What should I write in a reply e-mail whenever I got it from my boss or co-workers? I'd like to express that I've received their information.
I always write "Yes!!" or "Received!!". But it seems a little strange.
Are there any other proper expressions?
Unless the person says "Please let me know when you read this, so we can talk about it" or something like that, to respond to every e-mail is NOT a good idea. And if you do need to respond, do not use an exclamation mark, and certainly do not use two of them.
Something like "Okay, thanks for sending this. It's really helpful." if it's helpful information or "I'll add this to my task list and let you know when it's complete" if it's a request to do something might make sense, depending on the context.
"Received with thanks" or "Noted with thanks."
I see where you're coming from. I'm also one of those who always need to confirm receipt of emails or documents sent to me as I work as a freelance translator and all the jobs are sent via email.
What I usually write is something like:
Just a quick note to let you know that I have received the (document/email/message/etc) and will (send the translation back to you as scheduled/look into this right away and get back to you/etc etc etc).
Generally speaking, I don't see why you need to send any acknowledgement at all. Did someone tell you that you had to do this? It seems to me that you are just cluttering up their inboxes with unnecessary emails.
Do they then send an acknowledgement that they have received your acknowledgement?
