Learn Hardcore Norwegian: E-posten bekrefter at møtet er i morgen. - The email confirms that the meeting is tomorrow.

The hyphen is part of the standard spelling e-post (email), connecting the prefix e with post. When you add the definite ending, it becomes e-posten (the email). The initial E is capitalized only because it begins the sentence; otherwise you write e-posten.

Can I write epost without a hyphen?

Yes. In Bokmål, both e-post and epost are accepted. The hyphenated form is common and often preferred in formal writing. The definite forms are e-posten/eposten.

Why is møtet in the definite form?

Because the sentence refers to a specific, known meeting: møtet = “the meeting.” If you said et møte (“a meeting”), it would mean some unspecified meeting. You could say … at et møte er i morgen if that is your intended meaning.
