Nordweb's webmail is a browser-based email application that lets you read and send email from anywhere, without separate software.
There are two webmail addresses because there are two email platforms. The Webmail button in your account always takes you to the one that holds your mailbox, so use it instead of a bookmark. Signing in at the wrong address will not work even with the right password.

You can create automatic filters that move certain messages into folders of your choice. This makes it easier to keep your email organized as the volume of messages grows.
If your business does not yet have its own email, take a look at business email.
