Who has not changed their mind and thought better—or differently, at least? Who has not fancied writing something—and then taking it back immediately?

For both these purposes, strike-through formatting—a line through words, paragraphs or even but individual letters and characters—can be useful. In OS X Mail, applying such a strikeout line is easy to cross out text; you have but to know where to look for the option.

Add Strikethrough Text in OS X Mail

To strike out a word, letter or more in OS X Mail:

  • Make sure the message you are composing is using rich-text formatting.
    • Select Format | Make Rich Text from the menu if it is not.
  • Highlight the characters, words or longer sections of text you want to strike through.
  • Select Format | Show Fonts from the menu.
  • Click the strikethrough button in the Fonts window's toolbar.
  • Select Single from the drop-down menu.
  • The other choices in the menu for strikethrough style:
    • None: remove any strikethrough line.
    • Double: two lines (may not be available for all fonts).
    • Color: select a color for the line; in OS X Mail, the line is restricted to match the text's color, though.
  • Close the Fonts window.
