webmail

noun

web·​mail ˈweb-ˌmāl 

: an email account or service that is accessed through a web browser

The disadvantages of webmail are you need an internet connection to read or send messages and your email and contacts are stored in the cloud. However, there's no program to install, your email and contacts can be accessed anywhere on any computer or device, and if you switch to a new ISP your email address stays the same.

—Ray Saitz

Her initial campaign emails … didn't render correctly on mobile phones and on webmail.

—Colin Delany
