How to Mark an Email as Important in Outlook

This article explains how to mark an email as important in Outlook and how to send a high-priority email in Outlook to help you properly utilize these features for effective communication. We also introduce Clean Email as the best tool to keep your inbox organized by automating routine email management tasks.

How Does the Outlook High-Priority Marker Work?

The high-priority marker in Outlook is a feature that allows you to flag an email as important to ensure that it stands out in your inbox. When an email is marked as high priority, it will be displayed with a red exclamation mark next to it, which makes it easier for you to identify and prioritize it among other messages in your inbox.

More importantly, you can also mark an email as high priority in Outlook before sending it, which will indicate to the recipient that the message requires urgent attention. Just know that it's entirely up to the recipient to treat your message with the urgency you believe it deserves. What's more, not all email clients indicate message priority the same, and some don't indicate it at all.

💡 Note: Contrary to popular belief, the high-priority marker doesn't stop emails from going to spam in Outlook because spam filtering in Outlook and other email providers is a separate process that involves a set of algorithms and rules designed to identify and block unsolicited or unwanted emails.

Outlook High-Priority Marker Vs Gmail High-Priority Marker

The Outlook high-priority marker basically says, "Open this message right now! It's really urgent!" The Gmail high-priority markers (the star icon and the yellow Importance marker) are meant to visually signal that a message is important or urgent, but they also teach Gmail which messages it should mark as important automatically next time.

Outlook high-priority messages can be displayed using a smart folder. All Gmail messages that are marked as important using the star icon can be found in the Starred folder, while messages marked as important using the yellow Importance marker can be found under the Gmail Important folder.

💡 Tip: You can star messages from specific senders automatically in Gmail using Clean Email (more about it later in this article), and it takes just one click to set everything up.
