The list we uploaded from our previous email marketing provider into Marketo was contaminated. The list has many individuals that shouldn't be unsubscribes - unsubscribed. So, we don't have an accurate list any longer. We don't want to subject ourselves to being reported as SPAM, but know we are missing a huge portion of our original list. We are changing our name beginning October 1. Can we send out an email to all our members (with email) notifying them of the name change and requesting how they want to stay connected to us? This way, we may be able to retrieve those that didn't want to be unsubscribed? Do we open ourselves up to being black listed? HELP.
