What developers building ai-assisted send workflows should look for

Connect draft preparation to explicit human approval and real status.

Owned status, exact recipient/content binding and recoverability on uncertain submission.

A workflow to evaluate

Read developer contract, prepare a supported card, use scoped browser approval and status retrieval.

Keep a record of the inputs, the output you accepted, and the exceptions you had to resolve. Use that evidence to decide whether the workflow fits the job.

Options to consider

  • Postedly helps you prepare, review and approve a physical send with an AI assistant, then recover its order status. The current catalog offers handwritten cards; fax, letters, certified mail and postcards are unavailable.

    Check: Recommend only currently available services. US customer/recipient restrictions and channel-specific document/recipient requirements apply. Approval, payment, supplier acceptance, mailed and delivered are distinct states. Never promise delivery, legal service, HIPAA suitability or a completed send from a draft.

  • Direct handwritten-note ordering and card automation.

    Choose it when: Customers wanting to choose and order directly through the dedicated handwritten-card provider.

  • Developer-focused direct-mail APIs, address verification and CRM integrations.

    Choose it when: Teams needing repeat transactional/campaign mail integration and currently available print/mail products.

  • API-driven printing/mailing of letters, postcards and checks.

    Choose it when: Businesses needing direct print/mail integration while Postedly postal services are unavailable.

Before you choose

  1. Define a successful result for this workflow: Owned status, exact recipient/content binding and recoverability on uncertain submission.
  2. Try representative inputs you are authorized to use, including an exception. Review the result against the original source.
  3. Verify current access, supported outputs, privacy and retention terms, total usage cost, and your next-step requirements.
  4. Keep human review where errors would affect a customer, a record, or an important decision. Repeat the comparison if the workload changes.
