The heart and soul of email is writing messages, so it is not surprising that you would have some kind of editor built into an email program. Generally, email programs include text editors that are simpler than most word processors. this is really not much of a problem, because email sends essentially ASCII text, which is what text editors are best at. There are email programs with a spell - checker built into the program. This is an especially handy feature, because it is very embarrassing to send an email to someone with misspellings in it. Many email programs also give you the option to use some other text editor you really like and import the document into the email program for mailing.
