Watch your email list twice: got burned by a tagging mix-up at a conference in Denver
Last month I was at a marketing meetup in Denver and watched a guy demo an automation tool that auto-tagged every new signup. He ran his whole list through it live on the screen after importing a CSV. I checked my own account the next morning and saw 400 contacts had tags from a quiz that ended in March. Some folks got three emails in one day because the tag made them look new. Did anyone else catch this after a live demo, or is there a safe way to test imports first?
