Why teams connect Lemlist and VoltDB

Mirror Lemlist's data into VoltDB 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 VoltDB.

Stacksync mirrors Leads, Activities, Unsubscribes, Webhooks from Lemlist into Partitioned Tables, Replicated Tables, Stored Procedures, Materialized Views in VoltDB 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 Stream committed VoltDB results out through export targets into a warehouse for historical analysis.
  • 04 Keep product, plan, or entitlement state consistent between VoltDB and back-office systems.

Common sync patterns

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 VoltDB; join them, index them, and use them in application logic without touching the vendor API.

Automate Lemlist from your codebase

Write to the synced tables in VoltDB and Stacksync propagates the change into Lemlist, replacing custom integration code.

What you can sync between Lemlist and VoltDB

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.

Lemlist objects VoltDB objects How this pairing syncs
Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. Leads is specific to Lemlist and Partitioned Tables to VoltDB — each maps to any object or custom field on the other side.
Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. Activities is specific to Lemlist and Replicated Tables to VoltDB — each maps to any object or custom field on the other side.
Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Stored Procedures Precompiled transactional units that serve as the primary write interface. Unsubscribes is specific to Lemlist and Stored Procedures to VoltDB — each maps to any object or custom field on the other side.
Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. Webhooks is specific to Lemlist and Materialized Views to VoltDB — each maps to any object or custom field on the other side.
Team Members Sender and seat records map outreach activity to reps in other systems. Streams Insert-only constructs that feed the export subsystem with committed rows. Team Members is specific to Lemlist and Streams to VoltDB — each maps to any object or custom field on the other side.
Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. Campaigns is specific to Lemlist and Export Targets and Topics to VoltDB — each maps to any object or custom field on the other side.

How changes propagate between Lemlist and VoltDB

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.

Lemlist VoltDB 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 VoltDB as a row-level write, with types converted between the two schemas.

VoltDB Lemlist Interval-based propagation

DetectionStacksync polls VoltDB for changes on an incremental schedule, reading only records changed since the previous pass. Export streams and topics push committed changes to configured targets.

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

Rate-limit considerations

  • Lemlist: Subject to the platform's API rate limits.
  • VoltDB: No API rate limits; throughput is bounded by partition count and cluster sizing.
