I then went here-  https://mail.zoho.com and started an email template with things set up the way I wanted them to be. 

Since I do NOT want the people I'm emailing to be able to see everyone else's emails, I'm sending the email to myself as the "to" and in BCC I selected "custom category". 

Now, there are 2 emails in this list so far. But adding the category to the BCC list only adds ONE email/contact. 

When I click to add the category list to the BCC text box, I want ALL of the contacts from that category to be added.

What am I doing wrong? How can I make it do this?
