What is Thanks.io?

Thanks.io is a direct mail automation platform that sends handwritten-style postcards, letters, notecards, gift cards, and MagnaCards through a dashboard, REST API, MCP server, or integration - with QR tracking, automated campaigns, AI design (ThanksAI Studio), and AI personalization built in. Trusted by 5,000+ businesses since 2017.

The handwriting is rendered by a proprietary digital handwriting engine with realistic fonts, AI Fonts, and an optional Realism Mode - not real pens or human handwriters.

  • Automated Campaigns: Drip, birthday, anniversary, holiday, recurring, Neighbor Blast radius mailing, and evenFLOW paced sending
