Free readiness check
Is your letter ready to send certified?
Paste the letter your assistant wrote and the address it is going to. Piloxa lists what still needs fixing (placeholders left in, missing address parts, enclosures the letter mentions, blank pages), how many pages will print and what the mailing costs, before you sign in and before anything is charged. One button copies the fixes for your assistant.
No account. The check stores nothing. Nothing printed, mailed or charged by this page.
What this check tells you, and what it does not
It lists what is unfinished or missing in the letter itself: placeholders such as [NAME] or “insert date” left in, a signature line with no name, text an assistant added around the letter, enclosures the letter mentions that will not be in the envelope, a missing return address, a page left blank, and a last page carrying only a line or two. Each item is marked either as something to fix before mailing, or as something to check yourself because it may be deliberate. It never says whether the letter is legally sufficient; that depends on your situation and the law that applies to it.
It also 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 the check itself keeps nothing: the letter you paste is laid out to be counted and then discarded, unread by anyone.
Copy fixes to my AI
When the check finds something, one button writes the findings as a short instruction for your assistant: fix only these items, keep every other word, invent no facts, names, dates, amounts or addresses, and ask you when something is missing. It ends with a private link back to your letter on Piloxa, which works for three days. Pressing it saves the letter as a private, unsent draft in this browser so that link can bring you back to it; copying sends nothing anywhere until you paste it yourself. When you come back you paste or upload the corrected letter, the recipient and service stay filled in, the check runs again, and you read the new pages before anything is paid for.
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?
Not for the check. The text is laid out to count the pages and look for problems, then discarded; no account is created and nothing you typed is written down. Only if you press “Copy fixes to my AI” is the letter saved, as a private unsent draft tied to this browser, so the link in the report can bring you back to it. You can discard it on the mailing screen.
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.

Status, November 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.
