Inbox Zero

The AI email assistant that sorts your inbox and drafts replies in your voice

Automatic inbox labelling

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.

Pre-drafted replies

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.

Cold email blocking and bulk unsubscribe

Stop cold outreach from ever reaching the inbox, see which newsletters you never read, then unsubscribe and archive them in bulk.

Email analytics

Dashboards reveal who emails you most, which senders dominate your inbox and how your habits change over time so you can act on it.
