Host for NET allows legal bulk mailing only on dedicated servers and virtual servers with KVM virtualization and only in the RU location.
Before order and setting up a server for mass mailings, you must warn us that you are going to use the server for these purposes. At the same time, based on the law on advertising, you must provide information about when and from which IP each user gave consent / confirmation to the mailing.
You must also provide an example of a letter where there will be an option to quickly unsubscribe from the mailing list. Otherwise, bulk mail traffic can be classified as spam and protection systems can automatically block port 25.
