Domain

New domains are cheap. You don't spam from mybiz.com. You spam from mybizmail.com, mybizmarketing.com, mybizoffers.com, etc.

For instance:

  • Facebook notifications come from facebookmail.com,
  • CarMax spams from email-carmax.com.
  • AT&T uses att-mail.com.
  • And so on.

They don't all do it, but many do.

And if they burn their main domain, it's an easy option.
