Shared direct mail vs. solo mailing

Both options deliver a physical postcard to the same kinds of households through the USPS. The difference is who pays for the production and mailing, and how much control and cost each business takes on.

• Cost: Solo — one business pays the full print and postage run. Shared — costs are split across advertisers.
• Reach: Both can reach the same selected households on a confirmed USPS route.
• Category exclusivity: Solo — automatic, you are the only advertiser. Shared — only when the publisher enforces one business per category.
• Design: Solo — you design (or pay to design) the whole card. Shared — design is typically coordinated and included by the publisher.
• Setup: Solo — you handle list selection, printing and mailing logistics. Shared — the publisher coordinates the campaign.
• Format: Solo — any size you choose. Shared — usually an oversized format (such as 9×12) so each offer stays readable.

A solo mailing can make sense for a business that wants complete creative control, a custom list, or a card dedicated entirely to one offer — and has the budget to cover the full production and postage cost.

Shared direct mail makes sense when you want to reach local households with a professional, readable offer but do not want to pay for an entire mailing yourself. It is especially strong for small local businesses that serve a specific community and want category exclusivity without the solo-mailing price tag.

Either way, the postcard is delivered by the USPS, and results depend on your offer, your category and customer behavior. No mailing method — shared or solo — can guarantee a specific response rate or return on investment.
