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.
AI-assisted email and SMS marketing that turns audiences into customers
Drag-and-drop templates, reusable layouts, and guided steps to design and send newsletters or promotional emails without a designer.
Build automated journeys triggered by signups, purchases, birthdays, or inactivity, including welcome and abandoned-cart series.
Generate draft copy and subject lines, and use data-driven send-time suggestions to improve engagement.
Tag, segment, and filter contacts, and track engagement history in a searchable audience database.
