Marketing email carries a working opt-out that keeps working

What the source requires

Every commercial email must carry a functioning opt-out mechanism, clearly and conspicuously displayed, and it must still work for at least thirty days after the message was sent.

Why this is hard to satisfy

Campaign tools bolt an unsubscribe footer on at send time, so nobody checks that the link still resolves a month later — and an expired list, a rotated domain or a retired form turns a lawful send into an unlawful one retroactively.

What we do about it

The opt-out is generated as a signed token carried in the link, so it verifies without a database read and cannot go stale. Suppression is append-only and permanent.
