Don't think I'm a member in any of them - but I know from some I am with, that alot of companies have updated their sites, and now only send to categories you select. One or two I only found out by logging in and finding the categories there - others have been alot more generous and told members they have introduced categories.
It may be worth your while logging in to edit your information in them to see if any have introduced categories. They may not have done - they may just not be sending mails, but it's worth checking out
