Your privacy
What Sender Sweep can and can't access
It can
- See who sent each email, when, and whether you've read it. The sender ranking is built from that.
- Show the subjects of a sender's recent emails when you open that sender.
- Read a newsletter's headers to find its unsubscribe link.
- Move emails to Deleted Items or Archive, or mark them as read, but only when you click.
It can't
- Send email as you. It doesn't ask for that permission.
- See your Microsoft password. You sign in on Microsoft's own page.
- Read the text of your emails. Message bodies are never downloaded.
- Store your email. Scanning runs in your browser, not on our servers.
When you sign in, Microsoft asks you to approve two permissions: User.Read (your name and email address) and Mail.ReadWrite (to read and move messages). That permission covers more than Sender Sweep uses; the lists above are what the app actually does. You can remove its access anytime at account.live.com/consent/Manage. More detail: how Sender Sweep keeps your email private and Outlook app permissions explained.
Compared
Sender Sweep vs Outlook's Sweep
| Feature | Outlook's Sweep | Sender Sweep |
|---|---|---|
| Senders at a time | One | Hundreds at once |
| Shows who emails you most | No | Yes, ranked by volume and read rate |

Sender Sweep is an independent app, not part of Outlook. For a few known senders, Outlook's own Sweep is enough: here's how Outlook's Sweep works.
Frequently asked
Does my email get sent to your servers?
No. All mailbox scanning and cleanup happens in your browser, talking directly to Microsoft Graph. Our backend only ever sees your plan and usage counts, never your email.
Is Sender Sweep made by Microsoft?
No. Sender Sweep is an independent app that connects to your mailbox through Microsoft's official Graph API. It isn't Outlook's built-in Sweep feature, and it isn't affiliated with Microsoft.
Which accounts does it work with?
Personal Microsoft accounts: Outlook.com, Hotmail, Live, and MSN addresses, including Microsoft 365 Personal and Family. Work and school accounts aren't supported yet. You sign in with Microsoft, so there's no separate password.
Is deleting safe? Can I undo it?
Yes. Delete moves messages to your Deleted Items folder, exactly like Outlook's own delete button. To undo, open Deleted Items and move them back. They stay there for 30 days, or until you empty the folder.
How do I remove Sender Sweep's access to my mailbox?
Go to account.live.com/consent/Manage, find Sender Sweep in the list of apps you've given access to, and remove its permissions. Nothing runs in the background, so if you simply stop using the app, it stops reading your mailbox.
Does it work on my phone?
Yes. Sender Sweep is a web app, so it runs in your phone's browser with nothing to install. A computer's bigger screen is handier for large cleanups.
What's free vs Pro?
Free includes unlimited scanning and analytics, plus 500 deletes and 5 unsubscribes each month. When you reach a limit, you can keep browsing your senders: the limit resets the next month, or Pro ($29/year) removes it.
