Is it Live/Outlook/Hotmail ?? - If so this is not down to CL its down to the email provider, for some reason they 'auto block' many gambling related emails.
Wife in same boat as you, offers, mails galore then all of a sudden nowt.
Worth a check tho as even tho no emails, spins are quite often in your account so worthy of keeping a regular check on this thread. Would be very surprised if they had totally bonus banned you as I've not read any posts/threads over the past couple of years of players getting BB'ed by this particularly casino group, they exclude their slots themselves to avoid this situation very well IMO.
I changed my CL registered email to my yahoo account and since have had no problems
