[CUSTOM] Calls the Marketo REST API directly (not Adobe's native MCP).
AI agents call custom_delete_email_template2 to permanently remove resources in Marketo MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of email templates is a destructive action that cannot be undone and could impact ongoing email campaigns and marketing operations.

From the tool's definition Tool name contains 'delete' applied to 'email_template', and description states it 'Calls the Marketo REST API directly'. The delete operation on email templates is irreversible and will remove marketing assets.
