Why teams connect SendGrid and Smartsheet
Stop re-entering the same information in SendGrid and Smartsheet: Stacksync keeps the records they share consistent in real time, in both directions.
Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.
Stacksync syncs List, Segments, Categories, Senders in SendGrid with Reports, Attachments, Discussions and Comments, Users and Groups in Smartsheet in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.
Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.
Common use cases
- 01 Reconcile transactional email activity with support tickets so agents see what a customer was sent
- 02 Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
- 03 Trigger downstream actions in an operational database when a Row's status Cell changes, using sheet webhooks for near-real-time updates.
- 04 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
Common sync patterns
Where Smartsheet is where the team documents or plans: keep its data fed
Information that originates in SendGrid stays current in Smartsheet instead of going stale after a one-time paste.
Handoffs between teams
When work started in one tool continues in the other, the shared fields travel with it automatically.
Where both tools track people or companies: one consistent record
Contact and company details corrected in either tool update the other, so nobody works from the old version.
What you can sync between SendGrid and Smartsheet
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 | Smartsheet objects | How this pairing syncs | |
|---|---|---|---|
| Senders Synced with incremental and full sync per the Stacksync docs. | Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. | Senders is specific to SendGrid and Columns to Smartsheet — each maps to any object or custom field on the other side. | |
| Single Sends One-off marketing campaigns whose stats are read back for reporting. | Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. | Single Sends is specific to SendGrid and Cells to Smartsheet — each maps to any object or custom field on the other side. | |
| Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. | Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. | Unsubscribe Groups is specific to SendGrid and Reports to Smartsheet — each maps to any object or custom field on the other side. | |
| Email Activity Synced with incremental and full sync per the Stacksync docs. | Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. | Email Activity is specific to SendGrid and Attachments to Smartsheet — each maps to any object or custom field on the other side. | |
| Contacts Marketing recipients upserted from CRM or database records, including custom field values. | Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. | Contacts is specific to SendGrid and Discussions and Comments to Smartsheet — each maps to any object or custom field on the other side. | |
| List Synced with incremental and full sync per the Stacksync docs. | Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. | List is specific to SendGrid and Users and Groups to Smartsheet — each maps to any object or custom field on the other side. |
How changes propagate between SendGrid and Smartsheet
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
SendGrid Smartsheet Sub-second propagation
DetectionSendGrid notifies Stacksync of record changes through webhook events. Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint.
DeliveryEach detected change is written to Smartsheet through its API, with automatic retries and rate-limit backoff.
Smartsheet SendGrid Sub-second propagation
DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.
DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
- Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.

FAQ
SendGrid and Smartsheet integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between SendGrid and Smartsheet: authenticate both systems, choose the objects to sync (such as SendGrid's Senders and Single Sends), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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"). Smartsheet: REST API (v2.0). Authentication: OAuth 2.0 authorization-code flow, or a raw/personal API access token passed as a Bearer header. 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). Smartsheet: Row add and update calls are limited to 500 rows per request, so large syncs are chunked. Stacksync's field mapping accounts for these differences between SendGrid and Smartsheet 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 Smartsheet records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed SendGrid and Smartsheet connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom SendGrid–Smartsheet integration in-house.
-
Yes — Stacksync ships production-grade connectors for both SendGrid and Smartsheet. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
