Getting an email marked as important can sometimes feel urgent or overwhelming, especially if you’re unsure how to prioritize it. In this 2025 guide, we’ll break down what an important email really means, how email services determine importance, and what actions you should take to handle them efficiently on Windows, Mac, and mobile devices.

Why Are Emails Marked as Important?

Sender’s Priority Setting

Some email senders manually mark messages as important when they want to grab your attention or indicate urgency.

Email Service’s Automated Tagging

Email providers like Gmail, Outlook, and Yahoo use algorithms that automatically tag messages as important based on:

  • The frequency of communication with the sender

  • Keywords like “urgent,” “action needed,” or “important”

  • Your past behavior (opening, replying, flagging)

Company or Organizational Policies

In professional environments, internal communication systems may auto-tag emails that require employee action within a deadline.

Understanding why an email is marked important helps you decide how to respond.

How Email Services Identify Important Emails

How Email Services Identify Important Emails

Gmail

Gmail uses AI and machine learning models to determine if an email is important by analyzing patterns like:

  • Who you email most frequently

  • Which emails you open and respond to

  • Keywords in the subject line and body

Important emails are flagged with a yellow arrow next to them.

Outlook

Outlook uses “Focused Inbox” and can also allow senders to manually mark emails as High Importance. These emails are labeled with a red exclamation mark.

Yahoo and Other Providers

Other platforms like Yahoo may not automatically mark importance but allow users to star or flag emails manually for attention.

Knowing your platform’s method helps in managing your inbox better.

What to Do When You Receive an Email Marked Important

Read the Subject Line Carefully

Important emails usually carry descriptive subject lines like “Action Required,” “Response Needed,” or “Update Request.” Read carefully to anticipate the urgency.

Check the Sender’s Address

Verify if the email is from a trusted source. Important tags can sometimes be abused in spam or phishing attempts.

Open the Email Promptly

Even if you can’t act immediately, opening the email ensures you understand its nature and any deadlines involved.

Assess the Urgency and Take Notes

Identify if the email:

  • Needs immediate action

  • Requires a reply

  • Is simply informational

Make quick notes if needed.

Prioritize and Schedule Actions

If it’s not something you can handle immediately, set a reminder or create a task in your to-do list app.

How to Manage Important Emails Efficiently

Use Flags, Labels, or Stars

Most email clients allow you to flag or start emails for easy access later.

Example:

  • Gmail: Labels

  • Outlook: Flags

  • Apple Mail: VIP list

Set Up Email Filters

Create rules that automatically move important emails to a priority folder.

Enable Notifications for Important Emails Only

Customize notifications to alert you only for emails marked as important to avoid distraction from less critical emails.

What if You Keep Getting Unnecessary Important Emails?

Adjust Importance Marking

In Gmail:

  • Deselect “Mark as Important” manually for future emails from that sender.

In Outlook:

  • Move emails to “Other” manually to train the system.

You can fine-tune your email system to mark only truly important messages.
