Clean massive email lists inside Claude Desktop

Call `validate_bulk` on this MCP Server to drop a dirty list of addresses straight into your chat. Your AI client starts the verification and returns a tracking ID immediately. No more exporting CSVs, logging into separate portals, or waiting around. Claude tracks the entire job in the background. Once it finishes, the tool hands back clean data so you can update your CRM or cold outreach campaigns on the spot. It keeps your sender reputation safe without breaking your focus.

Check verification status with this MCP Server

Invoke `get_validation_status` to check the progress of your active lists without guessing. Your agent pulls live updates directly into your conversation so you can see exactly how many addresses passed. You get a clear picture of your bounce risks instantly. This direct connection means you never have to refresh a dashboard. Claude reads the raw JSON payload and summarizes the bounce risks for you. You get clean lists and fewer bounces with zero manual work.

Protect sender reputation during Claude Web chats

Run `validate_bulk` directly from your browser when using the web version of Claude. Your agent triggers the verification on your target lists while you draft marketing sequences in the same tab. This setup stops bad addresses from creeping into your campaigns. By filtering out hard bounces before you hit send, you keep your domain off spam blocklists.
