Writing letters may be a dying art to some extent, but the need to write a polite email or other message is still alive and well. Unlike in Swedish, you can still use kjære, the Norwegian equivalent of "dear", which in Swedish would be like writing "dear beloved". You might start off a formal email with a short Takk for raskt svar (which translates to "Thank you for the quick reply"), Jeg sender deg... ("I am sending you..."), or a few words on how you got the recipient's contact information, such as Jeg fikk kontaktinformasjonen din fra Stian ("I got your contact information from Stian").
