Marking emails as read is a quick solution, but doing it manually can take time, especially with a large number of messages.

What is Outlook and Why is it Useful?
Outlook is a popular email management platform developed by Microsoft. It's designed to streamline communication and organisation for both personal and business use.
Here are some key reasons why Outlook is useful:
Email Organisation: Organise your inbox with custom folders and filters to sort emails based on priority and relevance.

With Outlook, users can manage emails, calendars, contacts, and tasks in one place. It’s an essential tool for staying organised in both your work and personal life.
Now that you know what Outlook offers, let’s explore why unread emails tend to pile up and how marking them as read can make a big difference.
Why Unread Emails Pile Up and Why Marking Emails as Read Matters
Unread emails often accumulate due to several common sources:
Newsletters: Regular updates or promotional content that often don’t require immediate attention.
Spam: Unsolicited messages that clutter your inbox.
Notifications: Alerts from social media, apps, or subscriptions that add to the noise.
Marking emails as read helps maintain better email management. Here’s how:
Keeps Your Inbox Clutter-Free: By marking unnecessary emails as read, you reduce visual clutter and make it easier to focus on important messages.
Prevents Confusion: It’s easier to differentiate between new and old messages, reducing the chances of missing something urgent.
Makes Important Emails Stand Out: Once non-essential emails are marked as read, truly important unread messages become more visible and easier to prioritise.
These options ensure that managing unread emails is simple, regardless of the platform you're using.
Outlook provides multiple options for marking emails as read across various platforms. You can easily manage unread emails and keep your inbox organised, whether you're using the web version, desktop app, or mobile app.
