Tủ lạnh còn tốt; hóa đơn tiền nước trong email.

Vietnamese often leaves out the verb to be when English would require it.

• Tủ lạnh còn tốt = The fridge is still good
• Hóa đơn tiền nước trong email = The water bill is in the email

This is very normal in Vietnamese, especially in short statements, notes, texts, and listing-style language.

If you translated word-for-word, it would look more like:

• fridge still good
• water bill in email

Vietnamese relies a lot on context, so the meaning is understood without adding a verb like is.

Còn often means still / remaining, and tốt means good.

So còn tốt means:

• still good
• still in good condition
• still works well

With an object like tủ lạnh (fridge), it usually suggests the item has been used but remains in good condition.

Examples:

• Máy giặt còn tốt = The washing machine is still good
• Xe này còn tốt = This vehicle is still in good condition

It is a compound noun phrase:

• hóa đơn = bill / invoice
• tiền nước = water fee / water bill amount
  
  • tiền = money / fee
  • nước = water

So hóa đơn tiền nước means the water bill.

A very literal breakdown would be:

• invoice + water payment

This pattern is common in Vietnamese:

• hóa đơn tiền điện = electricity bill
• hóa đơn tiền mạng = internet bill
• tiền nhà = rent / house payment

Trong means in / inside, and email here refers to an email message or email communication, depending on context.

So hóa đơn tiền nước trong email most naturally means:

• The water bill is in the email
• The water bill is in the email message
• possibly The water bill was sent by email, depending on context

In short everyday Vietnamese, people often use email a bit broadly. A fuller version might be:

• Hóa đơn tiền nước ở trong email.
• Hóa đơn tiền nước đã gửi qua email.

But the shorter version is common in casual writing.

Yes. It sounds like telegraphic Vietnamese—the kind of short, efficient language used in:

• texts
• notes
• item descriptions
• marketplace listings
• quick replies

A fuller version might be:

• Tủ lạnh còn tốt; hóa đơn tiền nước ở trong email.
• Tủ lạnh vẫn còn tốt; hóa đơn tiền nước đã được gửi trong email.

But Vietnamese often drops words that are easy to infer.

So the original sounds natural if the speaker is being brief.

The semicolon separates two short related pieces of information:

• Tủ lạnh còn tốt
• hóa đơn tiền nước trong email

It works like a stronger pause than a comma. In English, this could be similar to:

• The fridge is still good; the water bill is in the email.

In casual Vietnamese writing, punctuation can be flexible. You might also see:

• a comma
• a period
• two separate lines

Especially in messages or listings, the exact punctuation is less important than the information itself.

Yes. Email is very commonly used in everyday Vietnamese.

You may also see or hear:

• imeo in very informal speech/spelling
• thư điện tử as a more formal or native-Vietnamese equivalent

But in normal modern usage, email is completely standard.

Examples:

• Gửi qua email nhé. = Send it by email.
• Mình đã nhận email rồi. = I already received the email.

Vietnamese does not use articles like a / an / the the way English does.

So:

• tủ lạnh can mean a fridge, the fridge, or fridges depending on context
• hóa đơn tiền nước can mean a water bill or the water bill

Context tells you which one is meant. In this sentence, the meaning is probably definite:

• the fridge
• the water bill

That is very normal in Vietnamese.

Yes, but there is a slight nuance difference.

• còn tốt = still good / remains good
• vẫn tốt = still good too, but often feels a bit more neutral or general

For a used item, còn tốt is especially common because it suggests the item has not deteriorated too much and is still usable.

Compare:

• Tủ lạnh còn tốt = The fridge is still in good condition
• Tủ lạnh vẫn tốt = The fridge is still good

Both are understandable, but còn tốt feels very natural for describing condition.

You might see it more often in writing than hear it exactly like this in full conversation.

It sounds especially natural in:

• text messages
• sales posts
• rental discussions
• quick notes
• checklist-style communication

In spoken Vietnamese, people might say something a little fuller, such as:

• Tủ lạnh còn tốt. Hóa đơn tiền nước ở trong email nhé.
• Tủ lạnh vẫn còn tốt, còn hóa đơn tiền nước thì ở trong email.

So the original is natural, but it has a concise, note-like style.
