"I would have meant to ask you for your comments on the idea but I appriciate your UAT test". The word comments is wrong. It should be 'opinion'. Example: " I would like to know your opinion about my idea" comments are for something different.

I ment to ask you for your comments on the idea ............ Is it correct ? Not do it correct

Comment is fine. I disagree with ‘opinion’ comment. ( this is an example of my opinion) Comment is more objective, you are asking for remarks. ( just like sport commentators) Opinion is a judgement or belief- it is more subjective. Eg my opinion is that it’s not interesting. 2. There is no reason to explain in the email what was the intention of your original message. Simply write: I would like to know your opinion in regard to the idea that I have described. Or I would really appreciate if you could write a comment regarding this idea; ( polite) Could you please comment on this idea ( less polite) I would be very interested in knowing your thoughts regarding this idea. P.S if you want them to give you beneficial comments, be specific. Could you please descibe what you specifically like/ dislike/ think about XYZ. Hope it helps.

I meant you to give your advice on the idea and never thought you have done it. Thanks for your support.
