Win back the customers you already earned. Edit a headline, offer, call-to-action and QR code, then mail it — with optional front-desk follow-up calls. Start on the free plan, no credit card required.
Start Free — No Credit CardLapsed customers are the cheapest list you'll ever mail. They already know your name, they've paid you before, and they just drifted. A physical postcard lands on the counter where a forgotten email never will — and pairing it with a friendly follow-up call turns "I've been meaning to" into a booked appointment.
You already have these names, addresses, and visit history. Export them from your existing system as a CSV and import the file into PostKnock — the import wizard auto-maps the columns.
Industry studies (ANA Response Rate Report) typically report direct-mail response in the low single digits, with house lists at the higher end of that range — well above typical email. Treat any figure as an estimate, not a promise.
A postcard plus a phone call from your front desk a few days later (the built-in Call Queue, a Pro feature) consistently outperforms either channel alone. PostKnock sequences both for you.
Response and ROI vary widely by industry, offer, and list quality. Figures above are industry-standard ranges, not PostKnock results.
Each is a 4×6 front design with an editable headline, offer, call-to-action, and a real QR code (link it to your booking page or phone number). Open any one in the Design Studio and make it yours — for free.

Reactivation resources & industry templates
Yes. Editing any template in the PostKnock Design Studio is free, with no credit card required. You only pay per piece when you actually mail — from $1.05 per 4×6 card on the Free plan and from $0.79 on Pro. Printing and USPS First-Class postage are included in that per-piece price.
A warm, personal headline ("We miss you"), a specific and time-bound offer, your business name and phone number, and an easy next step — a QR code to your booking page works well. Long-lapsed customers respond best to a concrete, high-value offer rather than a generic reminder. Every field in these templates is editable.
Results vary by industry, offer, and list quality, so treat any number as an estimate. Industry studies (such as the ANA Response Rate Report) typically report direct-mail response in the low single digits, with house lists — like your own lapsed customers — landing toward the higher end of that range. Pairing the postcard with a follow-up phone call generally lifts response further.
PostKnock includes pre-built playbooks and starting designs for 50+ industries — dental, HVAC, hair and nail salons, optometry, med spa, veterinary, chiropractic, plumbing, landscaping, and many more. The three above are examples; you can adapt any template to your business in the Design Studio.
Export your inactive customers from whatever system you already use — filter by last visit or purchase date — as a CSV file, then upload that CSV to PostKnock. The import wizard auto-maps name, address, and phone columns. PostKnock does not connect to your CRM or practice software directly; the supported path is CSV export and import.
Yes, on the Pro plan. After a postcard is delivered, the built-in Call Queue populates so your front desk can work a daily list of follow-up calls using per-wave scripts. You can also run multi-touch wave sequences (up to 5 waves) so non-responders automatically advance to the next touch.
PostKnock supports three sizes: 4×6, 6×9, and 6×11. The templates above are shown at 4×6, the most common and lowest-cost option. You can switch sizes in the Design Studio, and EDDM-style saturation mailing is available when you want to blanket a neighborhood instead of a named list.
Customize a reactivation template free, then mail it — with optional follow-up calls.
