postie fonts

Postie publishes whatever is in the email which is why you’re seeing the email fonts.

A simple fix is to switch Postie “Preferred Text Type” to plain, but that will remove all other formatting as well.

You can create a custom plugin to remove the styling, see http://postieplugin.com/extending/

Or you can use the Clean HTML AddOn to do the same thing, see http://postieplugin.com/downloads/clean-html-addon/

Look at the html coming into Postie from your email client and see what needs to be changed.

Essentially you need to remove all the style and class attributes as well as any font elements.
