I have newsletter sending in HTML. However, is there a way for newsletter to send both HTML and Text so that receivers email can import the one according to their settings? Example, outlook has a way to receive email as html or plain text, and most newsletter providers offer a way to add your text version at the same time and it sends both and simply displays based on the user's settings. This is also proven to avoid your newsletter as being filtered as spam as most spammers do not send in both formats or in plain text.

Is there a module or a workaround to have my newsletters send an html version AND a plain text version controlled by me? I really dont like the system auto creating a plain text version on the fly since I have no control over how it displays and marketing 101 of plain text campaigns shows how important it is for us to have that full control of adding the plain text ourselves, much like those 3rd party providers do.

Any ideas on how to achieve this for simplenews?

Thanx.
