Both ので and から can mean because, but ので usually sounds a bit softer, more explanatory, and more neutral.

• 重いので = because it’s heavy
• 重いから = also because it’s heavy, but can sound a little more direct or personal

In this sentence, ので fits well because the speaker is calmly giving a reason for the action that follows.

は marks 小包 as the topic: as for this package...

So the sentence is structured like:

• この小包は重い = This package is heavy
• and because of that, the speaker will have the delivery person come pick it up.

If you used が, it would focus more directly on the package as the thing that is heavy. With は, it feels more like the package is the topic under discussion.

配達員 means delivery worker / delivery person.

Adding さん makes it more polite and respectful:

• 配達員 = delivery worker
• 配達員さん = the delivery person

Japanese often adds さん to occupations or roles when referring politely to someone, especially in everyday conversation.

In 〜てもらう constructions, the person who does the action for you is often marked with に.

So:

• 配達員さんに来てもらいます = I’ll have the delivery person come / I’ll get the delivery person to come

Here, に marks the person from whom the speaker receives the favor/action.

まで means as far as, until, or to in the sense of a limit or endpoint.

So:

• 家まで = to the house / as far as my house

In this sentence, it shows the destination of the delivery person’s coming.

It is slightly different from just 家に, which only marks the destination. 家まで emphasizes the endpoint: all the way to my house.

This is a very common Japanese pattern:

• verb stem + に
  • 来る = come to do ...

Here:

• 取る = to take
• verb stem = 取り
• 取りに来る = come to take, or more naturally here, come pick up

So:

• 取りに来て = the te-form of 取りに来る
• It connects to もらいます

Altogether:

• 取りに来てもらいます = I’ll have someone come pick it up

The object is omitted because it is already understood from context.

Earlier in the sentence, we have この小包 (this package), so Japanese does not need to repeat it.

In English, we would often say pick it up. In Japanese, once the object is obvious, it is very natural to leave it out.

If you wanted to say it explicitly, you could say something like:

• この小包を取りに来てもらいます

But leaving it out is perfectly normal.

〜てもらう means to receive the favor of someone doing something, or more naturally:

• have someone do something for you
• get someone to do something for you

So:

• 来てもらいます = I’ll have them come
• 取りに来てもらいます = I’ll have them come pick it up

This does not mean the speaker physically forces the person. It usually means the speaker arranges it, asks for it, or benefits from that action.

Historically and grammatically, yes, it comes from もらう meaning to receive. But in a sentence like this, it is better understood as:

• receive the favor of
• have someone do
• get someone to do

So instead of translating word-for-word as I receive the delivery person coming to pick it up, English naturally says:

• I’ll have the delivery person come pick it up

Because the sentence is not just saying the delivery person comes. It is saying the speaker is arranging for that person to come for the speaker’s benefit.

Compare:

• 配達員さんが家まで取りに来ます
  = The delivery person will come to the house to pick it up

• 配達員さんに家まで取りに来てもらいます
  = I’ll have the delivery person come to the house to pick it up

The second version includes the idea that the speaker is requesting or arranging this service.

もらいます is in the non-past polite form. In Japanese, the non-past can refer to:

• present/habitual actions, or
• future actions

In this sentence, it refers to a future plan or decision:

• I will have the delivery person come pick it up

So even though it is not marked with a separate future tense, the meaning is future from context.

Yes. Japanese often leaves out words like my, your, or our when the meaning is clear.

Here, 家まで naturally means to my house because the speaker is talking about arranging a pickup.

So although the sentence literally just says to the house/home, English usually translates it as to my house or to my home.

Yes, very common. It combines two useful patterns:

1. verb stem + に + 来る
   = come to do something

2. te-form + もらう
   = have someone do something for you

So once you know those patterns, this sentence becomes much easier to understand.

Some similar examples:

• 見に来る = come to see
• 迎えに来る = come to pick someone up
• 手伝ってもらう = have someone help you
• 迎えに来てもらう = have someone come pick you up

This sentence follows that same logic.
