Heads up: no Eaglesoft integration. PostKnock does not connect to, sync with, or read from Eaglesoft. This is a manual export-then-import workflow. Eaglesoft is a Patterson Dental product and is not affiliated with PostKnock.

How we checked these steps. These steps come from Patterson’s own Eaglesoft support answers (Patterson Support Center). Steps we could not confirm there are marked. Last checked September 2026. Software menus change between versions; if yours looks different, the sources below link to the vendor’s own help pages.

What you’ll need

The Step-by-Step Export

1

Open Reports › Patients › Patient Master

Go to Reports, open the Patients tab, scroll to Patient Master, and click Process.

Sources: Patterson Support answers 11259 and 20457.

2

Filter to active patients with an old Last Visit Date

In the Patient Filter, set Marked As to Patient (the other options are Responsible Party and Policy Holder) and Status to Active, unchecking Inactive. Click into the Last Visit Date box and enter a range that ends 12 or more months ago.

Sources: Patterson Support answers 20457 and 11259.

3

Preview, then right-click › Save Data As

Click Preview Report. Right-click anywhere in the preview and choose Save Data As. Pick a folder, name the file, and choose *.xls (Microsoft Excel) or *.csv (Comma Delimited File), then click Save.

Patterson warns the saved data can contain more columns than the preview shows, so expect to delete some.

Sources: Patterson Support answers 11259 (marked for all Eaglesoft versions) and 39174.

4

Check the columns in the file

Open the file and confirm it has patient name, street, city, state, ZIP, and a phone number. Delete anything clinical or financial.

We could not find a Patterson article that lists the exact columns in the Patient Master export, so look at your own file before importing.

5

Import the file into PostKnock

In PostKnock, go to Contacts › Import and upload the file as it came out (CSV or Excel both work). Confirm the column mapping, then read the review screen: it tells you how many rows are mailable and why any are not, before anything is saved.

Which columns to keep

Keep only what a postcard and a follow-up call need:

PostKnock needs a name (or a company name) and a complete U.S. mailing address on every row. Phone is what your team uses for call follow-up on Pro. Everything else is optional, so leave clinical, balance, and notes columns out of the file.

Common gotchas

After the export: import, then mail and call

  1. In PostKnock, open Contacts › Import and upload the CSV or Excel file. The importer auto-detects your columns and shows a mapping table (your column, what it maps to, a sample value). A whole address in one cell can map to Full mailing address (one column).
  2. Check the review screen before anything is saved. It shows how many rows are mailable, how many are missing an address, and how many duplicate an existing contact, and it previews rows as the address block that would print.
  3. Pick a playbook for your industry, customize the card in the Design Studio (4×6, 6×9, or 6×11), and launch. Postcards print and mail USPS First-Class. On Pro, a Call Queue lists who to phone after the cards land.

Frequently Asked Questions

Does PostKnock integrate directly with Eaglesoft?▼

No. There is no Eaglesoft integration or sync. You save the report data from Eaglesoft as Excel or CSV and import it into PostKnock.

Which Eaglesoft report should I use for lapsed patients?▼

The Patient Master report under Reports, Patients tab, filtered to Marked As Patient, Status Active, and a Last Visit Date range ending 12 or more months ago.

Excel or CSV?▼

Either. Eaglesoft’s Save Data As offers both, and PostKnock imports both.

Is there a report with just email addresses?▼

Yes, Patterson documents a Patients With Email Addresses report (versions 14 and above). For postcards you need mailing addresses, so Patient Master is the better starting point.

Is exporting patient data to a mailer allowed under HIPAA?▼

PostKnock is built to be HIPAA-aware, not HIPAA-certified: we keep PHI off the postcard by default, we don’t sign Business Associate Agreements, and we don’t ask you to upload clinical data. Export only names, addresses, and phone numbers. For your specific situation, follow your practice’s policies and consult your compliance advisor.

Turn that export into booked appointments

Import your file, pick a playbook, and mail your first wave. Free to start.
