Why teams connect SendGrid and VoltDB

Mirror SendGrid's data into VoltDB 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 SendGrid 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 VoltDB.

Stacksync mirrors Senders, Single Sends, Unsubscribe Groups, Email Activity from SendGrid into Export Targets and Topics, Partitioned Tables, Replicated Tables, Stored Procedures in VoltDB 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 SendGrid, so the tool and the database never disagree.

Common use cases

  • Reconcile transactional email activity with support tickets so agents see what a customer was sent
  • Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
  • Push aggregates from VoltDB materialized views into dashboards or operational tools.
  • Sync customer or account reference data from a CRM into VoltDB replicated tables for in-transaction lookups such as fraud or policy checks.

Read SendGrid with a query

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

Automate SendGrid from your codebase

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

React to changes as they happen

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

What you can sync between SendGrid and VoltDB

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.

SendGrid objects VoltDB objects
Categories Synced with incremental and full sync per the Stacksync docs. Stored Procedures Precompiled transactional units that serve as the primary write interface.
Senders Synced with incremental and full sync per the Stacksync docs. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources.
Single Sends One-off marketing campaigns whose stats are read back for reporting. Streams Insert-only constructs that feed the export subsystem with committed rows.
Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks.
Email Activity Synced with incremental and full sync per the Stacksync docs. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target.
Contacts Marketing recipients upserted from CRM or database records, including custom field values. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data.

How the SendGrid and VoltDB connectors work

SendGrid

Integration surface
REST API (v3)
Authentication
API key (create in SendGrid Settings > API Keys with Custom Access / Full Access for the objects to sync; key begins with "SG")
Change detection
Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling
Capabilities
read · write · webhooks
Rate limits
Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes
SendGrid setup guide

VoltDB

Integration surface
SQL over JDBC plus native client libraries and an HTTP/JSON interface
Authentication
Database credentials
Change detection
Export streams and topics push committed changes to configured targets; otherwise polling
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by partition count and cluster sizing.
How it works

How to connect SendGrid to VoltDB — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
