Meld een zoekgeraakte bestelling direct bij de webwinkel.

Because meld is an imperative form: it gives an instruction or command, like Report ... in English.

The base verb is melden = to report.
In the imperative, Dutch often uses just the verb stem:

• melden → meld

So Meld een zoekgeraakte bestelling ... means Report a missing/lost order ...

Dutch imperatives often leave out the subject, just like English:

• Come here.
• Read this.
• Report it immediately.

In Dutch, imperatives normally do not need an explicit subject.

So instead of saying:

• Jij meldt ...
• U meldt ...

you simply say:

• Meld ...

This is the normal way to give instructions on websites, signs, manuals, and customer-service pages.

If you want to make it explicitly polite, Dutch can use:

• Meldt u een zoekgeraakte bestelling direct bij de webwinkel.

But the shorter Meld ... is very common in general instructions.

Zoekgeraakte is an adjective meaning something like that got lost or that went missing.

It comes from the verb zoekraken, which means to get lost / to go missing.

Its past participle is:

• zoekgeraakt

When that participle is used before a noun as an adjective, it usually gets -e:

• een zoekgeraakte bestelling

So literally it is something like:

• a gone-missing order
• more natural English: a missing order or a lost order

Because in Dutch, adjectives placed before a noun usually take an -e ending.

Here, zoekgeraakt is being used like an adjective before bestelling:

• zoekgeraakt → predicate form
• zoekgeraakte bestelling → attributive form

So:

• De bestelling is zoekgeraakt. = The order got lost.
• een zoekgeraakte bestelling = a lost/missing order

That -e is very common in Dutch adjective patterns.

Een is the indefinite article, like a/an in English.

So:

• een bestelling = an order
• de bestelling = the order

The sentence is talking about a lost order in general, not a specific already-identified one, so een makes sense.

If you were talking about one specific order already known in the conversation, you might say:

• Meld de zoekgeraakte bestelling direct bij de webwinkel.

But in general instructions, Dutch often uses een.

Here bij means something like with, to, or at the webshop/store in the sense of filing a report with them.

With melden, Dutch often uses bij when you report something to an organization, authority, or company:

• iets bij de politie melden = report something to the police
• iets bij de gemeente melden = report something to the municipality
• iets bij de webwinkel melden = report something to the web shop

So bij is the natural preposition here.

• naar would sound more like physical movement to/toward
• aan is generally not the normal choice with melden in this pattern

Here direct means immediately / right away.

So the idea is:

• Report a missing order right away to the webshop.

In Dutch, direct is very commonly used where English would often say immediately.

It can sometimes also mean directly, depending on context, but in this sentence the time meaning is the natural one.

Because Dutch adverbs like direct are fairly flexible, but this position sounds natural and clear.

The structure here is:

• Meld — verb
• een zoekgeraakte bestelling — object
• direct — adverb
• bij de webwinkel — prepositional phrase

So the sentence flows as:

• Report a missing order immediately with the webshop.

You could also hear:

• Meld direct een zoekgeraakte bestelling bij de webwinkel.

That is also possible. The version in your sentence puts the object first and then adds direct.

Yes. Dutch very often forms compound nouns by writing them as one word.

So:

• web
  • winkel → webwinkel

This is completely normal in Dutch. English often writes similar ideas as two words, but Dutch usually combines them.

Other examples:

• boekwinkel = bookshop
• supermarktketen = supermarket chain
• klantenservicepagina = customer service page

You may also see webshop, which is another common word with a similar meaning.

In a normal statement, Dutch follows the usual verb-second pattern.

For example:

• U meldt een zoekgeraakte bestelling direct bij de webwinkel.
• Je meldt een zoekgeraakte bestelling direct bij de webwinkel.

That means:

• You report a missing order immediately to the webshop.

So compare:

• Meld ... = imperative / instruction
• U meldt ... = statement

This is why the command form looks a little different from the ordinary present-tense sentence.

Sometimes, but zoekgeraakte bestelling is more precise for an order that has gone missing in the process.

• verloren = lost
• zoekgeraakt = got lost / went missing

For a package or order in delivery, zoekgeraakt often sounds especially natural because it suggests that somewhere along the way it disappeared or could not be traced.

So zoekgeraakte bestelling is a very idiomatic choice in customer-service language.
