Why teams connect Lemlist and Ukg Ready

Keep the people, teams, and status that Lemlist and Ukg Ready share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.

Each tool in Lemlist keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. Ukg Ready is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.

Stacksync syncs Unsubscribes, Webhooks, Team Members, Campaigns in Lemlist with Compensation, Timesheet Entries, Accruals / Time Off, Payroll (Earnings / Deductions / Employee Payroll Runs) in Ukg Ready bi-directionally and in real time. A person added, moved, or offboarded in Ukg Ready creates or updates the matching user in Lemlist within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Lemlist captures details of its own, such as a corrected contact or a login identity, those can flow back to Ukg Ready in whichever direction you configure.

Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.

Common use cases

  • 01 Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
  • 02 Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • 03 Two-way sync Employees and Employment/Position records with an operational Postgres database so internal apps and IT provisioning read job title, department, and status in SQL while HR edits in UKG Ready.
  • 04 Import computed Earnings and deductions into UKG Ready payroll runs from a warehouse or external time-tracking system ahead of each pay period.

Common sync patterns

Offboarding: no standing access after a departure

When someone is marked as leaving in Ukg Ready, the matching account in Lemlist is deactivated or flagged, so departures do not leave open access behind.

One employee directory

A person's name, title, contact details, or status corrected in either system updates the other, so both sides stop maintaining separate copies of the same person.

Org and team structure kept current

Department, team, and reporting-line changes from Ukg Ready keep the groups, queues, or projects in Lemlist assigned to the right people.

What you can sync between Lemlist and Ukg Ready

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 Ukg Ready objects How this pairing syncs
Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Employees Core person records (demographics, contact info, status, work location); synced two-way and mapped to HRIS or person tables in a database. Campaigns is specific to Lemlist and Employees to Ukg Ready — each maps to any object or custom field on the other side.
Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Employment / Positions Job title, department, employment type, hire and termination dates; read for org modeling and written when roles change. Leads is specific to Lemlist and Employment / Positions to Ukg Ready — 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. Compensation Salary or hourly rate, pay frequency, and FLSA status; often mastered elsewhere and written onto the employee record, or read into finance. Activities is specific to Lemlist and Compensation to Ukg Ready — 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. Timesheet Entries Time-and-attendance punches, hours worked, and breaks; written from external time systems and read into warehouses for labor-cost reporting. Unsubscribes is specific to Lemlist and Timesheet Entries to Ukg Ready — each maps to any object or custom field on the other side.
Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Accruals / Time Off PTO balances, requests, and approver status; read for liability reporting and requests can be created against employee records. Webhooks is specific to Lemlist and Accruals / Time Off to Ukg Ready — 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. Payroll (Earnings / Deductions / Employee Payroll Runs) Earnings and deductions can be imported into pay runs; Employee Payroll Runs (gross, net, taxes) read back for GL posting and analytics. Team Members is specific to Lemlist and Payroll (Earnings / Deductions / Employee Payroll Runs) to Ukg Ready — each maps to any object or custom field on the other side.

How changes propagate between Lemlist and Ukg Ready

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 Ukg Ready Sub-second propagation

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

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

Ukg Ready Lemlist Sub-second propagation

DetectionUkg Ready notifies Stacksync of record changes through webhook events. UKG Webhooks for select events (employee.created, employee.updated, account/org changes) with HMAC signing.

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.
  • Ukg Ready: Rate limits apply over roughly a 1-minute window and return HTTP 429 when exceeded (back off / exponential retry); UKG Webhooks run on a tiered quota with a free tier around 10,000 event notifications per month and 14-day event retention.
