Why teams connect Rillet and SendGrid
Connect the financial records in Rillet with the work happening in SendGrid, so both stay current without exports or copy-paste.
Rillet holds the financial truth: who the customers are, what they were billed, what they paid. SendGrid is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.
Stacksync keeps Account, Customer, Vendor, Invoice in Rillet and Senders, Single Sends, Unsubscribe Groups, Email Activity in SendGrid in sync, bi-directionally and in real time. Whatever records SendGrid keeps and whatever events it produces, the overlap with Rillet is mapped field by field, and a change on either side shows up on the other within seconds.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.
Common use cases
- Sync AR and collection status back to customer success tools ahead of renewals.
- Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.
- Write bounces, spam reports, and unsubscribes back to the CRM to keep email opt-in status accurate everywhere
- Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting
Where SendGrid tracks people or companies: one identity
A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.
Where SendGrid is a docs or knowledge workspace: reference data kept fresh
Figures teams rely on, like customer status or outstanding balances, stay current wherever SendGrid surfaces them instead of going stale after a one-time paste.
Where SendGrid handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Rillet next to the customer they are helping, without logging into the finance system.

How the Rillet and SendGrid connectors work
Rillet
- Integration surface
- REST API (OpenAPI-specified, with production and sandbox environments)
- Authentication
- API key generated in Rillet (Organization Setting -> API Access); uncheck Read Only for bidirectional sync, check Read Only for one-way sync
- Change detection
- Near real-time updates via change tracking; incremental sync per object, with delete detection (some objects checked every 1h or 4h)
- Capabilities
- read · write · CDC · webhooks
- Rate limits
- Subject to the platform's API rate limits.
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
Rillet and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Rillet and SendGrid: authenticate both systems, choose the objects to sync (such as Rillet's Invoice and Credit Memo), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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 Rillet and SendGrid records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Rillet and SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Rillet–SendGrid integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Rillet and SendGrid. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Rillet: Near real-time updates via change tracking; incremental sync per object, with delete detection (some objects checked every 1h or 4h). 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 Rillet side: Account, Customer, Vendor, Invoice, plus custom fields where Rillet exposes them. On the SendGrid side: Senders, Single Sends, Unsubscribe Groups, Email Activity. Stacksync auto-detects both schemas and converts types between the two systems.
