Normally, it's just delayed. We've made every effort possible to ensure our emails get through spam filters, and we've confirmed that 90% get through. The remainder usually fall into these categories: - "held up" by other computers in the chain of delivery. - Ended up in your Junk Email folder of your email system. - You're using a service such as Spam Arrest, which requires manual acknowledgement by us. If it's been over an hour, and it's still not arrived, send an email to us via the Contact page and a real live human will sort it out for you.
