关于产品
Clean your email list before you send. Upload a CSV or use the API: every address comes back valid, invalid, catch-all, risky or unknown, with a score and a plain-English reason. What's different: catch-all and unknown results are refunded, duplicates are charged once, credits never expire, no subscription. 100 free checks every month, EU servers, API, webhooks and an MCP server for AI agents.
