Email notifications stopped working

I've been on astromart for years and select the preference to receive email notifications as ads are posted. I've always received them. Except for the last several months, I don't receive any email notifications. I go and check the boxes of the kinds of ads I'd like to receive, but I get nothing. I've even tried unchecking it, logging off and on again, and rechecking what I'd like to receive. Nothing works. They're not in my spam folder. No where. I'd really like to be notified via email as I used to be. Thanks for any help!
