So I'm being asked to send a bulk email to a list of people who have NOT specifically subscribed to receive email from my company. However, these addresses are people within a number of larger organizations (school districts, for example) which have given us permission to mail their members. Is this allowed? I'm not so sure it meets the requirements for "express and verifiable permission" (as per Mailchimp TOS, our ESP in this case). But maybe it does since these organizations "own" these inboxes. Any insight here would be great!
