Co-registration leads vs organic signups: the quality math

Co-registration leads vs organic signups: the quality math
Framing line: co-reg fills a list fast and can quietly wreck it. The candid sources price that in.

📥 Swipe
— Co-reg-volume reality check — made the cut for the warning: borrowed-consent leads often don't remember you, so complaints spike.
— Organic-signup LTV comparison — worth your time because it quantifies the gap: organic subscribers out-earn co-reg over any real timeframe.

🚀 Deliverability
— Cold-import warm-up protocol — picked it for the only safe way to mail co-reg: tiny segments, ruthless suppression.

🧪 Tests
— Consent-recall note — earned its spot for the spam-complaint predictor co-reg vendors never mention.

Verdict: organic compounds, co-reg leaks. If you buy leads, isolate them on a sacrificial subdomain.
