Frequently asked questions

How is PostPal different from emailing or faxing?

PostPal sends real, physical mail via USPS. Emails and faxes are digital. PostPal is the right tool when you need a paper letter delivered to a physical address — for example, an IRS form, a contract, or a notice that requires paper service.

Is there a subscription?

No. PostPal is pay-per-letter. There are no monthly fees, no minimums, and no commitments. Optional bulk pricing applies if you mail multiple letters in one order.

What is the minimum order?

One letter. You can use PostPal as little or as often as you need.

Can a small business use PostPal?

Yes. Small businesses use PostPal to mail invoices, customer letters, and contracts without owning a printer or visiting the post office. Bulk discounts apply on multi-letter orders.

Where is mail sent from?

All mail is printed and posted from inside the United States through USPS, regardless of where you place the order from.
