We are often faced with situations where the other party is not responding, either in business and personal settings. Examples could include from hearing back for next steps after an interview or a business prospect ignoring your emails.
This gets annoying quickly, as we start questioning our communication ability and become anxious. One quick trick I have found after reading the book “Never Split the Difference” is to send a short email as below:

“Have you given up on this project?”

This “No”-oriented question that suggests that you are ready to walk away, works wonders.

You can make minor changes to the email or message to accommodate different setting.

Cheers!
