We are looking for a new helpdesk solution and already use Zoho CRM.

Is there any way to sync all converstion activity with Gmail? So, 

1) New email in Gmail = new ticket (presume yest)

2) Response from Zoho Support = email sent from gmail to customer

3) Customer response to our response = email in from gmail

We need this as we have software which saves all our communications in gmail to client files, and want the Support tickets to sync likewise.

Thanks
