Why postcards still work (and what to use them for)

After two pieces on what SMS and email do well, the contrarian case: postcards do something digital channels legally can't, and for certain businesses, that's the whole game.

The opt-in wall

Every SMS marketing guide will cite 98% open rates and 90-second response times. What those guides don't mention: the TCPA requires express written consent from every recipient before a promotional text goes out. For a local HVAC company trying to reach new customers in a neighborhood where they have no existing relationships, there is no SMS list to send to. You have to build one first, which requires the relationship you're trying to initiate.

USPS Every Door Direct Mail solves this. No list required. Pick a carrier route, and every address on it receives the piece. EDDM postage runs $0.247 per piece — add printing and you're at $0.35–$0.60 all-in. For cold local acquisition at geographic scale, it's the only channel that doesn't require a prior relationship.

Where postcards hold

The data is specific about where direct mail outperforms. The 55+ demographic rates it as their preferred advertising channel at 50%. That preference widens for healthcare, financial services, and high-consideration purchases — categories where trust matters and time isn't the main variable.

Use cases where postcards reliably outperform digital cold outreach:

• •Local home services (HVAC, plumbing, electrical): Seasonal acquisition to new service areas. ANA data puts response rates at 3.16% for this vertical — unexciting until you realize the alternative is paid search at $30–$80 per click with no guarantee of intent.
• •Healthcare and dental: New-mover targeting for patient acquisition, recall campaigns for lapsed patients. Response rates run 3.38–4.09% (ANA). For new practices or new locations, EDDM is the standard acquisition play.
• •Real estate: Geographic targeting by neighborhood, investor outreach to specific property types. Each conversion is valuable enough that a 1–3% cold response rate is highly profitable.

The multichannel finding

The most useful number in this whole comparison comes from the ANA cross-channel data: combining direct mail with a digital follow-up generates 27–118% higher response than direct mail alone.

The sequence that works: the postcard goes out. Forty-eight hours later, an email that references the piece — if you have the address. A week later, an SMS if you have the number and the consent. The postcard creates awareness and dwell time (pieces stay in a home an average of 17 days). Digital channels close the loop. The businesses getting the best return from direct mail aren't running it in isolation. They're using it as the first touch in a coordinated sequence.

Your site is the landing page for all three

A postcard QR code, an email click, and an SMS link all land somewhere. A first-time visitor arriving cold from a postcard campaign has no context — they need faster load time, a cleaner conversion path, and a specific reason to call.

A site built as a brochure handles existing referrals fine. A site built to convert cold traffic from any channel — postcard, paid search, EDDM — is a different design problem.

Our Starter is purpose-built for that: a single-page, fast-loading, conversion-focused site that works as the destination for whatever channels you're running. For businesses with integrations, booking flows, or campaign-specific landing pages to wire up, Custom engagements handle the more complex builds.
