s behavior change in Amplitude. However, the exact frequency depends on your Amplitude plan and Braze configuration. Contact your account manager for specific sync intervals.

What user identifiers does the integration support?

The integration uses email addresses and user IDs to match users between Amplitude and Braze. Ensure both platforms are configured to recognize the same primary identifier for each user to avoid mismatches.

Can I sync multiple Amplitude cohorts to Braze at the same time?

Yes. You can enable syncing for as many cohorts as you need. Each cohort will appear as a separate audience in Braze, allowing you to run multiple targeted campaigns simultaneously.
