Direct Mail Marketing and ZIP Code Targeting
Direct mail campaigns use ZIP code demographics to target audiences with precision. Here's how modern mail targeting works.
## ZIP-Based Targeting
Despite the rise of digital marketing, direct mail remains a $44 billion industry in the United States. ZIP codes are the primary targeting mechanism, allowing mailers to select audiences by geography and demographics.
## Targeting Methods
| Method | Precision | Cost per Piece |
|--------|-----------|----------------|
| Every Door Direct Mail (EDDM) | ZIP + carrier route | $0.20-0.30 |
| ZIP-targeted list | ZIP + demographics | $0.40-0.80 |
| Name-addressed | Individual + ZIP | $0.80-2.00 |
| Personalized | Individual + behavior | $2.00-5.00 |
## EDDM: Saturation Mail
USPS Every Door Direct Mail lets businesses mail to every address on a carrier route without buying a mailing list.
How it works:
1. Select target ZIP codes
2. Choose carrier routes within those ZIPs based on demographics
3. Print and deliver to USPS — they handle the rest
EDDM is popular with local businesses: restaurants, dentists, real estate agents, and home services.
## Demographics-Based Selection
Mailers select ZIP codes using Census-derived demographics:
- **Income** — Luxury brands target ZIPs with $100K+ median income
- **Age** — Medicare supplement mailers target 65+ ZIPs
- **Home ownership** — Home improvement companies target high owner-occupied ZIPs
- **Education** — Financial services target high-education ZIPs
## Postal Discounts
USPS offers significant discounts for presorted, CASS-certified, ZIP+4-coded mail:
- **Presorted First-Class** — $0.08-0.12 discount per piece
- **Marketing Mail (bulk)** — Starting at $0.202 per piece
- **ZIP+4 discount** — Additional $0.01-0.03 per piece
- **Automation** — Barcoded mail gets further discounts
## Measuring Response
Response rates by ZIP code help optimize future campaigns.
Typical direct mail response rates range from 1-5%, but well-targeted ZIP selections can double these rates. Mailers track responses by including unique URLs, QR codes, or phone numbers keyed to specific ZIP segments.
