Hosting.XYZ LTD has zero tolerance for sending spam. Spam includes all mailings that we have noticed, even if the sender does not consider them to be spam. Why do we have such an attitude towards spam? Everything is very simple. Everyone can suffer because of one customer who sends the mailing. Therefore, block one client who sends a large volume «useful information» easier than explaining to a million customers why their emails are not being delivered. Therefore, we reserve the right to block any newsletter without notice.
