No longer getting horoscopes in my inbox - was getting them for several months and they stopped - any insight?

Had signed up for the Yahoo Horoscopes and was getting them for several months. About 3 weeks ago this stopped. I have gone in and reset the alert, it shows all the correct info, yet I do not get them into my non-yahoo account where they were previously delivered. They are not in my spam folder either - they must be getting deleted prior to reaching my inbox. Any one know any ideas of how to fix this? Or what email address they come from so I can attempt to add that as an approved sender? I've tried with the info I have and it doesn't work.... Thanks so much for any help!
