| Future-mail automation | LimitedSeparate Autopilot rulesAutopilot rules are configured separately — you preview a rule before turning it on, and it then acts on future matches, or collects them for your batch approval if you choose Watch first. A one-time Archive or Later action does not automatically become a future-mail rule. | NativeCore behaviorFilters can label, archive, delete, star, or automatically forward matching incoming mail. |

| Unsubscribe | LimitedWhen the sender provides an unsubscribe methodRFC one-click requests can run directly. Mailto-based requests require a manual step; unsupported senders stay explicit. | LimitedSeparate Gmail subscription controlsA filter routes mail; it does not itself opt out. Gmail separately offers Unsubscribe and Manage subscriptions. |

| Preview and recovery | LimitedRecorded in Activity when recovery is availableArchive, Later, and Delete use the 30-day Activity Undo window. Delete also has separate Gmail Trash recovery, normally up to 30 days.
