Why teams connect MariaDB and Resend

Mirror Resend's data into MariaDB 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 MariaDB.

Stacksync mirrors Domains, Email events, API keys, Emails from Resend into Primary and Unique Keys, System-Versioned Tables, JSON Columns, Stored Procedures in MariaDB 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.
  • Two-way sync between a MariaDB application database and a CRM so both systems hold the same customer records
  • Replicate ERP or billing master data into MariaDB databases that power customer-facing applications

React to changes as they happen

Updates in Resend arrive as row changes in MariaDB, 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.

Read Resend with a query

Records from Resend are ordinary rows in MariaDB; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between MariaDB 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.

MariaDB objects Resend objects
Tables The primary sync target; rows map to records in connected systems. Domains Verified sending domains with DNS and DKIM status.
Views Read-side projections used as outbound sync sources. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Columns Field-level mapping targets with engine-typed values. API keys Scoped credentials managed per environment for send and read access.
Primary and Unique Keys Match keys for idempotent upserts. Emails Sent messages retrievable by ID with current delivery status.
System-Versioned Tables Temporal tables that retain row history natively, useful for auditing synced changes. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
JSON Columns Semi-structured payloads validated with JSON functions. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
