Fix HTML/Plain text email issue that displays message:
"This is a HTML email and your email client software does not support HTML email!"

For Opencart 2.0.x-2.3.x

WHY I wrote this module:
- I received this message on one of my email programs, and didn't want my customers to see it
- Previewing the email on my mobile device also showed this message

What this module does:
Forces a text segment on all html emails without any html tags. It supports newline characters where a <p> was used.It is fully compilable with other newsletter modules I have written. The customer will never see: "This is a HTML email and your email client software does not support HTML email!" again

Installation:

This module uses vQmod - Drop the XML file into your vQmod folder. Don't forget to backup first.

Compatibility:
This file does not modify language files, so it is multi-language compatible. This file does not

modify templates, so it is multi-template compatible

Use:
Just send emails, newsletters, etc as you always have. The customer will get a cleaner email, which is also less likely to go to spam email.

Uninstall:
Just remove the file.
