INTEGRATIONS
PostKnock Integrations
PostKnock works with what you already use. CSV import covers the most common cases today; Zapier, native CRM connectors, and deep practice-management integrations ship as customer demand decides priority. Cast your vote below.
Don't see your tool? Until a deep integration ships, every system here can feed PostKnock through CSV import (auto-mapped column detection). Vote on the integrations you'd actually use and we'll prioritize accordingly.
Universal Automation & CRM
CSV import covers the most common cases today; Zapier and native CRM connectors are on the roadmap.
Universal connector. Auto-mapped column detection for contact lists. Re-import on any cadence. Works with every system on this page.
Planned: inbound webhook for "contact added" — auto-enroll new contacts in any playbook from 6,000+ source apps.
Planned: invoice export and tax-line reconciliation. Today, Stripe receipts and PostKnock's billing CSV are easy to import manually.
Subscription billing for Pro plans — handled by us, no setup needed.
Two-way contact sync, list-based campaign triggers, lifecycle-stage filters.
Audience & segment sync — add postcards as a step in your existing email automations.
Lead/Contact sync, Campaign Member status, Process Builder triggers.
List sync and "lapsed subscriber" trigger for postcard reactivation.
Practice Management — Healthcare
Most PMS systems do email/SMS poorly and have no postcard or phone-followup module. PostKnock fills that gap. Today, lapsed-patient pulls work via CSV export. Native sync below is prioritized by votes.
Henry Schein's flagship dental PMS. Sync inactive patients overdue 6/12/24+ months.
Open-source dental PMS with a documented HL7/MySQL backend — deepest sync potential.
Patterson Dental PMS. Inactive-patient list export and birthday triggers planned.
Top chiropractic EHR/PMS. Lapsed-patient and re-evaluation campaigns.
Audiology PMS — annual hearing test reminders driven by exam dates.
Field Service & Trades
Service software handles dispatch and invoicing. PostKnock fills the gap on win-back and seasonal-tune-up postcards plus phone follow-up.
HVAC/plumbing/electrical industry leader. Equipment-age and last-service triggers.
Customer list and "last service date" sync for tune-up reminders.
Client and job sync, recurring-service reminders for landscaping/cleaning/pest.
Personal & Fitness
Studio-management platforms handle bookings; PostKnock handles the lapsed-member win-back at a price that doesn't crush your CAC.
Industry standard for yoga/fitness/wellness. Lapsed-member & intro-offer triggers.
Salons, spas, and fitness booking. Last-visit and birthday-month triggers.
Convert ClassPass trial users into direct studio members through targeted postcards.

Shop-management software with VIN history. Mileage-based oil change & brake reminders.
Collision repair management. Post-repair check-in cards and review requests.
Independent auto-repair shop POS & CRM. Customer-vehicle history sync.
Real Estate & Finance
Just-sold and farm-area campaigns are postcard-native workflows. The CRMs you use to manage leads sync into PostKnock for follow-up timing.
Real estate CRM. Auto-trigger just-sold and just-listed postcards by ZIP.
Don't want to wait?
Every system listed above can feed PostKnock today via CSV import:
- CSV import. Export your patient/customer/client list and upload. PostKnock auto-maps the columns — no template gymnastics. Re-export and re-import on whatever cadence suits you.
CSV import preserves UTM tags, custom fields, and segment membership. Native integrations save you the export step and unlock advanced triggers (treatment-due-date, mileage threshold, etc.) — vote for the connector you want first.
