## Overview

This is a standard-library Python CLI for safely bulk-changing Yandex 360 employees’ default sender addresses. An administrator exports employees, edits the CSV, confirms a validated change plan, and the CLI applies sequential PATCH requests while recording outcomes. The README documents the workflow and modes; sampled source supports the API client, export, validation, and command entry point. Some execution details fall in omitted excerpts, so uncertain internal links are omitted.

Main entry points: [`default_email.py`](https://github.com/milekhinav/y360_default_email_for_users/blob/main/default_email.py) (CLI orchestration)
