Why teams connect Neo4j and Resend

Mirror Resend's data into Neo4j so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Resend through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Neo4j.

Stacksync mirrors API keys, Emails, Contacts, Audiences from Resend into Labels, Indexes & Constraints, Databases, Users & Roles in Neo4j and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Resend, so the tool and the database never disagree.

Common use cases

  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Mirror CRM accounts and contacts into a graph to model buying-group and referral relationships.
  • Sync product catalog and order history into Neo4j to power recommendation queries.

Automate Resend from your codebase

Write to the synced tables in Neo4j and Stacksync propagates the change into Resend, replacing custom integration code.

React to changes as they happen

Updates in Resend arrive as row changes in Neo4j, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

What you can sync between Neo4j 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.

Neo4j objects Resend objects
Properties Key-value attributes on both nodes and relationships, mapped from source fields. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
Labels Node type markers used to map source tables or objects onto the graph. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Indexes & Constraints Uniqueness constraints and indexes that make MERGE-based upserts reliable and fast. Broadcasts One-to-many campaign sends addressed to an audience.
Databases Named databases in a single instance that scope multi-tenant or multi-domain syncs. Domains Verified sending domains with DNS and DKIM status.
Users & Roles Security principals controlling what an integration credential can query or modify. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Nodes Entity records (customers, products, accounts) written from source systems as labeled nodes. API keys Scoped credentials managed per environment for send and read access.
