Official Solution & Step-by-Step Guide:

【Official Architecture & Standard Operating Procedure】 Each account is bound to a dedicated static residential proxy IP — no two accounts ever share the same egress IP, which is the #1 trigger for account-linkage bans. Native protocol drivers connect directly with no third-party relay, simulating human typing cadence and presence states to reduce behavioral-anomaly flags. New numbers should go through a 7-day warm-up: start with low daily volume and avoid bulk sends or cold outreach in the first few days. The Account Health dashboard shows real-time send success rate, latency, and a risk score per account, so issues surface before a ban happens, not after. You can bring your own static residential proxy provider, or one-click purchase managed proxies by region directly in Account Settings — the system auto-binds them and never reuses the same egress across accounts.
