Sickle

Sickle connects every mailbox you own to Claude at once: Gmail and Google Workspace, Outlook and Microsoft 365, iCloud, Fastmail, Yahoo and any IMAP server. Ask Claude what is waiting on a reply across all your accounts, find the invoice from March, summarise a thread, archive newsletters, or draft a reply for you to review. Twelve tools: list accounts and folders, list and search email, read a message or a whole body, mark as read, move, move to Trash, save a draft, and send. Permissions are separate and granted per client when you connect: read (email_read), change (email_change: mark, move, trash, save drafts) and send (email_send). Send is marked destructive, so Claude asks before every send. No tool deletes mail permanently: Trash means your Trash folder. Sickle keeps no copy of your mail. Messages are fetched from your provider for each request, and credentials and email content are not written to logs. You can disconnect Claude at any time at sickle.app under Connect AI; its access ends within the hour. You need a Sickle account with at least one mailbox added at sickle.app (30 days free, then a subscription that also includes the Sickle Mac app). No Mac is required for the connector.
