Why teams connect Amazon RDS and SendGrid

Mirror SendGrid's data into Amazon RDS so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Connecting SendGrid to Amazon RDS turns email delivery and audience data into queryable database records. Email Activity and Contacts sync into RDS Tables for engagement analysis, and rows written to the database update SendGrid Lists and Segments so audiences stay driven by operational data.

Stacksync mirrors Single Sends, Unsubscribe Groups, Email Activity, Contacts from SendGrid into Stored Procedures, Databases, Schemas, Tables in Amazon RDS and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into SendGrid, so the tool and the database never disagree.

Common use cases

  • 01 Join Email Activity with customer tables in RDS to measure engagement by account or plan.
  • 02 Keep SendGrid Lists current automatically as users sign up or churn in the application database.
  • 03 Audit sender configuration by querying Senders and Categories records alongside campaign data in SQL.
  • 04 Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments

Common sync patterns

Email engagement warehouse

SendGrid Email Activity replicates into Amazon RDS Tables for SQL analysis of delivery and engagement.

Audience sync

Rows in RDS Tables update SendGrid Contacts and List membership from application or billing data.

Segment management

Segments and Categories sync to RDS Views so campaign targeting reflects the latest database state.

What you can sync between Amazon RDS 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.

Amazon RDS objects SendGrid objects How this pairing syncs
Primary and Unique Keys Match keys for idempotent upserts. Single Sends One-off marketing campaigns whose stats are read back for reporting. Primary and Unique Keys is specific to Amazon RDS and Single Sends to SendGrid — each maps to any object or custom field on the other side.
Read Replicas Low-impact read endpoints often used as the source side of a sync. Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. Read Replicas is specific to Amazon RDS and Unsubscribe Groups to SendGrid — each maps to any object or custom field on the other side.
Stored Procedures Engine-specific logic that can react to synced rows. Email Activity Synced with incremental and full sync per the Stacksync docs. Stored Procedures is specific to Amazon RDS and Email Activity to SendGrid — each maps to any object or custom field on the other side.
Databases Engine-level databases on the instance that scope a sync's reads and writes. Contacts Marketing recipients upserted from CRM or database records, including custom field values. Databases is specific to Amazon RDS and Contacts to SendGrid — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to isolate synced tables. List Synced with incremental and full sync per the Stacksync docs. Schemas is specific to Amazon RDS and List to SendGrid — each maps to any object or custom field on the other side.
Tables The core sync target; rows map to records in connected SaaS systems. Segments Query-based contact groups whose membership SendGrid computes from contact fields. Tables is specific to Amazon RDS and Segments to SendGrid — each maps to any object or custom field on the other side.

How changes propagate between Amazon RDS 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.

Amazon RDS SendGrid Sub-second propagation

DetectionChanges in Amazon RDS are captured at the source via change data capture — no polling loop against its API. Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC.

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

SendGrid Amazon RDS 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 applied to Amazon RDS as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Amazon RDS: No API rate limits; throughput depends on instance class, storage IOPS, and connection limits.
  • SendGrid: Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes.
