If you’re using the Gmail website on your Windows or Mac machine, you can mark all or individual emails as read. To mark a single email as read, hover over the email from your inbox and then select the “Envelope” button.

The email will now appear faded, and your unread email count will decrease. To mark multiple emails as read, use the “Select” tool from the left edge of the emails list. Click the “Checkmark” icon for all the emails that you want to mark as read.

If you want to mark all emails shows on-screen as read, click the “Checkmark” icon from the top toolbar. All the emails on the current page will be selected. Use the “Select All Conversations” option to select all conversations in the Inbox or the category.

After making the selection, click the “Mark As Read” button from the top toolbar. This will mark all the selected emails as read.

To mark emails as unread, you can select the emails and choose the “Mark As Unread” button from the toolbar.
