Why teams connect DEAR Inventory and SendGrid
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between SendGrid and DEAR Inventory.
The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. SendGrid is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.
Stacksync syncs Contacts, List, Segments, Categories in SendGrid with Locations, Products, Stock levels, Sale orders in DEAR Inventory bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.
Common use cases
- 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
- Land orders, costs, and inventory movements in a warehouse for margin and stock-turn reporting.
- Keep supplier and purchase order data aligned with the accounting system for accrual accuracy.
Master data corrections travel
A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
Where SendGrid faces customers and DEAR Inventory carries account records
Order, invoice, or account status from DEAR Inventory appears alongside the customer in SendGrid, so front-line teams answer from live data.
Where SendGrid collects payments: transactions post through

FAQ
DEAR Inventory and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between DEAR Inventory and SendGrid: authenticate both systems, choose the objects to sync (such as DEAR Inventory's Locations and Products), 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 DEAR Inventory and SendGrid: Master data corrections travel; Where SendGrid faces customers and DEAR Inventory carries account records; Where SendGrid collects payments: transactions post through. A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
-
DEAR Inventory: REST API. Authentication: Account ID plus application key sent as request headers. 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"). Stacksync manages authentication, retries, and rate limits on both sides.
-
SendGrid: Email Activity data retention depends on subscription level (typically 7 days by default, 30 days with the add-on). DEAR Inventory: Inventory availability is derived per location from transactions (receipts, sales, adjustments, transfers), so synced stock figures reflect movement history rather than a single editable field. Stacksync's field mapping accounts for these differences between DEAR Inventory and SendGrid without custom code.
-
