For marketing emails: Unsubscribe

Outlook web and the new Outlook app show an Unsubscribe link at the top of legitimate marketing messages. One click and you\'re off the list. Walkthrough: how to unsubscribe from emails on Outlook.

For unwanted senders: Block

Blocking is for legitimate addresses you don\'t want anything from - persistent recruiters, ex-contacts, brands that ignore unsubscribes:

1. Open an email from the sender.
2. Click the three-dot menu at the top of the message.
3. Click Block → Block sender.
4. Future mail from that address goes to Junk.

To block a whole domain (useful when a brand sends from many addresses), open Settings (gear icon) → Mail → Junk email → Blocked senders and domains, and add the domain.

For spam: Mark as Junk

1. Right-click the email and choose Mark as junk, or
2. Click the message and use the Junk button in the toolbar.
3. The message moves to Junk and the sender is added to your Blocked list.

Junk folder mail is auto-deleted after a configurable period (default 10 days), so you don\'t need to clean it manually.

For mass cleanup: Sweep

Sweep is Outlook\'s most powerful built-in cleanup tool. It deletes every message from a sender (or from a specific timeframe) in one click:

1. Open any message from the sender.
2. Click the Sweep button in the toolbar.
3. Choose Delete all messages from [sender], Delete and block future messages, or Always move.
4. Click OK.

For domain-wide problems: Rules

Outlook Rules are like Gmail Filters - they automatically handle incoming mail based on conditions:

1. Open Settings (gear icon) → Rules → Add new rule.
2. Name the rule.
3. Add a condition: Sender address includes → enter the domain (brand.com).
4. Add an action: Delete or Move to a folder.
5. Save.

For volume: bulk unsubscribe

If you have dozens of newsletters to clear out, manual one-at-a-time unsubscribing is too slow. ClearMyInbox connects to your Outlook account, finds every promotional and newsletter sender, and unsubscribes from selected ones in batches. Free for 3 scans.

Use Focused Inbox for everything else

Outlook\'s Focused Inbox sorts mail into "Focused" (the stuff that matters) and "Other" (everything else). Train it by right-clicking misclassified messages and choosing Move to Focused or Move to Other. Over a week or two it gets remarkably accurate, and a lot of unwanted mail stops appearing in your Focused tab without you having to block or unsubscribe.
