Why teams connect Amazon DynamoDB and Lemlist

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

Engineers integrate with tools like Lemlist through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Amazon DynamoDB.

Stacksync mirrors Leads, Activities, Unsubscribes, Webhooks from Lemlist into DynamoDB Streams, Global Tables, Time to Live (TTL), Tables in Amazon DynamoDB 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 Lemlist, so the tool and the database never disagree.

Common use cases

  • 01 Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • 02 Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • 03 Use DynamoDB Streams as a change-data-capture source to push item INSERT, MODIFY, and REMOVE events into a CRM, search index, or operational database in near-real-time.
  • 04 Backfill or migrate records into DynamoDB from another database using BatchWriteItem, then keep the two stores in continuous sync.

Common sync patterns

React to changes as they happen

Updates in Lemlist arrive as row changes in Amazon DynamoDB, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Lemlist with a query

Records from Lemlist are ordinary rows in Amazon DynamoDB; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Amazon DynamoDB and Lemlist

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 DynamoDB objects Lemlist objects How this pairing syncs
Time to Live (TTL) Per-item expiry timestamps; DynamoDB deletes expired items in the background and emits a Streams REMOVE record for each deletion. Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Time to Live (TTL) is specific to Amazon DynamoDB and Webhooks to Lemlist — each maps to any object or custom field on the other side.
Tables Top-level containers, each with a partition key and optional sort key; Stacksync syncs a table as a stream of items with full read and write via PutItem, UpdateItem, and DeleteItem. Team Members Sender and seat records map outreach activity to reps in other systems. Tables is specific to Amazon DynamoDB and Team Members to Lemlist — each maps to any object or custom field on the other side.
Items Individual schemaless records (attributes up to 400 KB each); read with GetItem, Query, and Scan and written with PutItem or BatchWriteItem, so write is supported here. Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Items is specific to Amazon DynamoDB and Campaigns to Lemlist — each maps to any object or custom field on the other side.
Global secondary indexes (GSIs) Alternate key projections that let you Query by non-key attributes without a full table Scan; read-only views maintained automatically by DynamoDB. Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Global secondary indexes (GSIs) is specific to Amazon DynamoDB and Leads to Lemlist — each maps to any object or custom field on the other side.
Local secondary indexes (LSIs) Extra sort keys within the same partition key, defined at table creation; queried like the base table for alternate access patterns. Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Local secondary indexes (LSIs) is specific to Amazon DynamoDB and Activities to Lemlist — each maps to any object or custom field on the other side.
DynamoDB Streams Ordered item-level change records (INSERT, MODIFY, REMOVE) with old/new image views and 24-hour retention; the native change-data-capture source Stacksync reads for near-real-time sync. Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. DynamoDB Streams is specific to Amazon DynamoDB and Unsubscribes to Lemlist — each maps to any object or custom field on the other side.

How changes propagate between Amazon DynamoDB and Lemlist

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 DynamoDB Lemlist Sub-second propagation

DetectionChanges in Amazon DynamoDB are captured at the source via change data capture — no polling loop against its API. DynamoDB Streams emit ordered item-level change records (INSERT, MODIFY, REMOVE) with KEYS_ONLY, NEW_IMAGE, OLD_IMAGE, or NEW_AND_OLD_IMAGES views.

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

Lemlist Amazon DynamoDB Sub-second propagation

DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.

DeliveryEach detected change is applied to Amazon DynamoDB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Amazon DynamoDB: Throughput is metered in read/write capacity units (provisioned or on-demand): 1 WCU = one 1 KB write per second, 1 RCU = one strongly-consistent 4 KB read per second. Exceeding capacity or the ~3,000 RCU / 1,000 WCU per-partition ceiling returns ProvisionedThroughputExceededException with throttling.
  • Lemlist: Subject to the platform's API rate limits.

How the Amazon DynamoDB and Lemlist connectors work

Amazon DynamoDB

Integration surface
AWS SDK / low-level HTTPS JSON API at dynamodb.<region>.amazonaws.com (PutItem, GetItem, UpdateItem, DeleteItem, Query, Scan, BatchWriteItem, TransactWriteItems), plus PartiQL (ExecuteStatement) for SQL-style access and DynamoDB Streams for change capture.
Authentication
AWS Signature Version 4 (SigV4) signed requests using an IAM access key ID and secret key, or temporary STS credentials from an assumed IAM role; IAM policies scope access down to table and item level.
Change detection
DynamoDB Streams emit ordered item-level change records (INSERT, MODIFY, REMOVE) with KEYS_ONLY, NEW_IMAGE, OLD_IMAGE, or NEW_AND_OLD_IMAGES views and 24-hour retention, read via shard iterators (or Kinesis Data Streams for longer retention). No native HTTP webhooks.
