Email notifications have stopped arriving

Hello there -- I hope you can help?

My Username is: alanlb0306.

My email notifications stopped arriving at 10:28am this morning, although I have made no changes to my account...whilst notifications are still appearing in my account on your website.

Can you help with this, as I would like email notifications to continue/re-start as soon as possible.

Hope you can help with this.

Just so you know. I am continuing to receive emails from other sources at my registered email address without interruption.

Thanks, AlanLB.
