“convert to people for me are worth about eighty dollars per subscriber but somebody on active campaign is worth about like five right so I that tells me like either converted people have a lot more disposable income and they really like what I'm doing versus active campaign or I'm dropping the ball with them”

Wire your ESP + Stripe data into a tool like SegMetrics so you can break average subscriber value down by every survey attribute. A 16x value gap between two segments (ConvertKit $80 vs ActiveCampaign $5) is a flashing sign of a missing product, not a coincidence — Brennan's new beginner segmentation course came directly from spotting exactly this gap.
