This is a plugin you need but probably don’t realise. It does one thing very well and very simply. For every HTML email sent by WordPress it will provide a text alternative (within the one email).
99% of all email clients will just show the HTML version of the email. The other 1% can’t properly display HTML and will show the plain text email. Without this plugin, they would have had nothing to show. The other major benefit of this plugin come from the fact that will reduce the chances of the emails you send ending up in the recipients spam folder.
