nylas email subscriptions list discovers subscriptions from standard List-Unsubscribe headers across the active grant’s mailbox and reports the sender, List-ID, message count, and last-seen time for each one.
nylas email subscriptions unsubscribe previews the matching subscriptions and opens their HTTPS or mailto: unsubscribe action in your browser or mail client for review. It never submits a one-click unsubscribe request automatically from untrusted message headers.
nylas email subscriptions cleanup moves messages that match a subscription to Trash, or permanently deletes them with --permanent, independently of the unsubscribe step so it can be retried on its own.
Common flags across the three commands include --since, --limit, --all-folders, --dry-run, and --yes.
Google and Microsoft grants are supported, since Nylas exposes the original headers these commands rely on. EWS and IMAP-backed grants aren’t supported yet.
