First, check if the message got stuck in your SPAM or Trash folder. If there's nothing in either of these folders, perhaps you haven't waited long enough. It's not unusual for the notifications from SSS to take anywhere between 30 minutes to an hour before arriving in your inbox. If you still haven't received the message after waiting that long, ensure that your network administrator isn't blocking messages from sss.gov.ph, especially if you're using an email that is not yahoo.com, gmail.com, or hotmail.com. Suppose all the suggestions mentioned above don't work. In that case, you should request technical assistance by emailing onlineserviceassistance@sss.gov.ph (Don't forget to include details of your problem, your details such as complete name and SSS number and attached copies of your UMID or two valid IDs).
