Every letter is automatically checked before it can be sent. This screening helps keep the service safe — it blocks content our Terms don't allow, such as content that is threatening, harassing, abusive, fraudulent, deceptive, hateful, or obscene, plus a few practical categories:

* **Inappropriate language** that can't be mailed.

* **Text art (ASCII drawings)** — letters must be plain text.

* **Legal advice or legal citations** — PostalGenie is a correspondence tool, not a law firm, so we can't mail letters that give legal advice. Rewrite it in your own words: describe your situation and what you want, without quoting laws, statutes, or legal conclusions.

* Letters that **score too high on our overall safety review** as written.

If your letter is blocked, the reason appears right under the draft. In most cases the fix is simple: edit the flagged part and continue — the letter is re-checked automatically.

You may also see **cautions** that don't block sending — for example, a reminder that untrue factual claims about a person or company could be libel, or that sensitive personal numbers are visible to anyone who handles the envelope. These are worth reading: you're responsible for what you send.
