automatic email after set time/date

automatic email after set time/date

Hello

I have been working with the Zoho system for only a week now, so I am fairly new to it!
I am trying to work out how to get a chain of emails to send - so the first email goes when a contact is added to the Leads, then the second email is automated to send after a set period of time, and another after that. 

Is this something to do with the Autoresponders, or am I looking at the wrong thing???

Look forward to hearing from you shortly
