Non-public topics for Zoho Campaigns

Hello,

I would like to use Zoho Campaigns to email correspondence with investors, but I don't want our regular marketing users to receive the emails or have the ability to sign up for the topic.

Is it possible to create a campaign that is outside of the typical "topic" method? I just want to select a group of contacts and send them an email. I don't want for marketing email contacts to have the ability to subscribe to an investor "topic".
