Why Outlook makes this harder than it looks
Outlook does show an unsubscribe link above some messages, and it works. The problem is that it works one sender at a time, on one message at a time, so you only ever deal with whoever happens to be at the top of your inbox today. The senders you stopped opening months ago never surface, which is exactly why they keep sending.
Sweep and rules do not fix that either. Both are good tools, and both change what you see rather than what arrives. A rule that files a sender into a folder still lets the mail in, and it quietly stops matching the moment that sender switches sending address, which marketing platforms do regularly.
What in-boxed does instead
Marketing email carries a machine-readable unsubscribe line in its headers, put there by the sender. in-boxed connects to your Outlook, Hotmail or Live mailbox through Microsoft Graph, reads only those headers, and builds one list of every newsletter and marketing sender it finds. You tick the ones you want to keep and it sends the opt-out to all the rest at once.
Where a sender publishes a one-click endpoint, your browser sends the request directly. Where a sender only accepts email, in-boxed prepares a written opt-out request for you to send yourself. Either way it is a real opt-out, so it counts legally: under the GDPR (Article 21) a sender must act without undue delay and within one month at the latest, and under CAN-SPAM within ten business days.
What it will not do is promise a result. Whether a sender actually stops is up to that sender. So instead of a vague success message, you get a list of what went out, what could not be sent automatically, and why.
Read-only, and it stays in your browser
The permission in-boxed requests from Microsoft is delegated and read-only. It covers the fields that identify a sender and its unsubscribe route, and technically excludes message bodies, subject lines and attachments. Nothing is deleted, nothing is moved, nothing is sent from your account.
The scan itself runs inside your browser tab. Your mail and your access token are never sent to our servers, there is no database, and there is no account to create, not even an email address. That is not a promise about our intentions but a property of how it is built, and you can check it: open your browser's network tab while the scan runs and watch where the requests go.
What it costs
Scanning is free and shows you the full list, so you can see how many senders are in there before deciding anything. Unsubscribing from all of them costs €4.99 once. There is no subscription and no renewal, because there is no account to attach one to.
Questions
Kan ik me in Outlook in één keer overal uitschrijven?
Niet met Outlook zelf. Outlook toont per bericht een afmeldlink en werkt dus afzender voor afzender. in-boxed leest de uitschrijfregel die afzenders in hun mail meesturen, toont ze allemaal in één lijst en verstuurt de afmeldingen in één keer.
Welke Microsoft-accounts werken?
Outlook.com, Hotmail en Live werken allemaal, plus werk- of schoolaccounts van Microsoft 365 waarvoor je beheerder externe apps toestaat.
Wat leest in-boxed precies?
Uitsluitend berichtkoppen via Microsoft Graph: de afzender, het antwoordadres en de List-Unsubscribe- en List-Id-regels. De gevraagde toestemming sluit berichtinhoud, onderwerpregels en bijlagen technisch uit.
Verwijdert in-boxed mijn mail?
Nee. in-boxed verwijdert niets en verplaatst niets. De toegang is alleen-lezen. Het enige wat verandert is dat afzenders je van hun lijst halen, waardoor er minder binnenkomt.
Is dit hetzelfde als de knop Opruimen in Outlook?
Nee, en dat verschil is precies het punt. Opruimen verwijdert of verplaatst mail die je al hebt en kan dat blijven doen voor toekomstige berichten. De afzender hoort er niets van en blijft sturen. Uitschrijven stopt het bij de bron.
