You can easily log in to Nordweb's email service through webmail. Webmail works directly in your browser, so you do not need a separate email program.
You can also connect your email account directly to your preferred email program, such as Outlook, Thunderbird or your phone's email app. See the separate guide: Connecting an email account to an email program.
If you have forgotten your email account password, you can change it from the Enhance control panel at panel.nordweb.fi. Navigate to Websites → select your site → Emails and change the password for the desired account.
If your business does not yet have its own email, take a look at business email.
