What Does It Mean to Flag an Email?
To flag an email means marking an email message as important so you can easily find it later or remember to take action. Email services like Gmail, Outlook, and Yahoo allow users to flag or star emails to keep track of important messages such as work tasks, invoices, or reminders.
Flagging emails helps you stay organized and makes sure you do not forget important information.
Why People Flag Emails

Many people receive dozens of emails every day. Because of this, it becomes difficult to remember which emails need attention. Flagging helps highlight messages that require follow-up or action.
People usually flag emails when they:
- Need to reply later
- Want to save important information
- Have tasks to complete
- Need reminders
- Want quick access to messages
Flagging emails works like a digital reminder system inside your inbox.
How Email Flagging Works
When you flag an email, the email system marks it with a special symbol such as:
- A flag icon
- A star icon
- A colored label
- A reminder sign
This makes the email stand out from other messages.
After flagging, you can easily find these emails in a special folder or section called Flagged or Starred.
