Why teams connect Postgres Heroku and SendGrid

Mirror SendGrid's data into Postgres Heroku 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 Postgres Heroku.

Stacksync mirrors Categories, Senders, Single Sends, Unsubscribe Groups from SendGrid into Sequences, Follower Databases, Tables, Views in Postgres Heroku 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

  • Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting
  • Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
  • Sync Heroku Postgres into a warehouse for reporting without running ETL dynos
  • Keep several Heroku app databases aligned with one system of record

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 SendGrid with a query

Records from SendGrid are ordinary rows in Postgres Heroku; 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 Postgres Heroku and Stacksync propagates the change into SendGrid, replacing custom integration code.

What you can sync between Postgres Heroku and SendGrid

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.

Postgres Heroku objects SendGrid objects
Views Read-side projections exposed to outbound syncs. Email Activity Synced with incremental and full sync per the Stacksync docs.
Materialized Views Precomputed result sets synced outward on refresh. Contacts Marketing recipients upserted from CRM or database records, including custom field values.
Schemas Namespaces that scope which tables a sync reads and writes. List Synced with incremental and full sync per the Stacksync docs.
Primary and Unique Keys Match keys for idempotent upserts from connected systems. Segments Query-based contact groups whose membership SendGrid computes from contact fields.
JSONB Columns Semi-structured payloads for nested SaaS objects and metadata. Categories Synced with incremental and full sync per the Stacksync docs.
Sequences Generate surrogate keys for rows created by inbound syncs. Senders Synced with incremental and full sync per the Stacksync docs.

At scale

Event queues

Handle millions of events per minute without losing a single Postgres Heroku or SendGrid record.

Observability

Monitoring

Track your Postgres Heroku ⇄ SendGrid sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Postgres Heroku and SendGrid.

How the Postgres Heroku and SendGrid connectors work

Postgres Heroku

Integration surface
SQL wire protocol (standard PostgreSQL)
Authentication
Database credentials from the Heroku DATABASE_URL config var; SSL required
Change detection
Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings
Capabilities
read · write
Rate limits
No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan

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
