BluePoint Integra Unit List — Reverse Append Test

Overview

BluePoint ATM has access to a large Integra unit list (~300,000 locations) obtained through a GPO (Group Purchasing Organization) relationship. The list contains physical addresses and location names but is governed by an NDA that prohibits direct cold outreach (calls or emails) to the locations on it. The challenge is extracting actionable sales leads from this data without violating the NDA.

The agreed approach is a reverse append test: submit a small, anonymized excerpt of the list to a data enrichment process to see what contact information can be recovered from address data alone. Direct mail is the parallel outreach channel that sidesteps the NDA's restrictions on cold calling and email.

The List

• Source: Integra GPO supplier relationship
• Total size: ~300,000 locations
• Actionable subset: ~10,000 locations after filtering (many entries represent chains with a single decision-maker across 100+ locations)
• Available fields: Physical addresses, location names, internal codes
• Missing fields: Contact names, email addresses, phone numbers
• Constraint: NDA prohibits using the list to cold-call or cold-email Integra clients directly

Reverse Append Strategy

A reverse append uses known data points (in this case, physical addresses) to query third-party databases and recover associated contact information such as email addresses or phone numbers. Expected match rates are typically 10–15%.

Agreed Approach

1. Wade extracts a 300–400 line excerpt from the Integra list (not the full list, to minimize NDA exposure risk)
2. The excerpt is sent to Mark Hope / Asymmetric for testing against enrichment databases
3. Results determine whether the match rate justifies broader enrichment or a direct mail campaign

"Get me 200, 300, 400 from that list. Don't send me the whole list. Just get me an excerpt, maybe 300 or 400 of them and let us work on that." — Mark Hope

Why Not the Full List

Wade expressed concern about NDA liability if the full list were shared outside his organization, particularly given hacking risk. The excerpt approach limits exposure while still allowing a meaningful test of enrichment viability.

Direct Mail Alternative

If reverse append yields insufficient contact data, direct mail to the physical addresses is a viable and NDA-compliant alternative:

• Physical address outreach is not restricted by the NDA (which targets cold calls and emails)
• A BluePoint/Integra co-branded mailer may be permissible ("we could probably get away with putting an Integra logo on it")
• Direct mail pieces can include unique QR codes for recipient-level tracking (consistent with BluePoint's existing stadiums-and-arenas direct mail approach — see ^[1])
