I will soon be working with someone that wants to set up a Zap using Constant Contact. They have a few mailing lists that need contacts to be added or removed depending on the flow of data.
My ‘how to’ question is, can we remove and add contacts from lists using the provided action “Update Contact”? According to the integration page empty values will be cleared so that could also apply to lists. https://zapier.com/apps/constant-contact/integration
