The Twittermail settings at the Cut-off option state that: "If you leave this blank we'll cut of the email you send after two breaks.". Possibly this is what happening (a break, a blank line and another break makes two breaks).
To remedy this you can set a Cut-off option, so that it only breaks after that bit of text.
