What Is a Demographic Append?
A demographic append enriches your existing customer or prospect file by attaching new attributes such as age, income, homeownership, marital status, lifestyle preferences, behavioral indicators, and more..
For B2C marketers, that means better segmentation, more relevant messaging, and stronger campaign performance across acquisition, retention, and reactivation.
Core demographic packages typically start at $0.02 per record, with expanded packages ranging from $0.02 to $0.07 depending on the fields selected.
PROVEN DATA ADVANTAGE
Large-scale consumer data coverage built to support retail, eCommerce, non-profits, automotive, home services, financial services, and direct response agencies.
Strong match performance for clean customer files so your team can activate richer audience segments faster.
Continuously refreshed data that helps your team build campaigns around more current household insight.
Flexible pricing that makes demographic enrichment practical for one-time campaigns and ongoing CRM improvement.
Cost-effective pricing designed to support both one-time projects and ongoing CRM enhancement.
Stop Marketing to Flat Records That Tell You Nothing About the Buyer
A name, postal address, and email alone do not tell you who your best customers are, what households they belong to, or how to prioritize them. Without richer customer insight, your offers get broader, your media gets less efficient, and your segmentation turns into educated guessing.
The TDG Difference: Our demographic append services help B2C brands identify the traits behind their best customers, uncover new segments worth pursuing, and build more relevant campaigns across direct mail, email, paid media, customer onboarding, retention, and win-back programs.
Our Proprietary Demographic Append Services Workflow
Our workflow is designed for marketing teams that need usable consumer insight, not oversized files loaded with low-value fields. We focus on the demographic attributes that actually improve segmentation, personalization, and performance.
Step 1 — Identity Resolution & Record Matching
We match your customer or prospect file against a large consumer database using core identifiers such as name and postal address to locate the strongest record-level and demographic connections.
Step 2 — Attribute Selection & Consumer Enrichment
We append the demographic fields most relevant to your use case, including individual and household indicators that support audience segmentation, offer strategy, lifecycle marketing, and acquisition planning.
Step 3 — Clean Output & Campaign Activation
Your enriched file is delivered in a structured format that is ready for CRM import, direct mail targeting, paid media onboarding, lookalike modeling, customer scoring, retention programs, and broader multichannel activation.

Demographic Append vs. Buying a Mailing List
A demographic append improves the customer records you already own. A mailing list gives you net-new contacts.
If your goal is to better understand, segment, and monetize your current customer or prospect database, append is usually the more efficient move.
For many B2C brands, the fastest ROI comes from enriching known customers first, then using that insight to improve acquisition targeting later.
