Free readiness check
Is your letter ready to send certified?
Paste the letter your assistant wrote and the address it is going to. Piloxa tells you how many pages will print, what the mailing costs, and whether the address has everything USPS needs — before you sign in, and before anything is charged.
No account. Nothing stored. Nothing printed, mailed or charged by this page.
What this check tells you, and what it does not
It tells you the page count produced by the same layout Piloxa prints from, so the number here is the number the review page will show. It tells you the exact all-in total for that many pages, on both services, worked out by the same pricing the checkout uses. And it tells you whether the address has the five parts a USPS envelope needs: a name, a street address, a city, a two-letter state and a ZIP code.
It does not verify the address against USPS records — that happens on the review page, before payment, where a bad address can still be corrected. It does not read a PDF; paste the text instead, or attach the finished PDF after signing in. And it does not keep anything: the letter you paste is laid out to be counted and then discarded, unread by anyone.
What happens next
When the letter and the address look right, the button above takes you to the mailing screen. You sign in with your email address — a one-time link, no password to invent — paste the letter, and see the exact pages, the checked recipient and one total. Nothing is printed, mailed or charged until you authorize it there.
Sending from an assistant instead? How to connect your assistant — it prepares the letter and hands you the same review page.
Common questions
Do you keep my letter?
No. This page sends the text to Piloxa, which lays it out to count the pages and then discards it. Nothing is written down, no account is created, and no record of the check is kept.
Why does the page count matter?
Price depends on how many sheets are printed, and USPS charges a heavier postage rate once the envelope passes one ounce, which is roughly where the fourth page lands. The pricing page shows the cost for every length.
Can I check a PDF?
Not on this page. Paste the text of the document instead, or sign in and attach the finished PDF, which is kept and printed byte for byte.
Mail my letter See what it costs
Status, September 2026: Live mailing is open for letters to any US address. You see the exact letter, the recipient and the total before you pay, and nothing is printed or mailed until you authorize it. Questions: support@piloxa.com.
