Should you build this?
People with years of old email pay to make it disappear. The opening is that cleanup is a one-time job billed like a subscription: Mailstrom meters the backlog at $59.95-$199.95/yr, Clean Email's free tier stops at 1,000 messages, and SaneBox's Email Deep Clean is bundled into an ongoing subscription rather than sold once. This is not proven and no claim here is a promise of revenue. The risk is real: Gmail gives away bulk delete, free tools like Unroll.me and Cleanfox clean at $0 by monetizing inbox data (the FTC's Unrollme case page confirms a settlement over how it accesses and uses personal emails), and Mailstrom's own competitor page claims SaneBox does not touch the backlog, though SaneBox's documentation contradicts that. The one-time model must therefore win on privacy and unlimited accounts, not just price.
