Why teams connect Klaviyo and Smartrecruiters

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

Each tool in Klaviyo 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. Smartrecruiters 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 Profiles, Lists, Segments, Events in Klaviyo with Interviews, Offers, Users, Approvals in Smartrecruiters bi-directionally and in real time. A person added, moved, or offboarded in Smartrecruiters creates or updates the matching user in Klaviyo within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Klaviyo captures details of its own, such as a corrected contact or a login identity, those can flow back to Smartrecruiters 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 customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • 02 Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • 03 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update hiring status, tags, and custom fields in SQL while recruiters keep working in SmartRecruiters.
  • 04 Write enriched or sourced Candidates from external sourcing tools into SmartRecruiters and keep contact fields refreshed as data changes.

Common sync patterns

Onboarding: access ready on day one

A new hire recorded in Smartrecruiters creates the matching user in Klaviyo with the right team and manager already set, so people can start working without waiting on a provisioning ticket.

Offboarding: no standing access after a departure

When someone is marked as leaving in Smartrecruiters, the matching account in Klaviyo 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.

Rate-limit considerations

  • Klaviyo: Per-endpoint burst and steady rate limits apply.
  • Smartrecruiters: Per API credential: most endpoints allow up to 10 requests/sec (job publication and offer documents 2/sec), plus a concurrency limiter of up to 8 simultaneous requests (GET /candidates capped at 1). Exceeding returns 429; responses carry X-RateLimit-Limit/Remaining and concurrent-limit headers.
