Notifications not Working Correctly for me

Hi there I am having a problem with receiving notifications, I am not receiving notifications like I use to this has happened since I recently changed my email from a college email to a personal one. The notifications I use to receive were weekly suggested accounts that I could follow and weekly sketchfab offers or new information. I received one notification to my old email even though I have changed it and from then I have received nothing.

If you could help in anyway it would be much appreciated

I have contacted you in a private message for further details.
