Real Cost Breakdown
Hidden Costs
- Per-piece print and postage costs on top of any platform fee (starting at $0.582-$0.872 per postcard depending on tier)
- Address verification costs extra: $0.009-$0.05 per US verification depending on plan
- Startup and Growth plan subscription prices are not publicly disclosed
- International address verifications cost $0.055-$0.07 each
Cost Saving Tips
- Use the free Developer plan for testing before committing to a paid tier
- Higher tiers offer significantly lower per-piece costs — Growth postcards are 33% cheaper than Developer
- Batch address verification is cheaper per-unit than real-time on higher plans
Free to start with 500 mailings, but costs scale with volume through per-piece charges and undisclosed platform fees on mid-tier plans — best value comes at high volume on Growth or Enterprise.

Best For
Marketing and ops teams sending high-volume, compliance-sensitive direct mail at scale
Who Should NOT Use This
- Small businesses sending fewer than 100 pieces of mail per year — The per-piece costs and platform complexity are overkill when you can simply print and mail manually or use a local print shop.
- Companies that need primarily international direct mail — Lob's Print Delivery Network and Postal IQ routing are built around USPS and US-based delivery infrastructure.
- Non-technical teams without developer resources on the free plan — The Developer plan is API-focused with no no-code integrations; you need to upgrade to Startup or above for no-code access.
- Organizations needing HIPAA compliance on a budget — HIPAA-compliant mailings require the Enterprise plan, which has custom (likely higher) pricing.
Competitive Position
Lob's combination of Postal IQ routing intelligence and a nationwide Print Delivery Network that produces mail near its destination is unmatched for speed and cost optimization in automated direct mail.
When to Choose Lob
- You need to send high-volume direct mail programmatically via API
- Delivery speed matters — Lob's print-near-destination network reduces transit time
- You operate in healthcare or finance and need HIPAA/compliance-ready direct mail
- You want to integrate direct mail triggers into existing marketing automation workflows
When to Look Elsewhere
- You only need occasional one-off mailings and don't want to learn an API
- Your direct mail is primarily international rather than US-based
- You need custom print formats beyond postcards, letters, and standard mailers
- You want a full-service agency to handle design, strategy, and fulfillment end-to-end
