Why teams connect ClickHouse and SendGrid
Get the data locked inside SendGrid into ClickHouse as live tables, and send results back where SendGrid can use them, without writing a pipeline.
Whatever SendGrid is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.
Stacksync syncs Categories, Senders, Single Sends, Unsubscribe Groups from SendGrid into tables in ClickHouse continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in ClickHouse can also be written back into fields in SendGrid where the tool can use them.
Common use cases
- Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
- Write bounces, spam reports, and unsubscribes back to the CRM to keep email opt-in status accurate everywhere
- Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
- Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
Analytics on SendGrid's data
Records and events from SendGrid land in ClickHouse as queryable tables, current within seconds and ready to join with the rest of the warehouse.
Cross-tool reporting
Combine SendGrid's data with data from every other synced system to answer questions no single tool can.
Where SendGrid accepts updates: operational write-back
Segments, scores, or reference values computed in ClickHouse sync back onto records in SendGrid, putting analysis where the work happens.
What you can sync between ClickHouse 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.
| ClickHouse objects | SendGrid objects | |
|---|---|---|
| Distributed tables Query-routing tables over cluster shards in self-managed deployments. | Single Sends One-off marketing campaigns whose stats are read back for reporting. | |
| Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. | Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. | |
| Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. | Email Activity Synced with incremental and full sync per the Stacksync docs. | |
| Databases Namespaces that group tables and scope permissions for sync users. | Contacts Marketing recipients upserted from CRM or database records, including custom field values. | |
| Views Saved queries used as curated, read-only sync sources. | List Synced with incremental and full sync per the Stacksync docs. | |
| Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. | Segments Query-based contact groups whose membership SendGrid computes from contact fields. |

How the ClickHouse and SendGrid connectors work
ClickHouse
- Integration surface
- Native TCP protocol and HTTP interface; standard SQL dialect, with MySQL and PostgreSQL wire compatibility available
- Authentication
- Database credentials (username/password); ClickHouse Cloud issues per-service credentials over TLS
- Change detection
- No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source
- Capabilities
- read · write
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

FAQ
ClickHouse and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between ClickHouse and SendGrid: authenticate both systems, choose the objects to sync (such as ClickHouse's Distributed tables and Dictionaries), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes — Stacksync ships production-grade connectors for both ClickHouse and SendGrid. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on ClickHouse: No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source. On SendGrid: 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. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the SendGrid side: Categories, Senders, Single Sends, Unsubscribe Groups, plus custom fields where SendGrid exposes them. On the ClickHouse side: Dictionaries, Tables (MergeTree family), Databases, Views. Stacksync auto-detects both schemas and converts types between the two systems.
-
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 ClickHouse and SendGrid: Analytics on SendGrid's data; Cross-tool reporting; Where SendGrid accepts updates: operational write-back. Records and events from SendGrid land in ClickHouse as queryable tables, current within seconds and ready to join with the rest of the warehouse.
