I wanted to know/ I would like to know

[Maybo]

1. I wanted to know if you will send us the documents before next Friday.
2. I would like to know if you will send us the documents before next Friday.

I’m sending an email to another company. Are the above sentences natural and polite?

They're both grammatically correct. I would say the second is more polite, with "I would like to know". Using any form of "want" in a formal message can come across as abrupt and potentially impolite.

You can also say:

3. Could you let me know whether you will send us the documents before next Friday?

I find the whole message, however it's worded, unnatural.

What are you going to do if they simply reply 'No'?

I will report it to my superior.
How do I make it more natural?

Perhaps:

Please tell us when we can expect to receive the documents. Can you send them before next Friday?

 

[5jj]

before next Friday.

That's rather vague. 'By next Thursday' is better.

Are they supposed to send them by next Friday or is this simply more convenient for you?

If they cannot send them by next Friday, it is fine but we need to make some special arrangements. We don’t want to let them know that we have special arrangements before they reply to our email.

I think we are noving out of the realms of language forums here.

How can you say "We don't want to let them know that" using fewer words?
