Good day all,
I’m working with a very credible, but not well known ESP. They will be supplying email lists that have been through a permission pass - meaning they are opt-in and CAN SPAM compliant. They quietly supply various services to many of the Fortune 500, so they would not compromise their and their client’s reputation by spamming or selling lists that are not 100% opt-in.
This page suggests that Klaviyo does not allow third party lists. Can anyone shed some light on this? There must be a some exceptions.
Thanks in advance…..Jim
