Which mailing option and proof should you choose?
PostalForm offers U.S. letter mailing with different delivery and proof options. First-Class suits routine correspondence; Certified Mail adds mailing and delivery records, and Electronic Return Receipt adds a downloadable signature record. Expedited delivery prioritizes speed. Review the destination, estimated dates, total price, and required proof before paying.
| Mailing option | Delivery speed | Proof | Use when | Avoid when |
|---|---|---|---|---|
| USPS First-Class Mail | First-Class Mail delivery estimate shown before payment. | Available processing scans; no recipient signature or Certified Mail receipt. | Routine letters when a signed delivery record is unnecessary. | Your instructions require Certified Mail, a signature, or a deadline this estimate cannot meet. |
| Certified Mail | First-Class delivery speed; certification does not make delivery faster. | USPS mailing and delivery/attempt tracking; no Electronic Return Receipt unless added. | You need a recorded mailing and delivery or attempted-delivery status. | You need a downloadable signature record or faster delivery. |
| Certified Mail + Electronic Return Receipt | First-Class delivery speed; signature collection may require redelivery or pickup. | Certified Mail records plus a downloadable USPS signature record when available. | Your instructions call for Certified Mail with Return Receipt or you need the signature record. | Your recipient requires an original enclosure, personal service, or another submission method. |
| Expedited / Express with signature | Faster estimated delivery range shown at checkout; production cutoff and destination apply. | Carrier tracking and signature option; this is separate from Certified Mail and ERR. | Speed and signature matter and checkout offers the service for your destination. | A rule specifically requires Certified Mail or the displayed estimate misses your deadline. |
Availability and delivery estimates depend on the document and destination. Mailing proof does not establish that a recipient accepted a filing or that legal service requirements were met. Delivery estimates · Full pricing
