Mail a letter or certified letter with Postedly

Print and mail one finished PDF to one US address, as a regular letter or as certified (USPS Certified Mail with a tracking number). Postedly adds a separate address page. The user reviews the final proof and total on a private Postedly page, approves, and pays on hosted Stripe Checkout.

Do not use this skill when:

• The user only wants a letter drafted or edited. Write it, and do not quote or upload anything unless they ask to mail it.
• The user wants to email a PDF, or send a handwritten card (use the handwritten card skill) or a postcard (use the postcard skill).
• Either address is outside the 50 states and DC. International addresses and US territories are not supported.
• The user wants a physical object made and shipped (3D print beta). See "Make & send an object" in references/approval-and-errors.md.
• The user needs a return receipt, a signature or restricted delivery. The certified service is described as certified mail with tracking. Do not promise any extra service the quote does not show.

If the Postedly tools are not available, read references/approval-and-errors.md (Connection) and tell the user how to connect. You can still write the letter and export and check the PDF. Never claim a quote or mailing exists.
