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

FAQs+
Does PostalForm decide who must receive the California preliminary notice?
No. The workflow suggests owner, direct contractor, and construction lender roles from California Civil Code section 8200, but you are responsible for confirming the correct recipients.
Can I send to more than one recipient?
Yes. The workflow collects multiple recipients and creates one addressed Certified Mail piece for each selected recipient.
Is this legal advice?
No. PostalForm helps generate, print, mail, and track the packet based on information you provide. It is not a law firm and does not provide legal advice.
