PostKnock
Postcards Get Attention. Your Callbacks Close the Deal.
PostKnock is a marketing platform built for small service businesses: dental practices, HVAC contractors, optometrists, chiropractors, veterinary clinics, and home services. It combines direct-mail postcards with automated phone follow-up in a single workflow.
Choose a pre-built industry playbook (dental recall, HVAC seasonal, lapsed-patient re-engagement, etc.), upload a contact list, and PostKnock handles printing, USPS First-Class mailing, QR tracking, and post-delivery call queues with pre-loaded scripts for your front desk.
Multi-wave campaigns sequence postcards and calls over weeks. CSV import auto-maps fields. Real-time tracking shows delivery, scans, completed calls, and revenue attribution.
Free plan available — only pay for postcards sent. Pro from $99/mo unlocks multi-wave sequencing, the full call queue, and analytics. No contracts. 30-day money-back guarantee.
