"Unsolicited Email" means an unwanted email message that forces the recipient to assume the cost of receiving, storing, and removing it from one's email box. There is also another term - "Bulk Email". The difference between legitimate "Bulk Email" and "Unsolicited Email" is very clear. The legitimate Bulk Email requires the sender to have verifiable permission from the recipients before starting to send messages to their email boxes, something totally opposite the Unsolicited Email.
According to the definition of Spam provided by The Spamhaus Project, "A message is Spam only if it is both Unsolicited and Bulk. Unsolicited Email is normal email." Spamhaus also suggest that "Bulk means that the message is sent as part of a larger collection of messages, all having substantively identical content.
HostColor often receives inquiries for VPS or Dedicated Server Hosting that prospective clients want to use for sending Unsolicited and Bulk email messages. Such usually come with a request to use 32, 64, or 128 IPv4 addresses or even a whole /24 IP subnet. Please be advised that this is unjustified use of IP resources, which is against ARIN guidelines. For this reason, we do not accept such service orders.
If you need a Cloud Server, a VPS Hosting delivered from a stand-alone physical server, or a bare-metal Dedicated Server, hosted on a network that does not tolerate Spam, HostColor.com is the right place to be.
