Use of Generic, Non-Corporate Email Domain (medium) The entity, GNS Group, which claims to be a Social Media Marketing Agency, uses a generic, free email domain (@GNSGroup@mail.com) for its primary contact information, rather than a dedicated corporate domain. This suggests a lack of professional infrastructure or formal business registration.. Minimal Social Media Presence for a Marketing Agency (medium) The GNS Group Twitter account (@hellalosses), which purports to be a Social Media Marketing Agency, shows a very limited network, listing only '30 Following' as of the search date. For an agency specializing in social media, this lack of a robust, self-marketed presence raises questions about its operational scale and effectiveness.
