Hello. I'm new to using Zoho. I have a client (Chimacum Grain) that I work for and I made them a Squarespace website. They needed to get a domain name and professional email, so I set that up for them with Zoho.

Now, I'd like to do the same for another client of mine (Fillmore Street). They need professional email and email campaigns. I tried to create a new account, but my email address is already associated with the Chimacum Grain account. I'm not sure how to create a separate account for Fillmore Street. I suppose I could use a different email address to set this one up, but that doesn't seem like a long-term solution. I will likely be setting up other clients on Zoho as well and I want to be able to manage them all from one place, without them being able to see each others' information. Is this possible? 

I'm confused as to how to proceed. thanks for your help,

Sarah
