The mailing list will only be used for infrequent announcements, such as when a camera reaches a new stage of development. It is usually one email every few months. We won't send daily SPAM like many organizations.
If you would like frequent updates on when we post new sample photos and such, you can follow us on Twitter, Facebook and Flickr.
We use MailChimp to manage our mailing list, so after you subscribe you'll get a confirmation email from them. (Some people report not receiving the mailing list after they have subscribed. Your email provider may be blocking MailChimp. Again, we only send an email every few months.)
