Email services resumed. We are now sending via an email service rather than our own email servers.
More technical info
We are a new site sending out 1,000s of emails a day. Because we are so new our emails get caught in spam databases such as Spamhaus.org
Periodically we will pause all emails while we wait for our mail server IPs to be removed from the list. This can cause the email backlog to be in excess of 1,000 emails.
