FAQ
-
Why add a plain text version?
-
Because it decreases the chance of your legit email being marked as being spam and thus disappearing in spam folders.

Will this mess up my HTML email?
-
No, the plugin does not affect the HTML message of emails.
-
Will the people I send email to notice?
-
No, 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.
