you can run as many campaigns FOR clients in your main account as you wish, if you want clients to have access to a specific campaign you may set a teammate account or sub-account so that they get their own login and can ONLY see the campaigns assigned to them or created within their account!

You'll then have full access to those campaigns and can login to manage them in one-click!

Participants are on a per campaign level so each website WOULD have it's on separate user list for the widgets!"

I bought Tier 3, so if I want clients to have access to specific campaign, I would only be able to do this by setting up teammate or sub-account with limit of only 5 in each? What if I want to increase these limits? I have a base of over 100 clients that can probably benefit from this platform. Also, can the participants option be used for these same purposes?
Thanks.
