Give Claude access to Spark - read, draft, triage, and act on your email, calendars, meetings, and contacts.
What Claude can do:
- Search and browse your emails across all connected accounts
- Read full threads with bodies and attachments
- Read individual attachment contents directly (images, PDFs, text files)
- List folders and shared inboxes
- Look up contacts
- Check calendar events and find free time slots for scheduling
- Review meeting transcripts, summaries, and notes
- Show team info, members, and assignments
- Compose drafts - new messages, replies, forwards, with attachments
- Post team chat comments on shared threads
- Triage messages - archive, pin, snooze, move, label, mark as done, share with team, assign and delegate
- Reclassify smart categories (Priority, People, Notifications, Newsletters)
- Manage contacts - block/accept, change category, mark important/primary, toggle auto-summary
- macOS or Windows with a recent build of Spark Desktop, signed in to at least one account.
- Spark CLI enabled: in Spark, go to Settings → AI Agents → Spark CLI Setup and follow the prompts.
- Per-account access levels -
read-only,triage(everything in read-only plus drafts, comments, and email/contact actions), orsend(everything in triage plus sending mail and calendar invitations) - configured in Settings → AI Agents -> Spark CLI Access. Recipes and personas declare the level they need; running one against an account with insufficient access returns an error explaining how to upgrade.
