A worked example: $1,000 a month
At $9.99 with no tips or PPV, $1,000 net needs roughly 125 subscribers. Add average tips of $4 and PPV of $8 per subscriber — unspectacular, mid-pack numbers — and the same $1,000 needs 57. That is the whole argument for working the inbox: engagement halves the audience a goal requires. Set your own numbers above and watch the required subscriber count move.
