Why teams connect SendGrid and Twilio
Stop re-entering the same information in SendGrid and Twilio: 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 Incoming Phone Numbers, Outgoing Caller IDs, Accounts, Roles in Twilio 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
- Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
- Reconcile transactional email activity with support tickets so agents see what a customer was sent
- Mirror Verify outcomes into a user database to gate onboarding steps on completed phone verification.
- Push Twilio usage records into a finance database for per-customer communication cost allocation.
Where one tool produces events: mirror them in the other
Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
Where Twilio is where the team documents or plans: keep its data fed
Information that originates in SendGrid stays current in Twilio 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.
What you can sync between SendGrid and Twilio
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 | Twilio objects | |
|---|---|---|
| Single Sends One-off marketing campaigns whose stats are read back for reporting. | Accounts Synced with incremental and full sync per the Stacksync docs. | |
| Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. | Roles Synced with incremental and full sync per the Stacksync docs. | |
| Email Activity Synced with incremental and full sync per the Stacksync docs. | Addresses Synced with incremental and full sync per the Stacksync docs. | |
| Contacts Marketing recipients upserted from CRM or database records, including custom field values. | Flows Synced with incremental and full sync per the Stacksync docs. | |
| List Synced with incremental and full sync per the Stacksync docs. | Usage Records Aggregated usage and spend data synced into finance systems for cost tracking. | |
| Segments Query-based contact groups whose membership SendGrid computes from contact fields. | Messages SMS, MMS, and WhatsApp messages with delivery status; synced to log outreach in CRMs and databases. |

How the SendGrid and Twilio connectors work
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
Twilio
- Integration surface
- REST API (per-product APIs for Messaging, Voice, Conversations, Verify)
- Authentication
- Account SID + Auth Token (copied from Twilio Console Account Info and entered into the Stacksync Twilio connector)
- Change detection
- Status callback webhooks per message and call, plus polling of resource lists for backfill
- Capabilities
- read · write · webhooks

FAQ
SendGrid and Twilio integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between SendGrid and Twilio: authenticate both systems, choose the objects to sync (such as SendGrid's Single Sends and Unsubscribe Groups), 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 SendGrid and Twilio records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed SendGrid and Twilio connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom SendGrid–Twilio integration in-house.
-
Yes — Stacksync ships production-grade connectors for both SendGrid and Twilio. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection 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. On Twilio: Status callback webhooks per message and call, plus polling of resource lists for backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the SendGrid side: List, Segments, Categories, Senders, plus custom fields where SendGrid exposes them. On the Twilio side: Incoming Phone Numbers, Outgoing Caller IDs, Accounts, Roles. Stacksync auto-detects both schemas and converts types between the two systems.
