Why teams connect MotherDuck and SendGrid

Get the data locked inside SendGrid into MotherDuck 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 Email Activity, Contacts, List, Segments from SendGrid into tables in MotherDuck continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in MotherDuck can also be written back into fields in SendGrid where the tool can use them.

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
  • Land CRM and operational database records in MotherDuck so a small team gets warehouse-style analytics without cluster management
  • Sync modeled MotherDuck tables outward to operational tools for activation

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 MotherDuck sync back onto records in SendGrid, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in MotherDuck preserves a queryable record even as data ages out of SendGrid or gets changed inside it.

What you can sync between MotherDuck 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.

How the MotherDuck and SendGrid connectors work

MotherDuck

Integration surface
SQL through DuckDB clients and drivers using a MotherDuck (md:) connection
Authentication
Access token created in MotherDuck (Settings > General > Create Token), pasted into Stacksync; database name and schema configurable if not using defaults
Change detection
Polling; no log-based CDC or webhook surface is exposed
Capabilities
read · write
Rate limits
Subject to the platform's compute and concurrency limits rather than per-request API rate limits
MotherDuck setup guide

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
