| Core approach | PublishedA guided sender-by-sender cleanupRank senders, inspect the effect, then choose Keep, Archive, Unsubscribe, Later, or Delete. | NativeNative lists and search actionsManage subscriptions lists active subscription senders with recent-email counts and unsubscribe; search plus select-all handles bulk moves. |

| Mailbox support | LimitedGmail and Google WorkspaceDeclutrMail is intentionally Gmail-specific today. | NativeGmail and Google WorkspaceBuilt into the mailbox itself; nothing to connect. |
|---|
| Existing-mail cleanup | PublishedYes — by senderArchive, Later, and Delete act on matching current inbox mail. Unsubscribe does not move existing mail. | NativeSearch + select-all bulk actionsNative search finds current matches, select-all shows the selected-conversation count, and bulk actions move them; there is no per-sender preview of the planned label changes. |
|---|
| 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. | LimitedVia filters, built separatelyManage subscriptions does not create rules; ongoing routing means composing Gmail filters yourself. |
|---|
| 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. | NativeNative unsubscribe on detected sendersGmail offers unsubscribe on messages and in Manage subscriptions for senders it detects as 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. Unsubscribe is not a reversible DeclutrMail action. | LimitedSelection count and brief Undo; no long-term action historyBulk changes show the selected count and a brief Undo; archives stay recoverable in All Mail and deletes in Trash for about 30 days. There is no long-term record for each action or multi-day undo window. |

| Email-data posture | PublishedListed Gmail details, including the preview snippetFull message bodies and attachments are not fetched. | NativeNo additional vendorCleanup happens inside the service that already hosts the mailbox. |

| Public starting point | PublishedFree, $9 Plus, or $19 Pro monthlyFree includes 50 cleanup actions per month. Plus is $90/year; Pro is $190/year, with a limited $129 founding offer in the current tier manifest. | NativeIncluded with GmailNo separate purchase; Google notes Manage subscriptions is gradually rolling out and may not be available to every account yet. |
