Why teams connect Azure Service Bus and SendGrid

Connect the tickets, records, and events in SendGrid to the systems engineering runs in Azure Service Bus, kept current in real time and in both directions.

SendGrid is where customer-facing and operational work happens: the tickets, conversations, contacts, and records a team touches every day. Azure Service Bus is where engineering runs the systems behind that work — the issue trackers, message brokers, directories, and monitors that keep services moving. The same items, people, and events matter to both, and when the only link between them is a manual hand-off or an overnight export, each side acts on a stale copy of what the other already knows.

Stacksync syncs Single Sends, Unsubscribe Groups, Email Activity, Contacts in SendGrid with Scheduled / deferred messages, Queues, Topics, Subscriptions in Azure Service Bus field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync maps the overlap, resolves conflicts by rules you set, and keeps every copy current, with no middleware to build and no API limits to babysit.

Common use cases

  • 01 Write bounces, spam reports, and unsubscribes back to the CRM to keep email opt-in status accurate everywhere
  • 02 Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting
  • 03 Send new and changed database rows as messages to a Service Bus queue or topic so multiple downstream consumers process the change stream independently.
  • 04 Receive messages from a queue or subscription with an AMQP receiver and write them into a Postgres or warehouse table for durable, SQL-queryable storage.

Common sync patterns

Where Azure Service Bus watches operations: live volumes for visibility

Open items, throughput, and error counts from SendGrid replicate into Azure Service Bus, so the operational view reflects what is actually happening in the business.

One shared record across both systems

Where both systems keep records for the same contacts, items, or users, a correction in either updates the other, ending dual maintenance and keeping IDs aligned for every other flow.

Where Azure Service Bus tracks engineering work: requests become issues

A ticket or request raised in SendGrid opens or updates a matching issue in Azure Service Bus, and status, comments, and resolution flow back, so support and engineering work the same item instead of retyping it.

What you can sync between Azure Service Bus 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.

Azure Service Bus objects SendGrid objects How this pairing syncs
Scheduled / deferred messages Messages enqueued for future delivery at a set time, or deferred and set aside by sequence number for retrieval later, out of the normal receive order. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. Scheduled / deferred messages is specific to Azure Service Bus and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side.
Queues Point-to-point entity: a sender writes messages and one competing consumer at a time receives them under PeekLock, then completes or abandons each message. Email Activity Synced with incremental and full sync per the Stacksync docs. Queues is specific to Azure Service Bus and Email Activity to SendGrid — each maps to any object or custom field on the other side.
Topics Publish/subscribe entity a publisher sends to; each message is fanned out to every subscription whose filter rules match, so many consumers get their own copy. Contacts Marketing recipients upserted from CRM or database records, including custom field values. Topics is specific to Azure Service Bus and Contacts to SendGrid — each maps to any object or custom field on the other side.
Subscriptions A virtual queue attached to a topic; a consumer receives its own stream of matching messages here, independent of other subscriptions on the same topic. List Synced with incremental and full sync per the Stacksync docs. Subscriptions is specific to Azure Service Bus and List to SendGrid — each maps to any object or custom field on the other side.
Messages The synced unit: a body plus system and user properties, MessageId, SessionId, and TTL; capped at 256 KB on Standard and up to 100 MB on Premium over AMQP. Segments Query-based contact groups whose membership SendGrid computes from contact fields. Messages is specific to Azure Service Bus and Segments to SendGrid — each maps to any object or custom field on the other side.
Rules / Filters SQL or correlation filters on a subscription that decide which topic messages it receives; a rule can also add or modify properties via a filter action. Categories Synced with incremental and full sync per the Stacksync docs. Rules / Filters is specific to Azure Service Bus and Categories to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between Azure Service Bus and SendGrid

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.

Azure Service Bus SendGrid Interval-based propagation

DetectionStacksync polls Azure Service Bus for changes on an incremental schedule, reading only records changed since the previous pass. Consumes messages as they arrive: an AMQP receiver holds an open connection and takes messages with PeekLock (lock, then complete/abandon) or.

DeliveryEach detected change is written to SendGrid through its API, with automatic retries and rate-limit backoff.

SendGrid Azure Service Bus 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 Azure Service Bus through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Azure Service Bus: Standard tier throttles around 1,000 operations/second and returns a ServerBusy error; Premium provisions dedicated messaging units (1, 2, 4, 8, or 16) for isolated, predictable throughput. Up to 5,000 concurrent AMQP connections per namespace and 5,000 concurrent receive requests per entity.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.

How the Azure Service Bus and SendGrid connectors work

Azure Service Bus

Integration surface
AMQP 1.0 messaging protocol plus an HTTP/REST API; entities live under a namespace at <namespace>.servicebus.windows.net (legacy SBMP also supported)
Authentication
Microsoft Entra ID (Azure AD) RBAC with managed identities - roles Azure Service Bus Data Owner, Data Sender, and Data Receiver - or Shared Access Signature (SAS) policies scoped with Manage, Send, and Listen claims
Change detection
Consumes messages as they arrive: an AMQP receiver holds an open connection and takes messages with PeekLock (lock, then complete/abandon) or ReceiveAndDelete. No modified-date polling and no native HTTP push; Azure Event Grid can separately raise an 'active messages available' event for intermittent receivers
