Roundcube is a free, open-source webmail client that allows you to access your email directly through your web browser. Unlike desktop email programs, Roundcube runs on your hosting server and provides a user-friendly interface similar to popular email services like Gmail or Outlook.com.

When your hosting provider includes Roundcube, you can check your professional email addresses (like you@yourdomain.com) from any device with an internet connection. Key features include:

• Intuitive Interface: A clean, three-panel layout for folders, message lists, and reading.
• Rich Text Editor: Compose formatted emails with attachments easily.
• Contact Management: Built-in address book to store your contacts.
• IMAP Support: Emails stay synchronized on the server.
• Plugin System: Extend functionality with calendar, tasks, or security add-ons.

To access Roundcube, you typically log in through your hosting control panel (like cPanel) or via a direct link provided by your host, using your full email address and password. It's an excellent solution for managing business or personal email associated with your domain, offering privacy and control as your data resides on your hosting account.

If you encounter issues, common fixes include checking your login credentials, ensuring your domain's mail services are active, and clearing your browser's cache. For advanced configuration, consult your hosting provider's support.
