-# Mail Checker
+# 📨 Mail Checker
 
 A small Flask application to check the email provided, return score and determine if it's valid or not.
 
+This app can detect:
+
+* common pattern typos and make domain suggestions (eg. `gemail.com`)
+* some **Disposable Email Addresses** (DEA) - aka temporal emails
+* domains used on public email services
+* domains that do not exist (checks DNS records) or cannot receive emails
+
 ### Usage
 
 Call endpoint `GET /[email protected]` or `POST /check` with JSON `{"email": "[email protected]"}`.
 
+Alternatively, execute `app.py [email protected]` to check one single address.
+
 ```sh
-curl -H  "Content-Type: application/json" --data '{"email": "[email protected]"}' localhost:5000/check
+curl -H  "Content-Type: application/json" localhost:5000/check --data '{"email": "[email protected]"}'
 ```
