Two direct mail platforms built for different jobs: Lob is an API-first print and mail network for high-volume operational mail. Thanks.io is a personalization and automation platform for handwriting-style, QR-tracked marketing mail with no minimums.
Facts only, with a source link for every vendor claim. Lob figures verified September 18, 2026.
Neither platform is better in the abstract. Lob is the stronger fit for developer teams mailing large volumes of transactional documents and checks under a compliance program. Thanks.io is the stronger fit for marketers, agencies, and small teams who want each piece personalized, trackable by QR code, and sent through campaigns, integrations, or an AI agent — starting at zero monthly cost with no minimums.

At the paid tiers, Lob's listed postcard rate is a few cents lower than Thanks.io's. Reaching those rates means paying Lob's monthly platform fee and fitting an annual mailing tier, and Lob's postcards are standard printed pieces. Thanks.io's per-piece price includes the handwriting-style rendering, a unique QR code per recipient, and personalization, and its Pay as you go plan has no monthly fee at all. Which comes out cheaper depends on your monthly volume and on whether you would otherwise pay for personalization and tracking separately.
Marketers, agencies, real estate teams, e-commerce brands, and small businesses that treat mail as a response channel. Every piece can carry handwriting-style text, the recipient's own details, and a unique QR code, so you know who scanned and can act on it automatically. Sends run from the dashboard, the REST API, native CRM integrations such as HubSpot, 500+ apps through Zapier and n8n, or an AI agent connected over the MCP server. Trusted by 5,000+ businesses since 2017.
