Cornerstone UK's email sending IPs have been temporarily blacklisted by Mailspike, a community-oriented IP reputation authority, due to a high number of email delivery failures originating from certain customer accounts. During this time, emails may fail to deliver. This is our top priority, and we are working closely with the vendor to resolve the problem as soon as possible.
