How to nicely remind a manager to reply to an important email without being pushy or rude?

Thanks

By send Gentle reminder email

This is when the technology comes in handy. Microsoft Outlook or Exchange has an option to flag the email "response requested" with date and time. So the system will automatically remind thE recipient of the pending response. If you don't have the technology to help, then gently remind the manager asking for response which will help you to complete the task, indicating that the task is pending.

In most cases managers never ignore important emails from their subordinates or employees but in case if the manager dosen't remember , you can remind him politely after a meet up at the cafeteria or after the manager has lunch or probably when the managers mood is good and after he takes a team meeting discussing about the teams improvement.

Do remember to remind him or her only when he is in a good mood.

In simply way, send him sweet reminder or give him call

Just politely ask when u feel that the time is close going to lapse, that plz answer the mail when u had sent to him/her. For no further tension Plz mark CC so that u are out of the entire situation. And this question doesnt arises when u mark CC.

Hi The response is in accordance with the methods provided by the manager as well as indirect methods in case of closing the communication methods
