There's already a package for this; html2text. 

I've enhanced it for use at work, where I read Outlook generated email
with Emacs:

(require 'html2text)
(add-to-list 'html2text-replace-list (cons "&#146;" "'"))
(add-to-list 'html2text-replace-list (cons "&#39;" "'"))
(add-to-list 'html2text-replace-list (cons "&#8211;" "-"))
(add-to-list 'html2text-replace-list (cons "&#8216;" "'"))
(add-to-list 'html2text-replace-list (cons "&#8217;" "'"))
(add-to-list 'html2text-replace-list (cons "&#8220;" "'"))
(add-to-list 'html2text-replace-list (cons "&#8221;" "'"))
(add-to-list 'html2text-replace-list (cons "&#39;" "'"))
(add-to-list 'html2text-replace-list (cons "&#8230;" "..."))
(add-to-list 'html2text-replace-list (cons "&#8211;" "-"))

(add-to-list 'html2text-remove-tag-list "sup")

(setq html2text-remove-tag-list (delete "br" html2text-remove-tag-list))
(add-to-list 'html2text-remove-tag-list "style")
(add-to-list 'html2text-remove-tag-list "span")

(defun html2text-clean-newline (p1 p2 p3 p4)
  (html2text-delete-tags p1 p2 p3 p4)
  (newline))

(add-to-list 'html2text-format-tag-list
	     (cons "o:p" 'html2text-clean-newline))

(add-to-list 'html2text-format-tag-list
	     (cons "br" 'html2text-clean-newline))

(defun html2text-delete-comment ()
  (interactive)
  (let ((buffer-read-only))
    (goto-char (point-min))
    (while (re-search-forward "<!" (point-max) t)
      (delete-region (match-beginning 0)
		     (re-search-forward ">" (point-max) t)))))

(defun html2text-delete-xml ()
  (interactive)
  (let ((buffer-read-only))
    (goto-char (point-min))
    (while (re-search-forward "<xml>" (point-max) t)
      (delete-region (match-beginning 0)
		     (re-search-forward "</xml>" (point-max) t)))))

(defun html-clean ()
  (interactive)
  (html2text)
  (html2text-delete-comment)
  (html2text-delete-xml))


In a buffer with html: M-x html-clean

Do that before replying.
