I've been using Jetpack's subscription feature since it first launched. However, I was just recently pointed to a problem with it. I frequently use code snippets in my blog posts (sometimes marked up with <code>, sometimes marked up with a [cci] shortcode). I use the Code Colorer plugin, which adds the [cci] shortcode for inline code snippets. But from the looks of things, the shortcodes aren't being parsed at all before Jetpack sends out emails to my subscribers.
For example, the plaintext portion ends up looking like this: https://gist.github.com/fc7a656f97cbcca1ec1d. All of the <code> blocks are cleaned up just fine, but every inline [cci] tag has been left alone. My guess is that Jetpack is skipping applying any sort of filters to the post content before building the email.
Also, I can confirm that this is happening in the HTML version of the email as well.
Does Jetpack ignore shortcodes?
The blog I need help with is eamann.com.
