Deleted emails not showing up in ACCOUNT or CONTACT page anymore?

Hello, new user and have been looking around for this answer.  

If I receive an email from a contact, it shows up on their contact page in the emails sections.

If I delete that email from my mail account, it disappears.  Zoho doesn't store a copy of them email like other CRMs?

Thanks!
