Saving email addresses

Hi, Im trying to save email addresses into Zoho so that when i type up a new email Zoho will recognise the email address and input it in for me (this was automatically done with my Yahoo.account). Currently I have to manually type in the email address each time i want to send an email. Even if i have used that email address before. Is there a way soho can save each new email address used?
