Reply To Contact Form

Hi Guys,

Happy New Year to you all.

I am following the below video for setting up my Contact Form 7. I have already set it up however the problem i am having is that after completing the form and receiving the email, when i reply to it the message does not get sent.
Is there any settings i need to check to make sure i can reply to the messages once a user has completed my form?
