ConvertKit alternative for inbox triage
ConvertKit, now Kit, is a newsletter platform. It sends email to your audience and it does that well. It was never built to read the email coming back at you, which is where brand deals, sponsorship pitches and the daily noise arrive. Cleanbox is built for exactly that inbox: it sorts it, drafts replies in context and passes qualified deals to DM Concierge.
