Outgoing mails blocked.

Can you review why d.obradovic@viangostudios.com is blocked? Your support is stating that problem is SPAM. But we are working as sourcing company and we are BUYING, not selling, so people are happy to get our emails, I don't believe any of them consider our emails as SPAM. If you still consider this being breach of your terms can you please unblock the email since it is first error from our side and we will use zoho campaigns as you suggested when sending multiple requests for quotation.
