Take Control of Your Outlook Inbox With Clean Email

Knowing how to unblock email in Outlook isn’t the only advice you need to maintain a clean and healthy mailbox. Thankfully, Clean Email can help you block emails in Outlook or unblock them as well as do many other things to manage your mailbox.

For instance, the Auto Clean feature (which helps you unblock entire domains) lets you set up automated rules for your mailbox. With Auto Clean, you can program Clean Email to delete messages after a specified period of time, transfer messages to specific folders automatically when they arrive, and more. These “set it and forget it” rules can make day-to-day mailbox management so much easier.

Also, the Unsubscriber feature helps remove you from promotional messages you do not want to receive. This removes even more clutter from your inbox without you having to go through the hassle of blocking each sender’s address individually. Instead, you simply press Unsubscribe to remove yourself from these subscription lists and the app will do the rest.

Similarly, Sender Settings lets you automatically block messages from specific senders. This feature works like unsubscribing, but with individual email addresses instead of whole domains or subscription lists.

Other tools, like Screener filter emails from new unknown senders into a quarantined folder instead of your main inbox. You can review them to make a decision if this is a legitimate sender and if these emails can be moved to your inbox. Otherwise, you can send them directly to the Trash folder.

Then, the Smart Folders tool lets you glance at messages’ groups based on specific criteria, like the topic of messages (e.g. ‘finance’, ‘travel’, and more). These groups serve like preset filters to simplify searching and managing your emails.

All of these tools, and others, make Clean Email the ultimate email management app for anyone who wants to keep their Outlook inbox organized and safe. The app is completely safe to use, and the company will never collect or sell your data.

💡 Note: Outlook offers both an email service provider (meaning you use an mail address) and an email client (which links with other mail providers like Gmail, Yahoo, or AOL). Because of the way these each work, any actions you perform in Clean Email only translate to the email service provider, which means that they may not show up if you use the Outlook email client.
