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 Mail is cheaper; First Class is faster and costs more per piece. You choose the class for each send and campaign action, starting from your account's default.
- 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.
Mailer types
| Type | Notes |
|---|---|
| 4×6 postcard | Smallest and lowest cost |
| 6×9 postcard | Mid-size, popular for real estate |
| 6×11 postcard | Large format |
| Windowed letter | Address shows through envelope window |
| Windowless letter | Address printed on envelope; full-face design |
| Notecard | 5.5x8.5 folded, premium feel, real stamp |
| MagnaCard | 6×9 magnetic, highest per-piece cost |
| Gift card | Branded gift card with QR redemption |
Standard vs. First Class
- Standard - lower cost; typically arrives in 10-20 business days from print date; no tracking; no return-to-sender.
- First Class - higher cost; typically arrives in 5-10 business days from print date; USPS tracking; return-to-sender enabled.
Standard Mail's lower price applies to US addresses, and only on paid plans: on the Free plan every piece mails First Class. Nonprofit accounts mail at their nonprofit rate instead of either class. Send Mail shows both prices on each mail piece and on its Review & Confirm step, so you can compare before you choose.
See Postage Options for guidance on when to use each, and how to set your default.
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.
Pricing a specific order
Send Mail shows a cost breakdown on its Review step, before you place the order with Submit Order & Send Now. If you send through the API, post the same request body to the matching estimate endpoint to get the order total, a US / international / extra-page breakdown, and whether your balance covers it, with nothing charged. See Estimating an Order's Cost.
