You have your organic and paid channels in place and the flow is like;
You create a message, post or push it through channels. The channels give impressions to your messages.
The impressions could be paid or on the opportunity cost (organic). Then it serves traffic (heterogeneous) to the product. They may signup for the trial or not.
Still, you get charged on the basis of CPC or CPC either for new or repeat users with different email addresses created just to avail of free trials.
The traffic then signups for free-trial (activation).
Then you get subscribers (25%-30% of the free-trial signups) converted after activation.
