Return Receipt is a separate service that provides a delivery record including a signature. These are distinct from ordinary postal progress updates. Postedly’s current catalog describes its certified service as USPS certified mail with a tracking number. Do not assume that a return receipt, restricted delivery, or another extra service is included. Use only the mailing options supported by the selected product and quote. - [USPS: Certified Mail and extra services](https://www.usps.com/ship/insurance-extra-services.htm) - [USPS: Return Receipt basics](https://faq.usps.com/articles/Knowledge/Return-Receipt-The-Basics) ## Decide what evidence you need before sending First identify the exact evidence requested by your recipient or adviser: a mailing record, a tracking update, a delivery or attempted-delivery record, or a separate return receipt. These records answer different questions. USPS describes Return Receipt as a separate service that can provide a delivery record with a signature. Check the actual Postedly quote and service description for what is available. If the required record or extra service is not shown, do not assume it will be supplied; choose a service that explicitly provides what you need. A payment receipt or print-ready proof does not itself show the mail was accepted or delivered. - [USPS: Certified Mail and extra services](https://www.usps.com/ship/insurance-extra-services.htm) - [USPS: Return Receipt basics](https://faq.usps.com/articles/Knowledge/Return-Receipt-The-Basics) ## Start with a finished PDF Use an unencrypted PDF, at most 10 MiB, with portrait US Letter pages measuring 8.5 × 11 inches. Save your final wording into the file before requesting a quote. Postedly prints the file you approve. - A separate address page is added to letters and certified mail. Review its placement in the final proof. - The upload system accepts PDFs with 1–50 pages, but this is not a mailing allowance. The current letter service permits at most six physical sheets including its address sheet; the selected mailing and printing options can have lower page limits. - A document that uploads successfully can still fail the service-specific quote checks. Follow the returned page or size correction before trying again. - [Help your assistant access the PDF](https://postedly.com/guides/ai-cant-access-pdf) ## Prepare one certified mailing 1. ### Confirm the required mailing method. Check the recipient’s instructions and your purpose before selecting the service. This guide explains the sending workflow and does not establish whether a mailing satisfies a legal notice or filing requirement. 2. ### Choose Certified mail. Check availability, transfer the finished PDF, and provide complete US sender and recipient addresses. Ask for the exact mailing service to be shown in the quote. 3. ### Approve the final proof and total. Review the added address page and every document page. Confirm addresses, service, estimated timing, and total before proceeding to payment. 4. ### Retain the order and available evidence. Check the existing order for provider updates and any returned tracking information. A payment receipt alone does not establish mailing or delivery. Example request > Use Postedly to prepare a certified mail quote for this finished PDF and the US address I provide. Show the supported mailing service, final proof, recipient, and total. Do not add unconfirmed return-receipt or signature options. Wait for my approval before payment. ## Timing and what the status means Printing and postal transit take several business days. Use the estimate shown in your quote; it is not a guaranteed arrival date. Order updates can show preparation, printing, and postal progress. A sent update or estimated arrival does not necessarily confirm that the recipient received the item. Read the sending record for the evidence actually available. - [Understand quotes, payments, and delivery status](https://postedly.com/guides/understand-order-status) ## Ready for the next step?
