The AI email assistant that sorts your inbox and drafts replies in your voice
Incoming mail is sorted into categories like To Reply, Newsletter, Cold Email, Calendar and Notification as it arrives, using default rules or categories you define yourself.
Emails that need a response get a draft written in your tone and referencing your real calendar availability and CRM context, ready to review and send.
Stop cold outreach from ever reaching the inbox, see which newsletters you never read, then unsubscribe and archive them in bulk.
Dashboards reveal who emails you most, which senders dominate your inbox and how your habits change over time so you can act on it.
