Open workflowWhy this topic matters
These demand letters workflows are for mailings where the form, supporting documents, and proof of sending need to stay together. PostalForm turns selected printable PDFs and packet workflows into guided online steps, then generates a reviewable PDF before mailing.
How it works
- Choose the workflow that matches the packet you need to send
- Answer the guided questions and upload attachments when needed
- Review the generated PDF before checkout
- PostalForm prints and mails the packet through USPS
