Coding Assessment – Support Emails Classification

📌 Overview

This project is a solution for the Unstop Coding Assessment Challenge.
The dataset contains support emails (sender, subject, body, sent_date).
We classify each email into categories such as Billing Issue, Login Issue, Integration Query, or General Query.
