Why teams connect Dynamo DB and Resend

Mirror Resend's data into Dynamo DB 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 Dynamo DB.

Stacksync mirrors Emails, Contacts, Audiences, Broadcasts from Resend into Items, Attributes, Partition and Sort Keys, Global Secondary Indexes in Dynamo DB 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

  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Keep suppression and unsubscribe state synced between Resend and other marketing tools to stay compliant.
  • Consolidate multi-region Global Tables data into a single reporting store.
  • Replace ad-hoc export scripts with continuous sync driven by DynamoDB Streams.

Read Resend with a query

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

Automate Resend from your codebase

Write to the synced tables in Dynamo DB 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 Dynamo DB, so triggers, jobs, and services can respond in near real time.

What you can sync between Dynamo DB 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.

Dynamo DB objects Resend objects
Tables The top-level containers a sync targets; each table is addressed independently. Emails Sent messages retrievable by ID with current delivery status.
Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Partition and Sort Keys The primary key pair used as the match key for bi-directional sync. Broadcasts One-to-many campaign sends addressed to an audience.
Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes. Domains Verified sending domains with DNS and DKIM status.
DynamoDB Streams Ordered item-level change records consumed for incremental sync. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
