List buyers should understand that some email delivery services do not allow you to send bulk, unsolicited email to purchased lists.  These include Constant Contact, Send in Blue, Hubspot, Mail Chimp, Brevo, SendGrid, Aweber, Vertical Response and others. Also note that Gmail is not an appropriate system for sending large numbers of email messages.
