Automating activity creation and reminders

Automating activity creation and reminders

Hi - 

I want to be able to automatically create follow-up activities when a sales person contacts a new lead. 

I would like my sales people, when they send an e-mail to a lead in ZohoCRM, they will get an automatic reminder in two days to call them, or it would create automatically a new activity to call the lead in two days.

Is this possible through Zoho CRM or an add-on?
