What is webmail?

Webmail is email you access through a browser. Think Gmail.com or Outlook.com.

The processing happens on the provider's servers; you interact through a graphical web interface.

The advantage is accessibility from any device with an internet connection. The trade off is dependence on that connection.

Modern webmail platforms are secure, constantly updated, and usually safer than unpatched local software.

Always use strong passwords and enable multi factor authentication.
