Why teams connect Amazon SES and Apache Cassandra

Turn the messages, calls, and events Amazon SES handles into live rows in Apache Cassandra, 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 Apache Cassandra next to everything else.

Stacksync mirrors Sending Events, Messages (SendEmail / SendBulkEmail), Contacts, Contact Lists from Amazon SES into Tables, Partitions and Rows, Materialized Views, Secondary Indexes in Apache Cassandra 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 Stream SES sending events (delivery, bounce, complaint, open, click) from a configuration-set event destination into a warehouse for deliverability reporting.
  • 02 Write bounced and complained addresses from the SES Suppression List back onto CRM and marketing records so other tools stop emailing them.
  • 03 Feed Cassandra change streams into search indexes or caches that must track the source of truth.
  • 04 Consolidate data from multiple keyspaces or clusters into one reporting store.

Common sync patterns

Communication history as database rows

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

Trigger outbound communication from the database

Write a row to a synced table in Apache Cassandra and Stacksync propagates it into Amazon SES, so your code sends the message, places the call, or schedules the meeting without integration glue.

One contact list across both

Recipients and contacts stay consistent between Amazon SES and Apache Cassandra, so a phone number or email corrected on either side is current the next time either system uses it.

What you can sync between Amazon SES and Apache Cassandra

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 SES objects Apache Cassandra objects How this pairing syncs
Configuration Sets Named send-time rule groups that attach event destinations, IP pools, and suppression options; managed via Create/List ConfigurationSet operations. Counters Increment-only counter columns, usually read-only in syncs. Configuration Sets is specific to Amazon SES and Counters to Apache Cassandra — each maps to any object or custom field on the other side.
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). Keyspaces Top-level namespaces with replication settings that scope a sync connection. Sending Events is specific to Amazon SES and Keyspaces to Apache Cassandra — each maps to any object or custom field on the other side.
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. Tables Wide-column tables addressed by partition key, the unit of row-level sync. Messages (SendEmail / SendBulkEmail) is specific to Amazon SES and Tables to Apache Cassandra — each maps to any object or custom field on the other side.
Contacts Subscribers in the contact list with per-topic opt-in state; CRUD via CreateContact/ListContacts/UpdateContact/DeleteContact, each carrying a LastUpdatedTimestamp for polling. Partitions and Rows Records located by partition and clustering keys during reads and upserts. Contacts is specific to Amazon SES and Partitions and Rows to Apache Cassandra — each maps to any object or custom field on the other side.
Contact Lists One list per AWS account, subdivided into Topics that group subscriptions; read and write via CreateContactList and GetContactList. Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Contact Lists is specific to Amazon SES and Materialized Views to Apache Cassandra — each maps to any object or custom field on the other side.
Email Templates Reusable subject/HTML/text templates with replacement variables; synced via CreateEmailTemplate, GetEmailTemplate, ListEmailTemplates, and UpdateEmailTemplate. Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Email Templates is specific to Amazon SES and Secondary Indexes to Apache Cassandra — each maps to any object or custom field on the other side.

How changes propagate between Amazon SES and Apache Cassandra

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 SES Apache Cassandra 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 written to Apache Cassandra through its API, with automatic retries and rate-limit backoff.

Apache Cassandra Amazon SES Sub-second propagation

DetectionChanges in Apache Cassandra are captured at the source via change data capture — no polling loop against its API. Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns.

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

Rate-limit considerations

  • 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.
  • Apache Cassandra: No API quotas; throughput is governed by cluster capacity and consistency-level choices.
