Why teams connect Amazon RDS and Amazon SES

Turn the messages, calls, and events Amazon SES handles into live rows in Amazon RDS, and write back to trigger new outbound communication, with both sides in sync in seconds.

Engineers reach communications tools like Amazon SES through APIs, which means auth tokens, webhooks, delivery callbacks, and rate limits, all maintained forever and all shaped differently for every tool. The data those tools produce, who was contacted, what was sent, and what came back, would be simple to use if it lived in Amazon RDS next to everything else.

Stacksync mirrors Suppression List, Verified Identities, Configuration Sets, Sending Events from Amazon SES into Primary and Unique Keys, Read Replicas, Stored Procedures, Databases in Amazon RDS and keeps both sides in sync in real time. Communication activity lands in the database as ordinary rows you can query and join, and rows your code writes, such as a queued outbound message or an updated contact, flow back into Amazon SES so the tool and the database never disagree.

There is no webhook endpoint to host, no rate limit to babysit, and no nightly export that leaves your services reading yesterday's activity.

Common use cases

  • 01 Two-way sync Contacts and their topic subscription state between the SES contact list and a Postgres database or CRM so opt-outs propagate in both directions.
  • 02 Push warehouse or CRM audience segments into SES as Contacts using CreateContact or a bulk CreateImportJob (up to 1M contacts per job) to feed marketing sends.
  • 03 Bi-directional sync between an RDS database and a CRM so application data and sales data stay consistent without custom integration code
  • 04 Mirror SaaS objects into RDS tables so product features can join business data with application data in one query

Common sync patterns

React to activity as it happens

Sends, replies, answered calls, or completed meetings arrive in Amazon RDS as row changes, so triggers, jobs, and services can respond in near real time.

One integration pattern for every channel

Each communications tool looks like tables in the database, so adding email, voice, or messaging is configuration rather than a new codebase.

Communication history as database rows

Every message, call, or event Amazon SES records becomes rows in Amazon RDS, ready to query, join with your own data, and report on without touching the vendor API.

What you can sync between Amazon RDS and Amazon SES

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 Amazon SES objects How this pairing syncs
Primary and Unique Keys Match keys for idempotent upserts. Configuration Sets Named send-time rule groups that attach event destinations, IP pools, and suppression options; managed via Create/List ConfigurationSet operations. Primary and Unique Keys is specific to Amazon RDS and Configuration Sets to Amazon SES — 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. Sending Events Per-message send, delivery, bounce, complaint, open, and click events; not on any API, read from a configuration-set event destination (SNS/EventBridge/Firehose). Read Replicas is specific to Amazon RDS and Sending Events to Amazon SES — each maps to any object or custom field on the other side.
Stored Procedures Engine-specific logic that can react to synced rows. Messages (SendEmail / SendBulkEmail) Outbound email is produced via SendEmail and SendBulkEmail, accepting raw MIME or a template plus destination list. Send-only; there is no message store to read back. Stored Procedures is specific to Amazon RDS and Messages (SendEmail / SendBulkEmail) to Amazon SES — 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 Subscribers in the contact list with per-topic opt-in state; CRUD via CreateContact/ListContacts/UpdateContact/DeleteContact, each carrying a LastUpdatedTimestamp for polling. Databases is specific to Amazon RDS and Contacts to Amazon SES — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to isolate synced tables. Contact Lists One list per AWS account, subdivided into Topics that group subscriptions; read and write via CreateContactList and GetContactList. Schemas is specific to Amazon RDS and Contact Lists to Amazon SES — 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. Email Templates Reusable subject/HTML/text templates with replacement variables; synced via CreateEmailTemplate, GetEmailTemplate, ListEmailTemplates, and UpdateEmailTemplate. Tables is specific to Amazon RDS and Email Templates to Amazon SES — each maps to any object or custom field on the other side.

How changes propagate between Amazon RDS and Amazon SES

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 Amazon SES 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 Amazon SES through its API, with automatic retries and rate-limit backoff.

Amazon SES Amazon RDS Sub-second propagation

DetectionAmazon SES notifies Stacksync of record changes through webhook events. Message events (delivery, bounce, complaint, open, click) are pushed in near real time through configuration-set event destinations.

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.
  • Amazon SES: Every SES API action except SendEmail, SendRawEmail, and SendTemplatedEmail is throttled to 1 request/second per Region; the send rate and 24-hour sending quota are account-specific, adjustable, and per Region.
