Don't want new email recipient to pick up under Leads module

Don't want new email recipient to pick up under Leads module

Hi Zoho CRM

I really like that Zoho CRM picks up emails from my gmail account. 

However, I don't want emails from new contacts (that I haven't entered into Zoho CRM otherwise) to automatically go under leads, as I would like my leads module as clean. This will make managing my leads much easier. 

Any suggestions? 

Thanks for a great product.
