Spam-advertised business. 'Special offers' sent unsolicited to emails on a purchased bulkmail list.
UPDATE [2016-05-31]: Messages advertising oypla.com were sent in a 9-month period between September 2013 and June 2014. No new messages have been seen since June 2014. According to the company owner, the unsolicited email campaign was the work of a developer who is no longer with the company.
I have therefore updated my comment to remove the 'Spam' flag and 'Do Not Trust' rating.
