Der Zustellnachweis kommt per E-Mail.

Der is the masculine singular definite article, so it tells you that Zustellnachweis is a masculine noun.

Here, der Zustellnachweis means the proof of delivery / the delivery confirmation.

In this sentence, der Zustellnachweis is also the subject, which is why it appears in the nominative case:

• Der Zustellnachweis kommt per E-Mail.

If you changed the sentence so the noun became an object, the article might change depending on the case:

• nominative: der Zustellnachweis
• accusative: den Zustellnachweis
• dative: dem Zustellnachweis
• genitive: des Zustellnachweises

German very often combines nouns into one compound noun.

Zustellnachweis is made up of:

• Zustellung = delivery
• Nachweis = proof, evidence, confirmation

In compounds, the last part is the main noun and determines the grammatical gender. Since Nachweis is masculine (der Nachweis), the whole compound is masculine:

• der Zustellnachweis

This is a very normal feature of German. English often uses separate words where German prefers one compound.

In a normal German main clause, the finite verb usually goes in position 2.

The sentence is structured like this:

• Der Zustellnachweis = position 1
• kommt = position 2
• per E-Mail = the rest of the sentence

So this follows the standard German word order pattern:

• Subject + verb + other information

You could also move another element to the first position, but the verb would still stay in second position:

• Per E-Mail kommt der Zustellnachweis.

That version is grammatically correct, but the original is more neutral.

Yes, kommt literally means comes, from kommen.

But German often uses kommen in situations where English might prefer something like:

• arrives
• is sent
• is delivered
• comes through

So:

• Der Zustellnachweis kommt per E-Mail.

can naturally mean that the delivery confirmation arrives by email or is sent by email.

This is a good example of why you should not always translate word-for-word. The German wording is idiomatic.

Per E-Mail means by email or via email.

The preposition per is used to express the means or method by which something is sent or happens:

• per E-Mail = by email
• per Post = by post
• per SMS = by text message
• per Einschreiben = by registered mail

In modern German, per is often used without an article, especially in fixed expressions like this. That is why you do not say:

• per der E-Mail

You simply say:

• per E-Mail

Because per E-Mail is a fixed, common expression.

German often omits the article after per in this kind of phrase:

• per E-Mail
• per Post
• per Telefon (less common nowadays, but possible in some contexts)

Even though E-Mail is normally a noun with a gender:

• die E-Mail

after per, the article is usually left out.

A learner might expect something like per die E-Mail, but that is not correct.

It is capitalized because all German nouns are capitalized.

So:

• die E-Mail
• der Zustellnachweis

The hyphen in E-Mail is simply part of the standard spelling of the word in German. It is a borrowed term based on electronic mail, and German normally writes it as:

• E-Mail

Its plural is:

• die E-Mails

Normally, per E-Mail is the most natural choice here.

Other options:

• via E-Mail = also common and natural
• durch E-Mail = usually not idiomatic here
• mit E-Mail = usually sounds wrong or unnatural for by email

So the best choices are:

• Der Zustellnachweis kommt per E-Mail.
• Der Zustellnachweis kommt via E-Mail.

Of those, per E-Mail is especially standard in practical, business, and administrative contexts.

It is understandable and correct, but it sounds somewhat formal or administrative.

You are likely to see it in contexts like:

• shipping
• online orders
• postal services
• tracking and delivery systems
• official communication

That is very typical for German: formal and technical contexts often use precise compound nouns like this.

Yes, it is in the present tense:

• kommt = comes / is coming / arrives

In German, the present tense is very often used for future meaning when the context makes it clear. So this sentence can mean something like:

• the confirmation comes by email
• the confirmation will come by email

German does not always need a separate future form like English will come.

If needed, German can also use werden for future:

• Der Zustellnachweis wird per E-Mail kommen.

But that sounds less natural in many everyday contexts than the simple present.

The plural of der Zustellnachweis is:

• die Zustellnachweise

So the sentence becomes:

• Die Zustellnachweise kommen per E-Mail.

Notice the changes:

• der → die
• kommt → kommen

That is because the subject is now plural.

Yes. In natural English, arrives by email is often the better translation.

German kommen has a wider everyday use than English come in some contexts. So depending on the situation, these can all be reasonable translations:

• The proof of delivery comes by email.
• The proof of delivery arrives by email.
• The proof of delivery is sent by email.

The exact best English wording depends on the context, but the German sentence itself is perfectly normal.
