## Overview

MailerPro is an email-campaign management application. Users sign in, manage contacts and campaigns, configure email delivery, and view subscription and usage information through a React frontend backed by a Python service. The sampled frontend excerpt confirms these product areas, but does not show its API calls; backend internals and persistence are not described in the supplied evidence, so those connections are left unverified rather than inferred.

Main entry points: [`frontend/src/App.js`](https://github.com/wahhabriaz/email-automation-platform/blob/main/frontend/src/App.js) (Frontend application), [`backend/server.py`](https://github.com/wahhabriaz/email-automation-platform/blob/main/backend/server.py) (Backend server), [`backend/email_service.py`](https://github.com/wahhabriaz/email-automation-platform/blob/main/backend/email_service.py) (Email service), [`frontend/src/components/ui`](https://github.com/wahhabriaz/email-automation-platform/tree/main/frontend/src/components/ui) (Reusable UI controls)
