There are several email clients available in Emacspeak. The Gnus utility can actually be used for both email and news. Press Meta+X to start Gnus, then press M to use the mail client.

The easiest tool to use is RMAIL. To send a message using RMAIL, press Ctrl+X, then type rmail. When you are in RMAIL, press M. Fill in the To: and Subject: fields. Put the body of the message below the line that reads -text follows this line-. To send the message when you are finished, press Ctrl+C twice in succession.

To read a message using RMAIL, press Meta+X, then type rmail and press Enter.
