Nogle af de nye emails havner i spam, selv om de ser vigtige ud.

Nogle af means some of.

• nogle = some
• af = of

So Nogle af de nye emails means some of the new emails.

You use af because you are talking about some from a specific group: de nye emails = the new emails.

Compare:

• Nogle emails = some emails
• Nogle af de nye emails = some of the new emails

De nye emails means the new emails, while nye emails just means new emails.

In Danish, when a plural noun is definite and has an adjective, you normally use:

• de
  • adjective + noun

So:

• nye emails = new emails
• de nye emails = the new emails

This is a very common pattern in Danish.

Danish often uses the loanword email (or e-mail) in everyday language. In the plural, many speakers write emails.

So:

• en email = an email
• emails = emails

You may also see other spellings, but emails is very common and natural in modern Danish.

Havner comes from at havne, which literally means something like to end up or to land somewhere.

In this sentence, havner i spam means:

• end up in spam
• land in the spam folder

So it suggests that the emails are not intentionally put there; they just end up there.

In everyday Danish, i spam is a very natural shorthand for in the spam folder or in spam.

It works much like English speakers saying:

• It went to spam
• It ended up in spam

A fuller version like i spammappen is also possible, but i spam sounds concise and idiomatic.

Selv om means although, even though, or though.

It introduces a contrast:

• the emails end up in spam
• despite the fact that they look important

So the second part explains why the first part is surprising.

Here de is a pronoun meaning they. It refers back to de nye emails.

So:

• de nye emails = the new emails
• de = they

The sentence avoids repeating emails by using the pronoun instead.

The expression is at se ... ud, which means to look ... in the sense of appear.

So:

• de ser vigtige ud = they look important

The word ud is part of the expression. Without ud, ser usually means more literally see or are looking at something, depending on context.

This split verb pattern is very common in Danish:

• ser ... ud
• finder ... ud
• går ... ud

Because it describes de = the emails, which is plural.

In Danish, adjectives usually agree with the noun they describe. Here:

• en vigtig email = an important email
• vigtige emails = important emails

So in de ser vigtige ud, vigtige must be plural because they refers to multiple emails.

It is a subordinate clause introduced by selv om.

The basic order here is:

• de = subject
• ser = verb
• vigtige = adjective complement
• ud = particle

So: selv om de ser vigtige ud = even though they look important

Nothing unusual happens here beyond the fact that ser ... ud is a split expression.

A useful thing to remember is that Danish subordinate clauses often differ from main clauses especially when words like ikke are present. For example:

• main clause: De ser ikke vigtige ud
• subordinate clause: ... selv om de ikke ser vigtige ud

So subordinate clauses are worth paying attention to.

No. It is clearly plural.

You can tell because:

• nogle usually refers to more than one
• de is plural here
• nye is the plural/common form of the adjective
• emails has the plural ending -s

So the sentence is definitely talking about multiple emails.

It is in the present tense:

• havner = end up / are ending up
• ser = look

In Danish, the present tense often covers both a general truth and something that happens regularly. So this sentence can mean something like:

• Some of the new emails end up in spam
• Some of the new emails are ending up in spam

depending on context.
