About

PostKnock is a marketing platform 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-code 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/month unlocks multi-wave sequencing, the full call queue, and analytics. No contracts. 30-day money-back guarantee.

About

Postmarkr is a browser-based print-and-mail service for sending USPS First-Class letters. Upload a finished PDF or use a reusable letter template, add one recipient or import a CSV for a batch, verify recipient addresses, review the true-to-print preview and exact price, and submit. Postmarkr handles printing, postage, and mailing. The dashboard shows processing history, mail-stream status, and USPS scan updates when available. Postmarkr is built for small businesses, professional-services firms, agencies, founders, operators, and administrative teams that send routine business letters. Pay per piece with no subscription or monthly minimum.
