List recent emails sent via Resend.
AI agents call resend_list_emails to retrieve information from Integrations MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries email history from the Resend service. The 'list' operation is inherently read-only; it does not create, modify, delete, execute, or trigger external operations. The blast radius of misuse is low since reading email metadata poses minimal risk compared to sending emails or accessing sensitive account operations.
From the tool's definition Tool name contains 'list' and description states 'List recent emails sent via Resend' — a query operation that retrieves data without modification or side effects.
