HOW TO USE:
Save the Script: Save as mass_email.py.
Run in Terminal: Use python3 mass_email.py.
Follow Prompts:
• Choose provider (gmail/yahoo/icloud).
• Enter your email and password (use an app-specific password for Gmail/iCloud; Yahoo may require similar setup).
• Enter subject and body (multi-line body ends with a blank line).
• Enter up to 500 recipient emails (one per line, blank line to finish).
• Confirm to send.
• Choose provider (gmail/yahoo/icloud).
• Enter your email and password (use an app-specific password for Gmail/iCloud; Yahoo may require similar setup).
• Enter subject and body (multi-line body ends with a blank line).
• Enter up to 500 recipient emails (one per line, blank line to finish).
• Confirm to send.
Dependencies: None beyond Python 3 standard library (smtplib, email, threading, getpass, re).
SETUP:
Gmail: Enable 2FA and generate an app-specific password (Google Account > Security > App Passwords).
• iCloud: Generate an app-specific password (Apple ID > Password & Security).
• Yahoo: May require app-specific password or enabling “Allow apps that use less secure sign-in” (check Yahoo account settings).
• Security: Passwords are hidden during input (getpass) but stored in memory during execution. Use on a trusted device.
• iCloud: Generate an app-specific password (Apple ID > Password & Security).
• Yahoo: May require app-specific password or enabling “Allow apps that use less secure sign-in” (check Yahoo account settings).
• Security: Passwords are hidden during input (getpass) but stored in memory during execution. Use on a trusted device.
PERFORMANCE:
Speed: Sends ~500 emails in seconds by using threading (each email in a separate thread). A 0.1-second delay between threads prevents overwhelming SMTP servers.
• Limitations: Actual speed depends on network, provider rate limits, and server response. 500 emails may take ~50-60 seconds due to delays and server handshakes.
• Threading: Lightweight threading avoids heavy dependencies like asyncio or external libraries.

SAFETY FEATURES:
Validation: Only allows @gmail.com, @Yahoo.com, @iCloud.com addresses.
• Error Handling: Catches authentication failures, invalid emails, and SMTP errors.
• Rate Limiting: 0.1-second delay between emails to reduce risk of bans.
• Interruptible: Ctrl+C stops the script safely.
