To play it safe, I would not include the password in an email. Just call the person and tell them the password. Alternatively, you could make the password a fact known only to the two parties and give a hint what the password may be in the email. Obviously, that's less secure. If email is really the only choice and you cannot think of hint-able shared secret, you should send the password in an email separate from the email with the compressed file.
