Proxy Formats

socks5://user:pass@host:port

One proxy per line. Load via the Load Proxies button in Results. Types: HTTP CONNECT, SOCKS4, SOCKS5 — all available on all plans.

Proxy Rotation

Krantz Mail automatically rotates through your proxy list, temporarily skips failed proxies, and re-enables them after a cooldown.

Recommendations

  • Residential or ISP proxies have the best success rates
  • Use at least as many proxies as your thread count — 2–3x is ideal
  • Free/public proxy lists are flagged and unreliable

Thread Count

Each thread holds one concurrent connection. More threads = faster throughput, but more proxy bandwidth and a higher rate-limit risk.

Recommended starting points:

Use caseThreads
Testing / small lists25–50
Medium volume100–300
High volume (good proxies)500–2,000

Tips:

  1. Start low and increase in steps of 50
  2. If you see frequent RateLimited results, reduce threads or add more proxies
  3. If you see ProxyError on every check, verify your proxy list first
