If you signed up for the newsletter, but didn't get it, drop me a line to let me know, and we'll see what happened.
My first guess, though, is that you'll need to check your spam filters to see if mail from "email@example.com" has been flagged as spam. 'Cause it's not. It's totally not! :)
The question you have to ask first is 150 returned from just how many sent? People do change their email addresses, accounts are closed or cancelled. People enter the wrong email address through typos (you gotta love the days when fingers and keyboards don't want to communicate), or signed up with an account they have forgotten about. A lot of things could have happened - and yes, including a glitch on the mail server.
But I'm guessing that with all this awesomeness, while 150 bounces is a significant number, it's not necessarily a high enough percentage to indicate some form of system stuff-up.

I got the letter stating that you were going to send the letter, but that was all. Your email is in my addy book or I would not have gotten the first notice.
