Most patients don't quit — they feel better and drift off the schedule. PostKnock mails reactivation postcards to your dormant patients, then drops each one into your front desk's call queue so a real person follows up.

In chiropractic, "lapsed" rarely means unhappy. The pain resolves, the care plan ends, life gets busy — and a patient who was already yours quietly disappears. Reactivation postcards plus a call are how you reach them before the next flare-up sends them somewhere else.
The patient who came three times a week during the acute phase, felt 80% better, and stopped — before reaching the stability and wellness phases their care plan called for.
A patient who paid for a 24-visit corrective plan, completed 14, and ghosted the rest. The remaining visits are revenue you've already earned the right to — if you re-engage them.
Wellness and maintenance patients who were on a monthly or quarterly cadence and slipped off. Without a recall workflow, nobody notices until the schedule has a hole in it.
The patient who cancelled mid-plan and never rebooked, or no-showed twice and stopped answering reminder texts. A postcard reaches the mailbox where the notifications don't land.
Back pain has a calendar — New Year posture resolutions, back-to-school backpacks, ski and golf season, the snow-shoveling and yard-work months. A timed card meets the ache at the right moment.
Patients with chiropractic benefits or HSA/FSA dollars that reset at year-end and went unused. A Q4 reactivation card gives them a concrete reason to call back now.
Reminder texts get muted. A reactivation postcard physically lands in the mailbox — then, a few days later, a familiar voice from your front desk closes the loop. That postcard-plus-call one-two punch is what PostKnock is built for.
A multi-touch wave sequence built for dormant chiropractic patients. Postcards mail on schedule; non-responders flow into the Call Queue and roll forward to the next wave automatically.
Warm, personal tone with the patient's name auto-filled. One offer (a re-exam, a spinal/posture check, or "let's pick your plan back up"). QR code to online scheduling.
3–5 days after the card lands, the patient appears in your Call Queue with a pre-loaded script: "Dr. ___ wanted me to check in — how's the lower back been since your last adjustment?" Staff logs the outcome in one click.
A different design for everyone who hasn't rebooked. Lead with a seasonal hook (New Year posture reset, back-to-school backpack check) or a "finish your care plan" message with a real deadline.
Last call attempt for non-responders, paired with a low-key "we'd love to see you back" postcard. Then the segment rests before you recycle it next cycle.
Wave count, timing, and call cadence are yours to set — PostKnock supports up to 5 waves. The phone-call waves use the built-in Call Queue, a Pro feature.
A reactivation card needs a reason to call back today. These are common, chiropractic-appropriate angles you can drop into the postcard offer field — pick what fits your patient mix and your state board's advertising rules.
Offers are illustrative. You set the offer copy; PostKnock prints and mails the card and queues the follow-up call. Free or discounted-exam offers are regulated differently by state — check your board.
Design it in the in-app Design Studio in your clinic's colors. Four starting styles — same offer and same call follow-up behind each, so pick the look that fits your brand.

Available in 4×6, 6×9, and 6×11. All-in pricing includes printing and USPS First-Class postage.
In ChiroTouch, Jane, Genesis, Platinum System, ChiroFusion — or any system — run a report for patients with no visit in your chosen window (say 6+ or 12+ months, or an incomplete care plan) and export it as a CSV. PostKnock doesn't connect to your EHR; you export the file, then import it.
Drop in the export and the import wizard auto-maps name, address, phone, and last-visit columns. Segment dropped care plans vs. lapsed maintenance vs. long-inactive if you want different offers per group.
Choose the wave sequence, set your chiropractic offer, and design the postcard in the Design Studio. Add a QR code that points to your online scheduler so patients can self-book.
Cards print and ship via USPS First-Class automatically. A few days after delivery, every patient who hasn't rebooked drops into the Call Queue. Non-responders advance to the next wave on their own.
Staff calls down the queue with the pre-loaded script and logs each outcome. QR scans are tracked so you can see which cards drove online bookings versus calls.
Say a clinic pulls 400 inactive patients (no visit in 12+ months or an incomplete care plan) and runs a 3-wave reactivation sequence with call follow-up. Here's the transparent math — the inputs are illustrative, not a guarantee:
Response and reactivation rates are industry-typical ranges, not PostKnock results. Per-patient value depends on your fee schedule, visit cadence, and case mix. Add a Pro subscription ($99/mo) on top of per-piece cost if you want the Call Queue and multi-wave sequencing.
Free to explore — you only pay when you're ready to send. Pay from your wallet per piece.

Most clinics treat a patient as lapsed once they've dropped off the schedule — commonly after they plateau and stop mid-care-plan, miss their maintenance cadence, or go 6 to 12+ months with no visit. You set the cutoff when you pull the list from your EHR; PostKnock just mails to whoever is on your CSV.
Reminders are texts and emails for patients who already have an appointment — and lapsed patients have tuned them out. A reactivation postcard physically arrives in the mailbox with a specific offer, and on Pro the patient then drops into your Call Queue so the front desk follows up by phone. It's the postcard-plus-call one-two punch, not another notification.
Yes. ChiroTouch, Jane, Genesis, Platinum System, ChiroFusion and most other chiropractic EHRs let you run an inactive-patient or last-visit report and export it as a CSV. Filter by last visit date or incomplete care plan, then import the CSV into PostKnock — the wizard auto-maps name, address, phone, and last-visit columns. PostKnock does not integrate directly with your EHR; you export the file and import it.
One clear offer with a reason to act now works best: a complimentary re-exam or progress review, a "finish your care plan" check-in, or a seasonal hook like a New Year posture reset or back-to-school backpack check. Long-inactive patients tend to respond to a higher-value consult over a generic "we miss you." Always check your state chiropractic board's advertising rules — free or discounted-exam offers are regulated differently by state. You write the offer copy; PostKnock prints and mails it.
Most clinics run 3 to 4 waves over several weeks, mixing postcards with one or two call attempts for non-responders. PostKnock supports multi-touch wave sequences of up to 5 waves; you control the timing and which waves are postcards versus calls. A single touch rarely rebooks — the follow-up is what closes it.
You can mail postcards on the Free plan with no calls at all. The built-in Call Queue — which puts each lapsed patient in front of your front desk with a pre-loaded script after the card lands — is a Pro feature. For reactivation specifically, the call is usually what turns interest into a booked visit, so most clinics use it.
Segment the patients who stopped mid-plan and lead with a "let's finish what we started" message — a complimentary re-exam or progress review to re-baseline, paired with a follow-up call referencing where they left off. Pair that with a wave sequence. Industry studies typically report direct-mail response in the low-single-digit-percent range on a house list, so expect a meaningful but modest share of a dormant list to come back.
Back pain follows the calendar, so time cards to the moment patients feel it: New Year posture and wellness resolutions, back-to-school backpack season, the start of ski, golf, or yard-work season, and Q4 when chiropractic benefits and HSA/FSA dollars are about to reset. PostKnock lets you schedule waves so the right card lands at the right moment.
You pay per piece from your wallet: from $1.05 per 4×6 card on the Free plan, dropping to $0.79 on Pro, with printing and USPS First-Class postage included. Pro is $99/mo (or $799/yr) and adds the Call Queue and multi-wave sequencing. No setup fees, no minimums, no contracts — you only pay for what you send.

Postcards that get attention. Callbacks that close the deal. Start free — you only pay when you send.
Start Free — No Credit Card1 Response and reactivation figures are industry-typical ranges, not PostKnock results. House-list direct-mail response is commonly reported in the low-single-digit-to-high-single-digit percent range — e.g. ANA (Association of National Advertisers), Response Rate Report. Your results depend on your list, offer, and follow-up.
