Every overdue annual exam is a glasses or contacts sale walking out the door. PostKnock mails reactivation postcards to your lapsed 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 already trusts your practice and quietly slipped off the recall list. Reactivation postcards plus a call are how you catch them before they buy their next pair of glasses online or down the street.
Patients past their yearly comprehensive eye exam who never pre-booked at checkout. The recall list grows every month it isn't worked — and so does their next Rx change.
A glasses or contact-lens Rx that lapsed means they can't reorder lenses without coming back. That expiration date is a built-in reason to reach out before they go elsewhere.
The patient who got the exam but bought frames or contacts somewhere cheaper. A reactivation card with an optical offer brings the capture opportunity back into your shop.
VSP, EyeMed, Davis and similar plans reset every year. Patients with an unused exam-and-materials allowance are prime to reactivate — a timed Q4 card gives them a deadline.
Patients with flexible-spending funds to use before year-end will spend them on glasses, sunglasses, or a backup pair — if someone reminds them in time.
One parent skips a year and the kids' annual exams lapse with them. Reactivating one household can rebook the whole family before the school year starts.
Recall texts and "you're due" emails 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 one-two punch is what PostKnock is built for.
A multi-touch wave sequence built for overdue eye-care 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 upgrade, frames credit, or "let's get you back on the schedule"). QR code to online booking.
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 — your prescription is due to renew and we have openings this week." Staff logs the outcome in one click.
A different design for everyone who hasn't rebooked. Lead with vision benefits resetting, FSA dollars expiring, or a limited-time complete-pair 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 recall 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 book today. These are common, eye-care-appropriate angles you can drop into the postcard offer field — pick what fits your patient mix, your optical, 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.

In RevolutionEHR, Crystal PM, Compulink, Eyefinity, My Vision Express — or any system — run a report for patients with no exam in 12+ months (or your own cutoff, including expiring prescriptions) 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-exam columns. Segment overdue annual exams vs. expiring contact-lens Rx vs. unused-benefits patients if you want different offers per group.
Choose the wave sequence, set your eye-care offer, and design the postcard in the Design Studio. Add a QR code that points to your online scheduler so patients can self-book their exam.
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 exam 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, optical capture, and insurance 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 their recall exam — commonly 12+ months since their last comprehensive eye exam — or once their glasses or contact-lens prescription has expired with no rebooked visit. You set the cutoff when you pull the list from your EHR or 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 eye-care 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. RevolutionEHR, Crystal PM, Compulink, Eyefinity, My Vision Express and most other eye-care systems let you run a recall or inactive-patient report and export it as a CSV. Filter by last exam date or prescription expiration to find lapsed patients, then import the CSV into PostKnock — the wizard auto-maps name, address, phone, and last-exam 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 frames or lens credit with a booked exam, a complimentary exam upgrade, or a "use your vision benefits before year-end" nudge. Contact-lens wearers respond well to an expiring-Rx renewal reminder. Always check your state optometry board's advertising rules — you write the offer copy, PostKnock prints and mails it.
Two windows work especially well for eye care: Q4, when vision benefits and FSA / HSA dollars are about to reset or expire, and late summer for back-to-school family exams. That said, the most effective reactivation campaign is the one that runs continuously — pull your overdue list monthly and keep the recall pipeline moving rather than waiting for one big annual push.
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 exam, so most practices use it.
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.
PostKnock keeps PHI off the postcard by default and your export only needs name, address, and contact info — no diagnoses or prescription values.

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.
