What's the size when you look at it in the newlords directory itself, the file itself before you send it? If it's over 1K (that's what Windoze shows it as - they're really 200-400 bytes) there's probably something wrong with it, verifiable by starting a new game with that nation.

Try to make sure your email program (which is what, by the way? So people can give better advice.) is getting it as an attachment, and using Mime encoding and not, mmm, UUEncode or somesuch (Mac's and a few other machines used a variant encoding for mail / Usenet that couldn't easily be handled on Intel machines). And as someone pointed out, if you make a zip file containing the pretender and mail the zip file, that might work better.
