PostKnock is a direct mail marketing SaaS platform that combines USPS postcard campaigns with systematic front-desk follow-up calls. It is built for small service businesses such as dental, optometry, chiropractic, veterinary, med spa, HVAC, plumbing, landscaping, and pest control practices. Users pick a pre-built industry playbook, import a CSV of contacts, and launch coordinated multi-wave campaigns where postcards warm the lead and a prioritized call queue (with scripts, timing, and outcome tracking) helps staff close the deal. Features include single- and multi-wave postcard sequencing, staggered scheduling, QR and URL tracking, delivery tracking, an in-browser postcard designer, industry templates, real-time notifications, and advanced analytics. Pricing starts free with postcards from $1.05 each, and the Pro plan is $99/month (or $799/year) with postcards from $0.79 each.

How much do postcards cost to send?
What is postcard marketing with follow-up calls?
PostKnock combines direct mail postcards with automated phone follow-up. You send a postcard, and a few days after delivery, your team gets a call queue with the right script for each contact. The postcard gets attention, and the callback closes the deal.
What industries does PostKnock support?
PostKnock has ready-made campaign playbooks for healthcare-style practices (dental, optometry, chiropractic, med spas, veterinary clinics) and home-services contractors (HVAC, plumbing, pest control, landscaping). It works for any local service business that wants to reach customers by mail and follow up with phone calls.
What is included in the per-card price?
Every per-card price includes full-color printing on both sides, USPS First-Class postage, and delivery tracking. There are no separate charges for postage, printing, or tracking. What you see is what you pay.
Can I cancel Pro at any time?
Yes. Pro is month-to-month with no long-term commitment. You can cancel anytime and you keep access through the end of your billing period. If you choose annual billing ($799/year), you get a 30-day money-back guarantee. After cancellation your account reverts to the Free plan and your contacts and campaign history stay intact.
How does PostKnock compare to other direct mail tools?
Most direct mail tools only send postcards. PostKnock adds phone follow-up calls, industry-specific playbooks, and a built-in call queue with scripts and timing. The platform is designed for small service businesses that want a coordinated postcard-plus-callback workflow rather than just batch mail.
