Overview
This article explains how to reduce promotional, newsletter, and other bulk email in UOmail using Outlook on the web. It also gives guidance for people who send bulk email, so their messages reach the right people and are not treated as junk.
It covers the following topics:
Promotional and bulk email: What it is
Promotional email includes newsletters, marketing messages, sales announcements, and mailing list messages. Bulk email is the broader category of mail sent to many people at once. It is not always spam, and some of it is mail you asked for.
Microsoft automatically filters some bulk email before it reaches you, and bulk messages that look unwanted are often delivered to the Junk Email folder. The tools in this article let you add your own controls on top of that. If you send bulk email, the sender section explains how filtering decides whether your messages reach people.
Note: Bulk mail is different from phishing. If a message looks like it is trying to trick you into giving up a password or personal information, do not click anything in it. Report it as phishing instead. See
Report Suspicious Messages below.

For recipients: Reducing promotional email
These options are available to every UOmail user in Outlook on the web (log in at UOmail with your full UO email address and Duck ID password). Most also work in new Outlook for Windows. Try them in the order listed, from least to most aggressive.
1. Unsubscribe
Unsubscribing is the best first step for mail from a legitimate sender, because it stops the mail at the source.
Option A: Subscriptions page
- In Outlook on the web, select the Settings gear icon.
- Go to Mail > Subscriptions.
- Find the sender you no longer want and select Unsubscribe.
Option B: Unsubscribe banner or link in the message
Outlook may show an unsubscribe suggestion on newsletters, and with Focused Inbox turned on these suggestions appear for messages in the Other tab. You can also use the unsubscribe link in the footer of the message.
Caution: Only use an unsubscribe link from a sender you recognize. For suspicious messages, do not click the link. Use Block or Report instead.
2. Use Focused Inbox to separate promotional mail
Focused Inbox is on by default in UOmail. It splits your inbox into two tabs. Your most important mail is on Focused and most promotional mail ends up on Other, where it is out of the way but still easy to find. If you turned it off and want it back:
- In Outlook on the web, select the gear icon.
- Select the Focused Inbox option so it is turned on.
If an important message lands in Other, open it and move it to Focused. Outlook learns from this.
3. Sweep a sender
Sweep cleans up mail from one sender in bulk, and can keep doing it going forward.
- Select a message from the sender you want to clear out.
- Select Sweep in the top toolbar.
- Choose what you want to do, such as delete all messages from the sender, keep only the latest message, or delete messages older than 10 days. You can also choose to move messages to a folder.
- Choose whether to apply this once or keep applying it to new messages.
To review or edit Sweep rules later, go to Settings > Mail > Sweep.
Note: Sweep does not unsubscribe you. The sender can keep sending mail, and Sweep just routes it. Use Unsubscribe or Block if you want it to stop. Ongoing Sweep rules run about once a day, and you cannot create Sweep rules in classic Outlook, Outlook for Mac, or the mobile apps.
4. Block a sender
Blocking is for senders you did not sign up for. Messages from blocked senders are sent to your Junk Email folder.
- Select the message, then choose Junk > Block sender (or right-click the message and choose Block > Block sender).
- Confirm in the window that appears.
To review or edit your list, go to Settings > Mail > Junk email. You can also add a whole domain there. The sender is not notified that they were blocked.
5. Add a safe sender
If wanted mail keeps going to Junk, add the sender to your safe list.
- Go to Settings > Mail > Junk email.
- Under Safe senders and domains, add the email address or domain.
- Save your changes.
6. Create an inbox rule
Use a rule when you want to keep promotional mail but not in your inbox, for example moving it to a folder called "Promotions" that you check once a week.
- Create a folder for the mail (right-click Folders in the left pane and choose Create new folder).
- Select the gear icon > View all Outlook settings > Rules.
- Select + Add new rule and give it a name.
- Add a condition. For example, From a specific sender, or Subject or body includes a word such as "unsubscribe".
- Add an action, such as Move to your Promotions folder. You can also add Mark as read.
- Optionally add an exception for senders you always want in your inbox.
- Select Stop processing more rules if you only want one rule applied per message.
- Select Save.
Tip: Rules apply to your mailbox, so they work the same on every device you use for UOmail. Review them every few months, since an old rule can quietly hide mail you now want.
Which tool should I choose?
| Tool |
Use it when |
Watch out for |
| Sweep |
You want a fast cleanup of one sender, once or ongoing |
Cannot create Sweep rules in classic Outlook or the mobile apps. Deleted mail is gone for good once Deleted Items is emptied. |
| Rule |
You want mail kept but filed, with conditions you control |
A badly written rule can hide important mail. Start with a narrow condition. |
| Block |
You never want to see the sender in your inbox |
Blocked mail goes to Junk, not away. Easy to forget about if you later want that sender back. |
| Safe sender |
Wanted mail keeps landing in Junk |
Does not override everything. A message can still be caught if it looks like phishing. |
Report suspicious messages
If a message looks like a scam or an attempt to steal your login, do not unsubscribe or reply. Report it using the Report option on the toolbar and choose phishing or junk, then delete it. If you already clicked a link or entered your password, contact the IT help desk right away.
For senders of bulk email
This section is for anyone who sends newsletters, announcements, or promotional messages to many people from a UOmail account. Following these steps helps your messages reach the people who want them, and keeps your account in good standing.
Decide whether email is the right tool
Microsoft does not recommend sending bulk messages from Microsoft 365 mailboxes. Organizations can be blocked for exceeding sending limits, and large mailings from a regular mailbox are more likely to be treated as junk. Before sending, consider these options:
- Small, targeted messages. If you are writing to a small group who all expect to hear from you, a normal email from your mailbox is usually fine.
- UOmail lists and groups. For a defined audience such as a department or team, use a UOmail distribution list or group instead of building your own list from addresses you collected.
- Mailman. Mailman is the UO bulk email service. It uses curated lists to communicate with large groups, so use it for newsletters and large announcements instead of sending from your own mailbox.
Articles on both options are in the Email Lists and Groups category of the knowledge base (see More Information). Some articles in that category require you to log in with your Duck ID.
Tip: If you are not sure which option fits, ask Email and Calendar Help before you send. Fixing a blocked account or a damaged sending reputation takes much longer than a quick question.
Send messages people want
- Send only to people who expect it. Recipients should have signed up, or have a clear reason to hear from you. Do not add people to a list just because you have their address.
- Use a clear sender name and a truthful subject line. People should know who the message is from and what it is about before they open it. Misleading subject lines lead to complaints.
- Keep messages focused. One clear purpose per message. Put the key information near the top.
- Keep your list current. Remove addresses that bounce, and people who have left or asked to be removed.
- Avoid sending the same message repeatedly. Frequent, repeated messages are one of the main reasons people mark mail as junk.
- Do not buy or borrow lists. People on those lists have not agreed to hear from you.
Make it easy to unsubscribe
Every promotional message should give people a simple way to stop receiving it. This also protects you, because a recipient who cannot unsubscribe will often mark the message as junk or block you instead, which hurts delivery for everyone you send to.
- Include a working unsubscribe link or clear instructions in every message.
- Process unsubscribe requests promptly. Marketing email laws such as CAN-SPAM commonly require honoring requests within 10 business days, and sooner is better.
- Do not require people to log in, pay, or give extra information to unsubscribe.
- Do not send further promotional messages to anyone who has unsubscribed.
Note: This article is a practical guide, not legal advice. If you send marketing or fundraising messages, check with your department or campus communications office about requirements that apply to you.
Why bulk messages land in Junk
Microsoft rates messages from bulk senders based on how many recipients complain about that sender. Senders who get a lot of complaints are more likely to have their messages delivered to Junk Email or caught by filtering. These things raise the chance of complaints:
- People marking your messages as junk, blocking you, or reporting them
- Sending to people who did not ask for the mail, or to old lists
- Misleading subject lines or sender names
- No clear way to unsubscribe
- Very frequent or repeated mailings
Recipient actions such as Block, Sweep, and Junk are described in the recipient section above, and they are exactly what your readers will use if your messages are unwanted.
Help your readers find your messages
If you send mail that people have asked for, you can include a short note asking them to add your address to their safe senders so it does not end up in Junk or the Other tab. You can point them to this article, or give these steps:
- Go to Settings > Mail > Junk email.
- Under Safe senders and domains, add your email address or domain.
- Save your changes.
You can also tell readers to check the Other tab if they use Focused Inbox, and to move your message to Focused if it was placed there.

Troubleshooting
If you receive bulk email
| Problem |
What to try |
| I unsubscribed but still get mail |
Unsubscribing can take several days to take effect. If mail continues, block the sender or add a Sweep or inbox rule. |
| I stopped getting mail from a sender I want |
Check Settings > Mail > Junk email for the sender in your blocked list, then check your Junk Email folder, the Other tab, and your rules. If it is still missing, contact IT support. |
| I do not see an unsubscribe option |
Not every message has one. Use the sender's footer link if you trust the sender, or use Block, Sweep, or a rule. |
| Sweep or Subscriptions is missing |
Use Outlook on the web or new Outlook for Windows. Some options are not available in classic Outlook, Outlook for Mac, or the mobile apps. |
If you send bulk email
| Problem |
What to try |
| Recipients say my messages go to Junk |
Review the list above for what raises complaints. Ask readers to add your address to their safe senders, and check that you include an unsubscribe option. If it keeps happening, contact Email and Calendar Help. |
| My messages bounce or my sending is blocked |
Stop sending and contact Email and Calendar Help. Do not keep resending, since that can make the problem worse. |
| People keep asking me to remove them |
Check that your unsubscribe link works and that removals are being processed. Remove them right away. |
| I need to send to a very large audience |
Use Mailman or a UOmail list or group instead of your own mailbox. See the Email Lists and Groups articles, or ask Email and Calendar Help before you send. |
