Side issue but it still amuses me that companies think they can accurately measure email reads. I'm not talking about mass marketers where it doesn't matter but banks, which are required by law to switch you back to paper mail if they think your email address isn't working.
The reason you think I'm not reading my emails is that my email client doesn't autoload images, and I keep it that way because it turns off a malware infection vector, you dim bulbs.
