Please, nuke the whitespace in plaintext version of the notification emails! It’s almost hard to find the info. I highlighted the text to show how much whitespace the plaintext version of the emails contains. This obviously comes from the HTML version, which is only stripped from tags to create the plaintext version.
In quoted printable source of the message, the problem is even more obvious and the content looks even more ridiculous:
