Arduino Wi-Fi Notification System

I'm looking for a hardware and programming solution to enable an Arduino to send either a text or an email over Wi-Fi.

Requirements:
- Use of Wi-Fi for communication
- Capability to send either texts or emails (whichever is simpler)
- Flexibility in choosing the platform for sending notifications (SMS, instant messaging, etc.)

Ideal Skills & Experience:
- Proficiency in Arduino programming
- Experience with Wi-Fi communication modules (like ESP8266 or ESP32)
- Familiarity with SMS and email APIs
- Knowledge of various messaging platforms and their integration with Arduino

Please provide a solution that is reliable and easy to implement.
