Customizing the Apple Mail toolbar buttons just takes is a little clicking and dragging.
How to Customize the Mail Toolbar
Follow these steps to get the Mail toolbar how you want it. You can also rearrange items in the toolbar without having to enter the Customize Toolbar mode by holding Command while clicking and dragging the button you want to move. Drag the buttons you want to add to the location you want them. You can choose either an empty spot or a space between existing commands. You can move and delete buttons from the toolbar using this method, but you can’t add ones that aren’t already there.
Change the Mail Toolbar View
By default, the Mail Toolbar displays icons and text, but you can change to just icons or just text if you prefer by right-clicking on the toolbar and selecting an option. Your choices are Icon and Text, Icon Only, and Text Only. You can also change the view in the Customize Toolbar menu from the pull-down labelled Show.
Return the Mail Toolbar to the Default Arrangement
To return the Mail toolbar to its original arrangement, open the Customize Toolbar menu and drag the default set (near the bottom) to the toolbar. It will replace the existing setup.
