Yahoo Mail offers several ways to make text stand out when composing a message. For example, you can highlight text by adding a background color. There are even keyboard shortcuts for applying underlining, boldface, and italics.

Instructions in this article apply to the standard web version of Yahoo Mail. Yahoo Mail Basic and the Yahoo Mail mobile app offer limited formatting options.

How to Underline, Bold, or Italicize Text in Yahoo Mail

Highlight the text you wish to format, and then enter one of the following shortcuts:

  • Press Ctrl + B (Windows, Linux) or Command + B (Mac) for bold text.
  • Press Ctrl + I (Windows, Linux) or Command + I (Mac) for italics.
  • Press Ctrl + U (Windows, Linux) or Command + U (Mac) for underlined text.

Boldface and italics are preferable for emphasizing full sentences since underlining can make text harder to read. Underlining individual words (such as new terms) is more appropriate.

How to Highlight Text With a Color

To call out text by changing its background color:

  1. Highlight the text and select the Text Color button in the toolbar.

    Highlight the text and select the Text Color button in the toolbar.

  2. Select the desired color for the text itself under Text.

    Select the desired color for the text itself under Text.

  3. Select a highlight color (for the text background) under Highlight.

    Select a highlight color (for the text background) under Highlight.

Not all email programs will display your highlights or other text formatting.

You can also change fonts for emphasis in Yahoo Mail or even use ready-made email stationery.
