For several months now I am not receiving email notifications for snipes fired. The box in "my configurations" notification is checked, I have tried to unchecked and check it again a couple of times in the past, I have monitored my spam folder and also tried changing my email address to my secondary email address but I still don't receive mails.

Please advice, thanks!

You did not provide any relevant information about your account so I can't check.
I would guess you did not verify your email address. The simplest way is through the password reset at https://www.myibidder.com/login/reset

That did it, thanks.
