Sendpaper prints and mails real postcards, letters and USPS Certified Mail with tracking to US addresses. Ask Muse to mail a thank-you or birthday postcard, a letter you write, your own PDF, or the same card to up to 25 people. Muse shows you the exact print preview and a Stripe checkout link; nothing is mailed until you pay. A person reviews every piece before it prints. Senders can be anywhere; recipients must be in the US. No account or sign-in needed.

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Sendpaper to help me. It is a free service with an MCP server at https://sendmypaper.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
