Frequently asked questions about the No2Bounce MCP Server
How do I submit multiple emails for validation at once?
Use the validate_bulk tool and provide an array of email addresses in the emailList parameter. The server will return a trackingId which you can use to check the results.
How can I check if my bulk validation task is finished?
You can use the get_validation_status tool by providing the trackingId received during the submission. It will return the current progress or the final validation results.
