Why teams connect Braze and Resend

Stop re-entering the same information in Braze and Resend: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Segments, Campaigns, Canvases, Subscription Groups in Braze with Emails, Contacts, Audiences, Broadcasts in Resend in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • Push product usage events from a database or warehouse into Braze to trigger onboarding and retention journeys.
  • Keep subscription and consent states consistent between Braze subscription groups and the CRM or CDP of record.
  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.

Where Resend is where the team documents or plans: keep its data fed

Information that originates in Braze stays current in Resend instead of going stale after a one-time paste.

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

What you can sync between Braze and Resend

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Braze objects Resend objects
Purchases Transaction records logged against profiles for revenue-based targeting. Broadcasts One-to-many campaign sends addressed to an audience.
Segments Audience definitions read for membership export and campaign targeting. Domains Verified sending domains with DNS and DKIM status.
Campaigns Message sends whose metadata and analytics are read for reporting. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Canvases Multi-step journeys; entry and performance data is read for lifecycle analysis. API keys Scoped credentials managed per environment for send and read access.
Subscription Groups Channel-level opt-in states synced with consent records in other systems. Emails Sent messages retrievable by ID with current delivery status.
Content Blocks Reusable message content referenced across campaigns. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
