Precleared: cold-email legality checks for AI agents

Is your agent allowed to send that? Precleared answers before the email goes out: a per-address verdict on cold marketing email, the rule quoted, the footer wording, and a signed receipt anyone can verify. Covers the UK (PECR and UK GDPR), the US (CAN-SPAM), Canada (CASL), Germany (UWG) and France.

What the receipt proves

That Precleared was asked this question, with these facts, at this time, and gave this answer. Every receipt has a public page at https://precleared.dev/r/ and can be verified offline with the public key at https://precleared.dev/api/v1/public-key. It is decision support with sources, not legal advice.
