For this when you add the shortcode in the contact page for the form make sure you are adding the email field and enabling the validation of the email, refer:

Hi Latiyan:
Thank you for your reply. For some reason I did not get an email about your reply, so I didn't realize you had answered.
Yes, I have done everything as per your instructions and the link you provided.
The form works fine, the email gets sent and I receive it.
However, there is no sender on the email. It says "No Sender" and the field is blank. There is no email associated with it. We want it to say it was sent from a particular address.
How can we do that.
Please go to wp-admin->settings->general->email address, and check if there is an email address present.
Also go to wp-admin->lms->settings->emails, and check if you have entered the senders information or not.
Let me know if this helps.
