The unfortunate truth is that a lot of valid email gets labeled as spam and will never get to you. To ensure that you do receive the confirmation email, make sure that you have done the following:
1. Check your spam or bulk folders for my email
2. Make sure you have added the following email address to your Address Book, Whitelist, or Approved Senders list: chris@chriscade.com
3. After you have done that, you might also try re-subscribing either with the same email address or a different one.
4. If none of the above work, then contact me or your Internet provider to see if they have blocked the message.
Also note: Sometimes it can take a few hours to receive your email - especially if you are using Yahoo. You may have also accidentally entered your email address incorrectly - I know, because I do this sometimes too! :)
