ご返事お待ちしておりますって英語でなんて言うの？

It is always important to be more formal when communicating in a business setting.
Therefore always be polite and avoid short requests such as "please respond".

"I look forward to your response", "Please respond at your earliest convenience" and "I hope to hear from you soon" are all excellent ways to ask the receiver to reply to your email.

I hope to hear from you soon. Tells them that you will be waiting for their response.

I look forward to your reply. "Look forward" means you are eager to read their reply.

RSVP..is a traditional French message to please respond.

Another word for response is reply.The above sentences are formal ways to show that you are expecting a reply from them.

"I hope to hear from you soon" is a more informal expression between friends but "I will be looking forward to your reply" is a common expression to use for business emails.

"I await your response" and "I look forward to your response" means the person should reply as soon as possible.

The most common way to politely ask for a reply in an email is to say, "I look forward to hearing from you." However, you can say, "I look forward to your response/reply."

"Please reply at your earliest convenience." - It is very formal and direct. It's completely appropriate in a business email, however, it may come off as too direct or brusque. This is a phrase one should use with discretion as you don't want to put off potential clients or business partners by coming off as too demanding.

A business email requiring a response can be ended by saying either of the following sentences:

We await your reply.
We anticipate your reply.
We look forward to your reply.

I am eagerly awaiting your reply!

"Eager" is a word that native speakers often use and it means that you are strongly expecting or wanting to do something. This indicated that you would like a reply.

"Awaiting" is also often used by native speakers to express that you are waiting for something. In this case, it implies that you are expecting and waiting for a reply.

In conclusion, this answer indirectly suggests that you are expecting (or want) a reply and that you will wait to hear back from the person.

I hope to hear from you soon.

This is answer is very similar to the first one as it is expressing your hope to receive a reply from the person. This is also a very commonly used phrase for native speakers.

Please contact me at your earliest convenience.

"Convenience" is a term that native speakers use very often. It simply means that it fits well with the person's needs and life.
In conclusion, this answer differs from the previous two, because this time you are directly asking the person to respond to your email as soon as they can.

I look forward to hearing from you.
I look forward to hearing you thoughts on this.

I think these are subtle ways of asking for a reply, which is usually the better way to be, subtle, especially when it comes to email communication.

I hope this helps.
Have a great day.
Will

When native speakers want to say that they want someone to respond to an email/phone call/etc, they use a combination of the phrasal verb "to look forward to" and the noun "a response." "To look forward to" means "to hope for" or "to be excited for" and "a response" is the person's answer to your call/email/ect.

EX)
Thank you for your time and I look forward to your response!

All of these can be used in a formal email when you want the reciever to reply.

If you are in need of an urgent response you could say 'Please get back to me at your earliest convenience.' - This means, please get back to me as soon as possible.
