HTML Email Support: Create rich HTML emails using a built-in text editor.
Live Preview: A split-screen view with a Web Engine preview pane to see exactly how the email will look before sending.

Multi-Recipient Support: Send emails to a list of recipients pasted directly into the text area.

Delay: Set a specific wait time (in seconds) between sending each email to avoid being flagged as spam.
Rate Limit: Set a maximum number of emails to send per session.
Multi-threaded Sending: The email sending process runs in a separate background thread, keeping the UI responsive (you can still move the window or check other tabs while sending).

Progress Tracking: A progress bar and status label show the current progress of the campaign.
Real-time Logging: A table logs every attempt with a timestamp, recipient, status (Success/Failed), and detailed error messages.

Export Logs: Ability to export the sending log to a CSV file for analysis.
SSL/TLS Encryption: Securely connects to mail servers using Python’s `ssl` library.
Local SQLite Database: No external database server required; all data is stored locally in a single file (`email_sender_pro.db`).
Fallback Icons: Includes logic to handle missing image assets by using standard system icons, preventing UI breakage.
