How to Export Your Lapsed
Patients & Customers, and Mail Them

Every practice and service business has a list of people who haven't been back in a while. These step-by-step guides show you how to pull that list out of your current system as a CSV, clean it down to name, address, and phone, and import it into PostKnock to mail a postcard reactivation campaign.

The Same Three Steps, Every System

PostKnock doesn't connect to your practice-management or field-service software directly. Instead, you export a CSV once and import it: the import wizard auto-maps the columns. Each guide below walks the exact menu clicks for one system.

1

Export overdue contacts as a CSV

Run a report filtered by last-visit (or last-service) date to pull everyone overdue 12+ months, then export it to a CSV file.

2

Clean it down to name, address, and phone

Trim the export to the columns that matter for mailing. Keep PHI off the postcard. You only need where to send it.

3

Import into PostKnock & mail

Upload the CSV, pick a reactivation playbook, and launch your first postcard wave. Free to start.
