# PostalForm vs Mailform

PostalForm takes you from a blank page or finished PDF to a reviewed mailing without an account. The browser editor, guided forms, address assistance, and agent tools help when the job involves more than uploading an existing document. This PostalForm-authored comparison uses official Mailform sources checked October 15, 2026.

## Why choose PostalForm instead of Mailform?
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.

## From document preparation to a reviewed mailing
| Requirement                       | PostalForm                                                   | Mailform                                                                      |
| --------------------------------- | ------------------------------------------------------------ | ----------------------------------------------------------------------------- |
| Single-recipient browser checkout | No mandatory account                                         | Quick start advertises no signup                                              |
| Document preparation              | PDF upload, browser letter editor and guided forms           | PDF upload, cloud imports and documented integrations                         |
| Preview                           | Printable PDF before payment                                 | Preview control in the upload interface                                       |
| Address assistance                | Loqate-backed lookup and selected-address verification       | Review address requirements in the chosen Mailform workflow                   |
| Certified and receipt             | Certified; optional Electronic Return Receipt where eligible | Pricing page lists Certified, electronic receipt and physical receipt options |
| Automation                        | [Machine API and remote MCP](/developers)                    | API with account and bearer API key                                           |
| Business software                 | Choose the API or supported agent path for integration       | Listed accounting, legal and document integrations                            |

## 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](/pricing) 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](/compare) 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. [Review delivery estimates](/delivery-times) and [full pricing](/pricing).
