Thanks.io

Direct mail automation platform for sending personalized postcards, letters, notecards, QR

Visit Thanks.io

Thanks.io is a direct mail automation platform that lets businesses send handwritten-style postcards, letters, notecards, and gift cards through a dashboard, API, or integrations. It addresses the logistics of direct mail by handling printing, handwriting rendering, and postage in one workflow, with QR code tracking to monitor scans and delivery.

Core capabilities include a REST API with OAuth2 authentication, an MCP server, webhooks, and integrations with Zapier, Make, Pipedream, HubSpot, and other CRM and e-commerce platforms. Features cover AI-generated campaign creation through AI Studio, dynamic personalization, multi-touch drip campaigns, gift card sending, neighbor targeting, and QR code tracking with notifications. A separate Cart Mailer product automates abandoned-cart postcards for e-commerce stores, with identity resolution, AI-generated creative, and attribution reporting.

Thanks.io is aimed at developers embedding mail into products, individual senders managing campaigns through the dashboard or CSV upload, and teams or agencies handling higher volumes. Pricing is packaged as a pay-as-you-go plan with no monthly subscription, plus Business and Professional subscription tiers offering lower per-piece rates; yearly plans are also available. Gift card sending requires Business or higher. Per-piece pricing includes postage, with no minimums or commitments.
