I use gmail and don't have any issues. I do get things regularly into the spam folder so have have got into the habit of looking in it every day. Messages in there are deleted after 30 days so you need to keep an eye on it.
Maybe add this email to your contacts firstname.lastname@example.org
and see if that helps.
If you hadn't got any I would suspect you had a tiny error in the email address you used to subscribe [like an extra dot or space].
Do you actually read your emails on gmail or use something like outlook express to get them on your computer ?
