Why teams connect SendGrid and Supabase
Mirror SendGrid's data into Supabase 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 Supabase.
Stacksync mirrors Single Sends, Unsubscribe Groups, Email Activity, Contacts from SendGrid into Schemas, auth.users, Row Level Security Policies, JSONB Columns in Supabase 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
- Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record
- Sync application tables in Supabase with the CRM two-way so new signups appear as contacts and sales edits flow back to the app
Automate SendGrid from your codebase
Write to the synced tables in Supabase 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 Supabase, 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 SendGrid and Supabase
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 | Supabase objects | |
|---|---|---|
| Single Sends One-off marketing campaigns whose stats are read back for reporting. | Storage Object Metadata File metadata rows that can be joined to synced application data. | |
| Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. | Tables Standard Postgres tables; the primary two-way sync target. | |
| Email Activity Synced with incremental and full sync per the Stacksync docs. | Views Read-side projections exposed to outbound syncs. | |
| Contacts Marketing recipients upserted from CRM or database records, including custom field values. | Schemas Namespaces (public and custom) that scope sync access. | |
| List Synced with incremental and full sync per the Stacksync docs. | auth.users Managed authentication users, often mirrored into CRM or support systems. | |
| Segments Query-based contact groups whose membership SendGrid computes from contact fields. | Row Level Security Policies Row-level access rules that govern what the REST layer exposes. |

How the SendGrid and Supabase 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
Supabase
- Integration surface
- Direct PostgreSQL wire protocol connection, plus an auto-generated REST API (PostgREST)
- Authentication
- Database credentials (connection string) for SQL access; API keys (anon / service role) for the REST layer
- Change detection
- Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime; database webhooks can also fire on row changes
- Capabilities
- read · write · CDC · webhooks
- Rate limits
- SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits

FAQ
SendGrid and Supabase integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between SendGrid and Supabase: authenticate both systems, choose the objects to sync (such as SendGrid's Single Sends and Unsubscribe Groups), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for SendGrid and Supabase: Automate SendGrid from your codebase; React to changes as they happen; One integration pattern for the whole stack. Write to the synced tables in Supabase and Stacksync propagates the change into SendGrid, replacing custom integration code.
-
SendGrid: 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"). Supabase: Direct PostgreSQL wire protocol connection, plus an auto-generated REST API (PostgREST). Authentication: Database credentials (connection string) for SQL access; API keys (anon / service role) for the REST layer. Stacksync manages authentication, retries, and rate limits on both sides.
-
SendGrid: Suppression lists (bounces, blocks, invalid emails, spam reports, unsubscribe groups) are separate resources from the contact database and must be read explicitly. Supabase: Every Supabase project is a full PostgreSQL database, so standard Postgres drivers, SQL tooling, and log-based CDC apply directly. Stacksync's field mapping accounts for these differences between SendGrid and Supabase without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means SendGrid and Supabase records are not retained after a sync operation.
