seeing received emails

Hi,

I've imported leaded into zoho from wufoo, using a CSV file.

If I send an email to a lead,using the ( Godaddy) email account that is linked to my account, I can see the email in their record in the 'emails' section.

However, if they send me an email, I cannot see that.
I can only see what I sent.

Is there a way to see received emails as well.

Many Thanks for any answers.
