PostalForm is useful when you want to write a letter, complete a supported guided form, or let an agent prepare a mailing draft as well as upload a PDF. Account-free checkout includes address assistance, printable PDF review, and the full price before payment. Mailform also supports no-signup single-recipient PDF mailing.

Compare the complete quote
PostalForm starts at $3.40 for USPS First-Class Mail, $11.40 with Certified Mail, or $14.40 with Certified Mail and Electronic Return Receipt for a one-page black-and-white U.S. document plus the inserted address page. These starting configurations include printing and mailing; document, destination, options, and fulfillment route determine the final quote.
Mailform's pricing details list $2.99 for the first page, $0.49 per additional printed page, a $0.49-per-sheet single-sided charge, and separate color and service charges. Certified Mail is listed as an $8.99 add-on and Electronic Return Receipt as another $3.02. Use Mailform's calculator to resolve the exact configuration rather than adding a headline price without checking printing assumptions.
PostalForm's full-disclosure pricing matrix explains its base fee, printing, inserted address page, and receipt options. Match page count, sides, color, destination and receipt type. PostalForm's checkout quote is the amount to review before payment; a comparison page is not a substitute for either service's final quote.
PostalForm's three tasks
| Task | PDF upload | Browser letter |
|---|---|---|
| 1. Prepare | Upload and inspect the PDF | Write and inspect the generated PDF |
| 2. Address | Add sender, recipient and mailing choices | Add sender, recipient and mailing choices |
| 3. Approve | Review the printable document and quote, then pay | Review the printable document and quote, then pay |
These are three task groups, not measured screen counts or completion times. PostalForm keeps document preparation, address checks, and payment review available in the single-letter flow.
Choose by requirement
| Use PostalForm when | Consider Mailform when |
|---|---|
| You want a browser letter editor or supported guided form | You already use a listed Mailform business integration |
| You want an agent to prepare a supported form or mailing draft through MCP | You want to integrate directly with Mailform's API |
| PostalForm's exact proof and print configuration fits the task | Mailform's quoted service, carrier or receipt configuration fits better |
For signature proof, distinguish Certified tracking from the separate receipt. For speed, distinguish production from carrier transit. The delivery and proof matrix explains PostalForm's options and evidence limits.

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
