Filter emails in Mail on Mac
You can use filters to show only certain email messages in a mailbox, such as those with attachments.
Turn filters on
In the Mail app on your Mac, click the Filter button at the top of the message list, or choose View > Filter > Enable Message Filter.
The Filter button turns blue to indicate the default filter (Unread) or filters you previously set are applied to the current mailbox. The filters are shown in the toolbar above the message list.
In the Mail app on your Mac, choose View > Filter.
Do one of the following:
Set a filter: Select a filter (such as Only from VIP). A checkmark appears next to the filter.
If you use more than one email account in Mail, you can filter a mailbox by account—for example, you can filter the Inbox for just your iCloud account to show unread.
Remove a filter: Select an active filter. The checkmark next to the filter is removed.
Turn filters off
In the Mail app on your Mac, click the Filter button at the top of the message list, or choose View > Filter > Disable Message Filter.
The Filter button turns gray to indicate that no filters are applied.
