Question regarding domain hosted email

Question regarding domain hosted email

I have a question regarding email hosting.  At my web provider I currently use three emails, for example:
email1@myhost.com
email2@myhost.com
email3@myhost.com

Since I am a small company, all these emails are answered by me.  If I switch my email hosting to zoho, will I have to create three different email addresses in zoho?  For example, will I need to create tree separate log ins to access each email address, or will they all forward to my primary account since I am the only current user?
