Why teams connect AWS S3 and BetterContact

Get the data locked inside BetterContact into AWS S3 as live tables, and send results back where BetterContact can use them, without writing a pipeline.

BetterContact is a read-only source: Stacksync reads its data in real time and delivers it into AWS S3, so AWS S3 always reflects the current state of BetterContact — without exports, scripts, or schedulers.

Whatever BetterContact is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Common use cases

  • 01 Validate catch-all email addresses before sending to protect sender domain reputation.
  • 02 Enrich new CRM leads with verified emails and mobile numbers as they are created, writing results back to the CRM record.
  • 03 Archive change history from ongoing syncs as timestamped files for audit and replay.
  • 04 Ingest partner or vendor file drops (CSV, JSON, Parquet) from a bucket into a database or CRM as records.

Common sync patterns

Where BetterContact accepts updates: operational write-back

Segments, scores, or reference values computed in AWS S3 sync back onto records in BetterContact, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in AWS S3 preserves a queryable record even as data ages out of BetterContact or gets changed inside it.

Analytics on BetterContact's data

Records and events from BetterContact land in AWS S3 as queryable tables, current within seconds and ready to join with the rest of the warehouse.

What you can sync between AWS S3 and BetterContact

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.

AWS S3 objects BetterContact objects How this pairing syncs
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Company Company data returned with each contact: name, domain, HQ location, industry, employee count. Event Notifications is specific to AWS S3 and Company to BetterContact — each maps to any object or custom field on the other side.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Lead Finder Search Prospect discovery by people and company filters, returning enriched lead profiles. Access Points is specific to AWS S3 and Lead Finder Search to BetterContact — each maps to any object or custom field on the other side.
Multipart Uploads The mechanism used to write large export files reliably. Enrichment Request Batch or single submissions of up to 100 contacts per request for waterfall enrichment. Multipart Uploads is specific to AWS S3 and Enrichment Request to BetterContact — each maps to any object or custom field on the other side.
Buckets Top-level containers a sync targets; region and policy are set at this level. Enriched Contact Verified work emails and mobile numbers with job title, LinkedIn profile, location, and skills. Buckets is specific to AWS S3 and Enriched Contact to BetterContact — each maps to any object or custom field on the other side.

How changes propagate between AWS S3 and BetterContact

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.

AWS S3 BetterContact Sub-second propagation

DetectionAWS S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge.

DeliveryBetterContact does not accept inbound record writes, so this direction carries requests rather than records: BetterContact's output flows back as field updates on the originating AWS S3 records.

BetterContact AWS S3 Sub-second propagation

DetectionBetterContact notifies Stacksync of record changes through webhook events. Job-based delivery — enrichment results arrive by webhook push or polling of the results endpoint.

DeliveryEach detected change is written to AWS S3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • AWS S3: Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes.
  • BetterContact: Batches capped at 100 contacts per enrichment request.
