Mac OS X Mail: Plain Text Compared to Rich Text (RTF)

Mail can send text or rich text format messages, but not all recipients can read rich text (RTF).
Symptom

Some of your email recipients cannot read the messages you send, or do not see text formatting the way you do.

Solution

You can compose email in either plain text (.txt) or rich text format (RTF).

Plain text (.txt)

Rich text format (.rtf)

Choosing a format

Mail defaults to rich text so that you can take advantage of its formatting choices. You may change the default behavior by using these steps:

To automatically reply to messages in the format used by a sender, check "Use the same format as original message" in the Composing pane of Mail Preferences.

Changing format on the fly

If you want to send a message that is not in your preferred format, you may do so without changing the preferences back and forth. After you click Compose for a new message, choose the alternate format from the Format menu.
