Just better email, with AI
Focus mode separates people and anything needing a reply into Primary, while receipts, updates, newsletters, and promotions wait in Everything else.
Replyless reads the full conversation and writes a ready-to-send reply in your tone, which you can make warmer, shorter, or firmer with one tap.
Every incoming email is read and labeled on arrival - leads, invoices, and support requests route themselves, and it remembers your corrections.
Create custom tabs like Clients, Finance, or Payments with sender, domain, or subject-keyword rules, and urgent mail surfaces at the top.
