Per-Piece Rates
Every mailer you send incurs a per-piece charge that covers design, printing, and postage - all bundled into a single rate. No separate postage invoices.
Per-piece rates vary based on three factors:
- Mailer type - postcards, letters, Notecards, MagnaCards, and gift cards are each priced differently.
- Postage class - Standard is cheaper; First Class is faster and costs more per piece.
- Your plan tier - higher tiers (Business, Professional) unlock lower per-piece rates.
Current rates are always at thanks.io/pricing - do not rely on cached numbers.

Multi-page letters
Both windowed and windowless letters support multi-page sends. The first physical page is included in the base per-piece price. Each additional physical page adds $0.20 per piece. A sheet printed front/back counts as one physical page, not two.
