Print and mail a letter online

Online letter mailing

Need to mail a letter or PDF, but do not want to deal with the printer, envelope, stamp, and post office trip? PieterPost lets you write online or upload a document, then turns it into regular physical mail for the recipient.

Use PieterPost when you have words or a PDF, the recipient needs a physical letter, and you want the printing, postage, and mailing steps handled without a post office trip. Standard delivery is the default; for an eligible U.S. letter, you can add USPS Certified Mail with tracking and a signed electronic return receipt before checkout.

Frequently asked questions

Can I print and send a letter online?

Yes. Write your letter in PieterPost or upload a PDF, add the recipient address, review the preview, and complete checkout. PieterPost prepares the physical letter and puts it into the mail.

Can I send a PDF by mail?

Yes. You can upload a PDF and send it as a physical letter. Check the preview before checkout so you know how many pages will be mailed.

When should I use an online letter mailing service?

PieterPost is useful when you need a physical letter but do not want to print, fold, address, stamp, and mail it yourself. Registered delivery is also available for selected countries; check the exact evidence and destination before relying on it.

How much does it cost to mail a letter online?

The live checkout calculates the price from the destination, number of recipients, number of pages, uploads, and selected options before you pay.

Does PieterPost offer certified mail or tracking?

For selected destination countries, PieterPost offers registered delivery with tracking and delivery confirmation before checkout. The exact evidence differs by country, and it does not automatically replace formal legal service.

Can I send the same letter to multiple recipients?

Yes. Add multiple recipients manually, upload a CSV, or use Mailbook contacts. US and non-US recipients can be included in the same letter order.

Why send a letter instead of an email?

Use email when speed matters more than format. Use a physical letter when the message should arrive on paper, needs an attached PDF, feels more official, or should stand apart from inbox noise.
