请在本周三之前反馈信息 英文怎么说？非常感谢

Your kind feedback to me before/by Wednesday would be highly appreciated.
这个是非常正式的商业用语。

如果关系稍好点，就可以用：
Please kindly get back to me by/before Wednesday.
Please give me your kind response by/before Wednesday.
Please response me back by/before Wednesday.
Please give me your kind feedback by/before Wednesday.

希望我的回答能够帮助你，谢谢采纳！

Please feedback before wednesday.

please feedback the information before Wednesday.

Please get back to me (with the feedback) by Wednesday.
星期天之前，英语是by Wednesday
get back to me就有反馈信息的意思

Please feedback information on Wednesday before.

Return your feedback information before this Wesdnesday, please.
