Owned by CareerBuilder, LLC; same owner of workinretail.com. See:
By providing an email address to workinretail.com, you will receive no automated notification of opt-in to email from jobs.net routed through sendgrid.net
Email header at least sometimes originates from a Careerbuilder LLC IP address, example 208.82.x.x or 208.88.x.x.x See: http://bgp.he.net/AS20223#_prefixes (Careerbuilder LLC owned IP network ranges)

I found no notification on the workinretail.com website, that an email would come come from "jobs.net" or be routed through "sendgrid.net". Spam by obscurity.
If jobsnet / Careerbuilder LLC wants a green rating from me, have a new policy requirement for senders like workinretail.com to post a notification that "jobs.net" will be used.
