Focus Mode ## The five biggest changes 1. **Focus Mode and Triage.** Email sorts every mailbox into To-dos, Needs your reply, Catch up and Clean up, and Triage works through the rest one email at a time. See [Email](/comms/email/overview). 2. **Peek.** Click a record or page and it opens beside the screen you're on. See [Peek](/surfaces/records/peek). 3. **Single sign-on.** Your team signs in with the accounts they already have from your identity provider. See [Users](/team/users/overview). 4. **Campaigns.** Send an email to everyone on a list, personalized with merge fields, with permissions on who can send. 5. **A rebuilt mobile shell.** A tab bar for Mail, Convos, Home, Calendar and Library, with Search and Ask Stella on every tab. See [Mobile app](/start/apps/mobile). ## Also this month * **Daily brief**: a morning brief and end-of-day recap on Home, by push or email. See [Daily brief](/ai/daily-brief). * **Stella**: previews automations and whole pages before it builds them, and answers over SMS. See [Dashboard preview](/ai/dashboard-preview). * **Webhooks**: 19 event types, retried over 24 hours. See [Webhook events](/dev/webhooks/events/overview). * **Plan usage**: see how much of each plan limit your workspace has used.
