Consent tracking, compliance footers and sending-health guardrails

Sending marketing email responsibly is now built in. Every campaign automatically carries your business's postal address and Privacy/Terms links in its footer - set your address once in Settings → Email, and campaigns won't schedule without it (it's the law). We now record how and when every contact consented - double opt-in, a form, the preference center, an attested import or a manual add - shown right on each list with a consent-mix summary, so you can always answer "how did this list get built?". Adding contacts runs an address hygiene check (valid syntax, real mail domains, and blocked watchdog addresses like postmaster@), and bulk imports require you to confirm the recipients actually opted in. Finally, Solstral watches your bounce and complaint rates: campaigns from an unhealthy domain are warned or blocked before they send, and if things get bad enough your marketing pauses automatically to protect your sender reputation - one-to-one and transactional email keep flowing.
