Can I email my non-confirmed or purchased opt-in list and ask for confirmation through M5 Subscriber?
Purchased? NO, you cannot use M5 Subscriber to clear up confirmation of an existing email list if it contains recipient email addresses that you did not directly obtain through your own business operations. Non-confirmed? You can upload your existing customer or subscriber list to M5 Subscriber, however, as long as it does not contain purchased email addresses and as long as your list contains addresses of people who may expect to receive email from you. You must have a prior business relationship with all recipients of email containing our Mach5 trademark (including in our URL).
