A: Hi, yes. If you are on tier 10 then you will have 50,000 entries each month. The number of entries and the number of contacts you capture in your campaigns should be the same unless some people enter multiple times to the same campaign or if they enter multiple campaigns. For this reason, the number of contacts could be a bit lower, but not significantly lower. There is no reason to delete your campaigns, as you get unlimited campaigns and the entries will reset each month. Regarding Workspaces, yes. You may switch clients as many times as you want and delete their Workspace every time this happens.
