Play any email aloud with a narrator's voice by right-clicking selected text or clicking the speaker icon next to a message.
Choose between a male or female narrator and fine-tune the volume from an easy pop-up menu.
Reading buttons are placed next to archive controls in the header and inbox list, so you can listen without leaving your workflow.
