A 3-wave postcard plus call playbook for the highest-leverage problem in chiropractic: patients who dropped off after initial pain relief and never came back.
Most lapsed chiropractic patients didn't have a bad experience. They felt better, life got busy, and the maintenance visits fell off the calendar. That's a reactivation problem, not a marketing problem — and it has a different solution.
3 waves over 8 weeks, 90-day rest cycle. Each wave escalates the offer just slightly — the goal is to remove every reason a patient might say no.
Headline: "Your Spine Misses You" · Offer: Complimentary spine check-up for returning patients.
A wellness-framed reminder, not a sales pitch. The complimentary spine check-up gets the patient back through the door without committing them to a treatment plan. The follow-up call lands 10–21 days after delivery: "Hi [Name], this is [Rep] from [Practice]. We noticed it's been a while since your last adjustment and wanted to check in." Personal, low-pressure. About 60% of all reactivations come from Wave 1.
Headline: "Free Adjustment — Welcome Back" · Offer: Free adjustment for returning patients, no insurance required.
28 days after Wave 1, only to non-responders. The offer steps up: a free actual adjustment, not just a check-up. "No insurance required" removes the biggest objection (some patients lapsed because their insurance changed). The Wave 2 call references the postcard and the offer directly: "Dr. [Name] asked me to reach out personally — we'd love to get you back in for a free adjustment." Different visual design, different QR for tracking.
Headline: "Last Chance — Free Adjustment Expires Soon" · Offer: Same free adjustment, deadline.
28 days after Wave 2. Postcard only, no call — two calls is enough; a third feels like pestering. The framing is soft urgency: "Your returning patient offer ends [date]." After Wave 3, the contact rests for 90 days before re-entering the cycle. That rest period is what keeps response rates from collapsing — over-mailing is the fastest way to train chiropractic patients to ignore your envelope.
All three waves, call timing, and copy direction are pre-configured. You set the offer language and your practice branding.
From ChiroTouch, Jane App, ChiroFusion, Eclipse, or Genesis: filter by last visit date older than 6 months, export CSV. PostKnock auto-maps the columns.
Wave 1 prints and drops into USPS within 1–2 business days. Your call queue auto-populates 10 days after delivery. Wave 2 mails 28 days later only to non-responders.
Each call has a pre-loaded warm script. Staff log outcome (booked, voicemail, wrong number, do-not-contact). Booked patients drop out automatically.
Most chiropractic practices have 250–500 patients lapsed 6+ months. Here's the math on a 400-patient run:
11:1 ROI on a single cycle — and the patients who reactivate often return to their previous care plan, multiplying the lifetime value.

PostKnock reactivation campaigns also work for
Patient reactivation is the highest-ROI chiropractic play, but PostKnock also runs new patient acquisition and seasonal wellness promos. See the full lineup on the chiropractic hub.
200–700 patients is the recommended range. Smaller than 200 and the per-card economics get hard to justify against your subscription; larger than 700 and your front desk will struggle with the call queue once Wave 1 generates booking activity. If you have 1,000+ inactive patients, split into two cohorts staggered by 30 days so the call volume is manageable.
Wave 1: a complimentary spine check-up or posture analysis — low commitment, low cost to deliver, easy to schedule. Wave 2 escalates to a free adjustment for returning patients, with "no insurance required" called out. The biggest objection from lapsed chiropractic patients is "my insurance changed" — removing that objection lifts response noticeably.
For chiropractic, 90–180 days without a visit is the right cutoff for "lapsed." Most patients on a maintenance care plan visit every 4–8 weeks; once they've missed 2–3 expected visits, they're sliding away. Earlier than 90 days and you'll annoy active patients; later than 180 and intent has cooled too far. PostKnock can run continuously, mailing each patient at the right point in their individual cycle.
ChiroTouch: Reports → Patient Reports → "Inactive Patient List" with last-visit date filter. Jane App: Reports → Patient List → filter by Last Appointment Date. ChiroFusion, Eclipse, and Genesis have similar inactive-patient queries. Export CSV with name, address, phone, and last visit date. PostKnock's import wizard auto-detects each column.
Warm and personal, never sales-y. Pre-loaded scripts open with: "Hi [Name], this is [Rep] from [Practice]. We noticed it's been a while since your last adjustment and wanted to check in." That's it — no pitch, no pressure. The patient drives the rest of the conversation. Most reactivations come from the patient saying "actually yeah, my back has been bothering me" once they're given the space to remember.
Stop hoping lapsed patients come back on their own. Run the 3-wave reactivation sequence that brings them in.
