Can I view contact emails at the account level?

Can I view contact emails at the account level?

I have thirty-five users in one account.  ten of the thirty-five contacts have received email sent through Zoho.  Is there a way to see all of the emails sent to the contacts at the account level?

I have the same question related to tasks.  Can I view the open tasks for all of the contacts at one specific account, by viewing only the account?

For example in SalesForce, an email sent to a contact is automatically associated with the contact and the account.  An email may also be associated with an opportunity or case.
