Either nothing fit your criteria---a remote possibility---or the e-mail just didn't make it. This is why I never use the PBS e-mail to access the digest, but a bookmark I created eons ago.
When you deleted the digest message yesterday, it went to a Trash folder in your e-mail software? Go to that folder and click on the link. It will take you to that page and show you todays digest as well as a few older days. Then bookmark that page in your browser.
