Agentys: From Filter to Full Inbox Handler

Switching from SaneBox to Agentys

SaneBox is a reliable inbox filter, but filtering is only half the problem. Agentys combines AI-powered sorting with overnight reply drafting in your voice, saving 10+ hours per week instead of just 20 minutes. If you want a true inbox handler and not just a sorter, try Agentys. One honest caveat: Agentys needs about a week of sent-history analysis before drafts hit their stride.
