La tarifa postal incluye el franqueo y el acuse de recibo.

In Spanish, descriptive adjectives usually come after the noun, especially in neutral, factual language.

• la tarifa postal = the postal rate / postal fee

So postal works like a descriptive adjective here, similar to:

• servicio postal
• código postal

Putting postal before the noun would sound unusual in this kind of standard expression.

Not exactly.

• tarifa usually means a rate, fee, or set charge
• precio is the more general word for price

So tarifa postal suggests an official mailing fee or postal charge, not just any random price.

For example:

• precio del libro = price of the book
• tarifa postal = postal rate
• tarifa de envío = shipping fee

Incluye is the third-person singular present tense of incluir.

• incluir = to include
• incluye = includes

It matches the subject la tarifa postal, which is singular.

A quick pattern:

• yo incluyo
• tú incluyes
• él/ella/usted incluye
• nosotros incluimos

So:

• La tarifa postal incluye... = The postal rate includes...

Because Spanish often does not use subject pronouns when they are unnecessary.

In English, you must say:

• The postal rate includes... or
• It includes...

In Spanish, the subject is already clear from the noun phrase:

• La tarifa postal incluye...

You could replace la tarifa postal with incluye... only if the context already makes the subject obvious.

Franqueo specifically refers to postage or the amount paid to mail something.

It is more specific than envío.

• franqueo = postage
• envío = shipment / sending / delivery

So in a postal context:

• franqueo is the money or postal payment required
• envío is the act or shipment itself

That is why franqueo is the better word here.

Yes, acuse de recibo is a set phrase in formal Spanish.

Literally, it is something like:

• acknowledgment of receipt

In real usage, it refers to a service showing that the item was received, often similar to:

• return receipt
• proof of delivery
• acknowledgment of receipt

It is common in postal, legal, and administrative contexts.

You should learn it as a chunk:

• acuse de recibo

Yes, it is related historically to acusar, but in this expression it does not mean to accuse in the everyday English sense.

Here, acuse is a noun used in formal language, meaning something like:

• acknowledgment
• notice
• confirmation

So acuse de recibo has nothing to do with accusing someone. It is just one of those cases where a related form developed a specialized administrative meaning.

Because Spanish often repeats the article with each noun in a list, especially when the items are distinct things.

• el franqueo y el acuse de recibo

This is very natural Spanish.

You will often see:

• la casa y el jardín
• el precio y la calidad
• la fecha y la firma

Sometimes Spanish can omit a repeated article, but here using el twice is the most standard and clear option.

Because de here links two nouns in a general way: acknowledgment of receipt.

• acuse de recibo = acknowledgment/proof that something was received

If you said del recibo, it would sound like of the receipt in the sense of a specific receipt document, which is not the intended meaning here.

So:

• de recibo = receipt as a general concept
• del recibo = of the specific receipt

Because these are direct objects that are things, not people.

The personal a in Spanish is normally used before a specific person (and sometimes pets or personified beings).

Examples:

• Veo a María.
• Llamo a mi profesor.

But here:

• incluye el franqueo
• incluye el acuse de recibo

These are things, so no a is used.

Yes, it sounds fairly formal or administrative.

Words like:

• tarifa postal
• franqueo
• acuse de recibo

are common in official, postal, or business language.

In everyday conversation, someone might choose simpler wording depending on context, but this sentence sounds perfectly natural in notices, forms, service descriptions, or postal explanations.

In most Latin American pronunciation, incluye sounds approximately like:

• in-KLOO-ye

The y sound here is like the y in yes for many speakers, though in some regions it may sound a bit stronger, closer to j in judge or zh in measure.

Stress falls on clu:

• in-CLU-ye

A helpful approximation is:

• fran-KEH-o

The stress is on que:

• fran-QUE-o

Also:

• qu before e gives a k sound
• so franqueo is not pronounced with an English kw

It is more like:

• fran-KEH-oh

In meaning, yes, often you can.

• tarifa postal = postal rate
• also sometimes mailing rate or mail rate, depending on context

But in Spanish, postal is the normal adjective in formal phrases related to the postal system:

• servicio postal
• dirección postal
• tarifa postal

So even if English might prefer mail in some contexts, Spanish commonly uses postal.

Grammatically, maybe, but incluye is the better choice.

• incluye = includes
• contiene = contains

For prices, fees, services, and plans, Spanish usually prefers incluir:

• El precio incluye impuestos.
• La tarifa incluye envío.

Contener is more often used for physical contents:

• La caja contiene documentos.
• La botella contiene agua.

So incluye is the natural verb here.
