Verify if an email address is valid and active.
AI agents call prospeo_verify_email to retrieve information from Prospeo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The operation has minimal blast radius—incorrect verification results do not cause irreversible harm or financial impact. Confidence is high because the description unambiguously describes a passive lookup operation.
