To Add a Contact to Your Blocked Senders List

How to Block Unwelcome Senders on Mobile Using Clean Email
To block spam emails or unwanted messages from specific senders on your mobile device even more effectively and without opening them, consider using Clean Email. This app offers a simple but effective solution to manage your inbox, and you can try all the premium features for free on your iPhone or Android device.
Instead of searching for an email from the sender you want to block, you can quickly go to the Senders section to take action:
- Open Clean Email on your mobile device and access the menu by tapping the three lines icon in the top left corner.
- Select Senders from the menu.
- Choose the sender you want to restrict and tap Block.
- Optionally, enable the toggle to move all existing messages from that sender to the Trash, then tap Confirm to complete.
What’s more, you can set up rules for entire email domains, which is perfect for when unwanted senders use multiple addresses within the same organization to send you spam emails.
- Go to Auto Clean in the menu and hit Create Rule.
- Name your rule and tap the Any sender or recipients drop-down box.
- Choose Sender Domain from the menu and enter the domain name(s) below.

When enabled, emails from unknown senders are automatically quarantined for your review instead of being delivered to your inbox. You can then decide whether to Allow or Block these senders right from the tool.
How to Block Emails on Outlook for iPad
There’s a dedicated Outlook app for iPad users who prefer the convenience of a portable device but find their iPhone uncomfortable for any reason. It’s very similar to the iOS app, and the blocking process is the same. However, it lacks the advanced inbox management features offered by Clean Email.
That’s why the Clean Email app for iPad can be a great option for iPadOS users. Just like on desktop or iPhone, you can go to the Senders section, review the list of senders who have emailed you, and block any unwanted address directly from the app.
If blocking a single email address doesn't solve the issue, you can create an Auto Clean rule to automatically send messages from an entire domain to the Trash. This ensures that your inbox stays free even from persistent spammers.
Flag Messages As Spam
Sometimes you may not want to block a sender completely, but you also may not want the messages to clutter up your inbox. In such cases, flagging the messages as spam, rather than blocking the sender, can be a worthwhile alternative.
Regardless of what platform you use, you can select the message and then click Move to Junk to clear out the clutter.

Why am I getting unwanted emails in my Outlook inbox?
According to Statista, more than 46% of emails are spam. Like many people, you probably find the influx of this unwanted mail extremely irritating. However, the reasons these messages end up in your inbox are often attributed to multiple factors:
- You subscribed to an email chain. This is a common way for unwanted messages to show up in your inbox. This often happens when buying online, where a hidden checkbox at checkout can lead to numerous newsletters. In such situations, knowing how to unsubscribe from emails on Outlook is essential.
- You put your address out publicly. If your address somehow happens to end up on a public forum or webpage, internet crawlers are sure to get their hands on it and sell that information to other companies.
- A company you subscribed to had a data breach. Unfortunately, it is more common than you might think. When a company’s website data is breached, and they have your details, your mail address, along with other data, can become accessible to unauthorized parties. Learn how to check if you have been pwned and what steps to take in such scenarios.
- You have been a victim of malicious mail in the past. It's not unusual to mistakenly click on a seemingly legitimate message that actually contains harmful content. Interacting with such messages can alert malicious senders of your active inbox, potentially resulting in more intrusive and dangerous messages. To prevent this, learn more about how to stop junk email in Outlook.
Why you should block emails in Outlook
Blocking emails is a common practice, and should be done for the following reasons:
- To remove malicious senders from your inbox. As described above, opening messages from malicious senders can signal to them that your inbox is active, potentially leading to an influx of unwanted and harmful communications from these and other sources.
- Extract unnecessary communication from your inbox. Often, your inbox can become overloaded with irrelevant messages. Blocking senders who contribute to this clutter helps significantly reduce unwanted mail.
- Maintain a clean and organized inbox to stay productive. A crowded inbox can be overwhelming. By blocking non-essential senders, you are closer to achieving 'inbox zero,' which significantly contributes to higher productivity.
Achieve a Clutter-Free Inbox with Clean Email
We've seen how Clean Email can efficiently stop unwanted messages. Let's now explore its other features that help keep your inbox organized and clutter-free.
The Unsubscriber feature is particularly handy for dealing with frequent newsletters and promotional messages. Before blocking, consider unsubscribing from these senders. This feature simplifies the process, allowing you to easily opt out from lists you no longer want, without needing to block the sender.
For emails from unknown senders, the Screener feature is invaluable. It holds mail from new senders separately, giving you the chance to review them before they enter your main inbox. This helps in keeping your email flow organized, giving you control over which mail to accept into your inbox, thereby preventing unnecessary clutter.
The Auto Clean feature is perfect for managing a backlog of mail. It allows you to automatically sort your existing messages, whether by archiving, deleting, or moving them to specific folders. This feature is particularly useful for long-term inbox organization, helping to keep your inbox clean and manageable with minimal effort.
Adjusting Sender Settings provides personalized control, enabling you to manage messages from specific senders on an individual basis. You can set rules to automatically eliminate emails from certain senders, focusing your inbox on the messages that are important to you.
With 33 unique filters in Smart Folders, Clean Email greatly enhances inbox organization. These folders categorize your mail into groups such as ‘Top Senders,’ ‘Online shopping,’ and ‘Finance,’ among others. This categorization makes navigating through your emails much easier, saving you considerable time.
Clean Email not only improves your inbox management but also guarantees the security and privacy of your data. Your information is protected and is never shared, sold, analyzed, or utilized beyond the app's basic functionality.
💡 Note: Outlook offers both an email service (using an @outlook.com address) and an email client that can link with providers like Gmail, Yahoo, AOL, and others. Actions taken in Clean Email apply only to the Outlook service provider, and not to any other email accounts linked with the Outlook email client. You should add each email account you have to Clean Email separately (find out how to add an account here).
Conclusion
Unwanted messages are a common issue for everyone, but there are effective ways to clear your inbox of these distractions. Beyond the various blocking methods available in Outlook, Clean Email provides a suite of comprehensive solutions, making it easier and more efficient to stop unwanted messages in Outlook.
