# Sendpaper for Codex, Muse Code and Claude

Mail real postcards and letters from your agent. The agent drafts the mail and gets back a print preview and a Stripe checkout link. Nothing is mailed until it's paid, by you or by your agent with your approval, and a person reviews every piece before it's printed and sent via USPS First-Class (US addresses only).

Products: postcards (4×6, 6×9, 6×11; headline, photo, photo + caption or collage fronts), letters you write or your own PDF (up to 6 pages, color optional), USPS Certified Mail with tracking and an optional return receipt, and express delivery (USPS Priority Mail). Printing and postage are included, and first orders get a discount when a promotion is running. Current prices: [sendmypaper.com/#pricing](https://sendmypaper.com/#pricing), or ask your agent (it calls `get_pricing`).
