Integration details

Description

Prepare one unpaid plain-text letter in Claude for printing and mailing to a US postal address. Supply the letter text, a US recipient address and a US return address. Open the saved draft in Postmarkr to review every printed page, addresses and the current total, then explicitly pay in your browser for USPS First-Class mail. Ask Claude for status using a known letter ID. Connecting grants no spending authority; these tools cannot charge you or dispatch mail. Saving creates a visible template and draft, and may save address-book entries and start address checks and preview generation. Retry unchanged details with the same request key to recover the same available unpaid draft. This connector does not support PDF attachments, bulk mail, international destinations, Certified Mail, letter-history search or autonomous payment.
