EDDM vs targeted lists: when to use which.

What EDDM is

Every Door Direct Mail. The USPS sells you a guarantee that every household on a carrier route receives your piece. You pick the routes geographically; you don't pick the recipients. You don't need a mailing list, you don't need names, you don't need addresses.

Postage is the lowest available class (around $0.20 per piece in 2026) because USPS doesn't have to address-verify each piece — the carrier just drops one on every door.

What targeted lists are

You provide (or buy) a list of specific people. Names, addresses, sometimes other attributes. You mail those people specifically. USPS uses standard or first-class postage (around $0.40 to $0.55 per piece in 2026).

Targeted lists let you mail your existing customer base, leads who downloaded a guide, prospects matching demographic criteria you can't filter on at the route level.

When to use EDDM

• You sell to households (everyone on the street is a candidate)
• The offer is broad enough to convert ANY household reading it
• You want to dominate a specific neighborhood's awareness
• You don't have a customer list yet
• Cost-per-piece matters more than precision targeting

Examples: pizzerias, dental practices, HVAC, lawn care, real estate agents, salons, gyms, urgent care.

When to use targeted lists

• You sell to a specific demographic (age, income, life stage) that doesn't tile cleanly to ZIP boundaries
• You're remarketing to existing customers (house list)
• The offer requires the recipient to already be a known prospect (lead nurture)
• The cost per acquisition justifies higher per-piece postage

Examples: financial advisors targeting a $250K+ income bracket, nonprofits remailing past donors, B2B campaigns mailing named decision-makers.

What most businesses get wrong

The mistake isn't picking the wrong format; it's mixing them up. They run "EDDM" but apply demographic filters to it (which means they're paying first-class postage for an EDDM-style mailing). Or they mail their house list every six months as if it were EDDM (which means they're getting EDDM response rates from a list that should yield 5× more).

Pick the format that matches the campaign. Use both at different points in your funnel.
