Mail a letter online when your document is already ready

The quick answer

Upload your document to a print-and-mail provider, check the complete print preview, add the postal address, and pay. PieterPost supports PDFs and images; Mail a Letter Online also accepts Word files and photos for US recipients.

Choose a service that accepts your file

A PDF is useful when you want to keep a finished layout. Word files and photos need a conversion step before printing. A service that performs the conversion should show you the final document, including any address area or sheet.

Mail a Letter Online advertises PDF, Word, and photo support for US addresses. Mailform focuses on PDF mailing. PieterPost combines browser writing with PDF or image upload and US ordinary or Certified mailing options.

Check the printable result

Read every page in the preview. Check that text fits within the margins, photos have the right orientation, and attachments appear in the intended order. Confirm whether the service uses US Letter or A4 paper.

If your document has a signature, check its contrast and size. Confirm that any space reserved for the postal address does not cover important content. Print settings and extra address pages can affect the final price.

Finish with the address and postal class

Enter the complete recipient address, choose a delivery product, and review the full total. For US documents, compare First-Class and Certified Mail separately. Check whether a return receipt is included in the selected Certified order.
