Why teams connect Amazon SES and Kustomer

Keep Kustomer and Amazon SES working from the same contacts, and log every call, message, and meeting back on the record, in real time and in both directions.

Kustomer holds the people the business talks to: the contacts, their phone numbers and email addresses, and which rep owns the relationship. Amazon SES is where the talking happens, whether that is calls, texts, email, or meetings. The two depend on the same people, and when the contact list in one drifts from the other, outreach goes to stale numbers and the record of what was said never makes it back to the account.

Stacksync syncs Users, Teams, Tags, Notes in Kustomer with Verified Identities, Configuration Sets, Sending Events, Messages (SendEmail / SendBulkEmail) in Amazon SES field by field, in real time, and in both directions. Current contact details flow out to Amazon SES so it can reach the right person, and the calls, messages, and meetings Amazon SES produces flow back onto the matching record in Kustomer. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • 02 Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
  • 03 Write bounced and complained addresses from the SES Suppression List back onto CRM and marketing records so other tools stop emailing them.
  • 04 Keep Email Templates in sync from a CMS or Git-backed source into SES via CreateEmailTemplate and UpdateEmailTemplate across environments.

Common sync patterns

New contacts reachable right away

A contact created or updated in Kustomer appears in Amazon SES within seconds, so outreach starts without exporting a list or re-keying numbers.

Where Amazon SES reaches out: contacts kept current

Names, phone numbers, email addresses, and the owning rep from Kustomer stay current in Amazon SES, so every call, text, or email goes to the right person at the right address.

Calls, messages, and meetings on the record

Activity handled in Amazon SES appears on the matching contact and account in Kustomer, so the next person sees the full history without leaving the CRM.

What you can sync between Amazon SES and Kustomer

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 Kustomer objects How this pairing syncs
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). Notes Internal annotations carry context alongside synced conversations. Sending Events is specific to Amazon SES and Notes to Kustomer — 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. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Messages (SendEmail / SendBulkEmail) is specific to Amazon SES and Customers to Kustomer — 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. Conversations Support threads across channels sync outward for analytics and CRM context. Contacts is specific to Amazon SES and Conversations to Kustomer — 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. Messages Individual messages within conversations support full-thread replication. Contact Lists is specific to Amazon SES and Messages to Kustomer — 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. Companies Organization records group customers and map to CRM accounts. Email Templates is specific to Amazon SES and Companies to Kustomer — each maps to any object or custom field on the other side.
Suppression List Addresses auto-added on bounce or complaint; read with ListSuppressedDestinations and written with Put/DeleteSuppressedDestination to control re-sends. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. Suppression List is specific to Amazon SES and Custom Objects (Klasses) to Kustomer — each maps to any object or custom field on the other side.

How changes propagate between Amazon SES and Kustomer

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

Kustomer Amazon SES Sub-second propagation

DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.

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.
  • Kustomer: Subject to the platform's API rate limits.
