Your hygiene chairs only earn when they're full. PostKnock mails reactivation postcards to your overdue patients — then puts each one in your front desk's call queue so a real person follows up.

"Lapsed" isn't one problem — it's several. Each one is a patient who was already yours and quietly fell off the schedule. Reactivation postcards plus a call are how you catch them before they pick a new office.
Patients overdue for their 6-month cleaning who never got re-scheduled at checkout. The recall list grows every month it isn't worked.
12+ months since the last prophy or perio maintenance. The longer the gap, the more treatment they need — and the easier it is for them to drift to another practice.
The patient who cancelled and never rebooked, or no-showed twice and stopped answering reminder texts. A postcard reaches them where notifications don't.
Diagnosed but never booked — the crown, the night guard, the deep cleaning that sits in the chart unscheduled.
Patients with benefits resetting at year-end who haven't used their cleanings. A timed Q4 postcard is a reason to call back.
One parent reschedules and the kids' cleanings quietly lapse too. Reactivating one address can rebook three chairs.
Reminder texts get muted. A reactivation postcard physically lands in the mailbox — then, a few days later, a familiar voice from the front desk closes the loop. That one-two punch is what PostKnock is built for.
A multi-touch wave sequence built for overdue dental 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 (complimentary exam, hygiene discount, or "let's get you back on the books"). 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. ___ asked me to reach out — we have a couple of openings this week." Staff logs the outcome in one click.
A different design for everyone who hasn't rebooked. Lead with insurance benefits resetting, or a limited-time hygiene offer with a real deadline.
Last call attempt for non-responders, paired with a low-key "we'd hate to lose you" 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, dental-appropriate angles you can drop into the postcard offer field — pick what fits your patient mix and your state's advertising rules.
Offers are illustrative. You set the offer copy; PostKnock prints and mails the card and queues the follow-up call.
Design it in the in-app Design Studio in your practice'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 Dentrix, Eaglesoft, Open Dental, Curve, Denticon — or any system — run a report for patients with no visit in 12+ months (or your own cutoff) and export it as a CSV. PostKnock doesn't connect to your PMS; 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 overdue hygiene vs. long-lapsed vs. unscheduled treatment if you want different offers per group.
Choose the wave sequence, set your dental 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 practice pulls 500 lapsed patients (no visit in 12+ months) 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 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.

Most practices treat a patient as lapsed once they're overdue for recall — commonly 12+ months since their last cleaning or exam — or after a string of cancels and no-shows with no rebooked appointment. You set the cutoff when you pull the list from your practice management system; PostKnock just mails to whoever is on your CSV.
Recall reminders are texts and emails the patient may have already tuned 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. Dentrix, Eaglesoft, Open Dental, Curve, Denticon and most other systems let you run an inactive-patient report and export it as a CSV. Filter by last visit date to find patients overdue 12+ months, then import the CSV into PostKnock — the wizard auto-maps name, address, phone, and last-visit columns. PostKnock does not integrate directly with your PMS; you export the file and import it.
One clear offer with a reason to act now works best: a complimentary exam with a scheduled cleaning, a hygiene discount, or a "use your benefits before year-end" nudge. Long-lapsed patients (2+ years) tend to respond better to a higher-value offer than a generic "we miss you." Always check your state dental board's advertising rules — you write the offer copy, PostKnock prints and mails it.
Most practices 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 appointment, so most practices use it.
Long-lapsed patients respond best to a specific, high-value offer — like a free comprehensive exam to re-establish their records — rather than a vague greeting. Pair it with a wave sequence and a follow-up call. 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 long-dormant list to come back.
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.
