オプトアウトしたユーザーを、再度復活させる方法について考えております。
ユーザーの同意があった上で、
Marketo側でどういうフローや手続きをしてもらえれば、再度復活できるのでしょうか。
その手順について確認したく思っております。何卒よろしくお願いいたします。
Well, that is always a tricky one and depends on local regulations and your company's policies mostly.
Technically, you can use any legitimate means of communication to provide the user with a link to a webpage where they can opt-in again. Your backend processes should always be set up to process an opt in and set all the relevant consent values to the correct one based on this new value coming in. Of course ideally you would have a preference center page set up already for the user to give you all the details what they do and do not want to receive. You could use that link to present to the user and leverage existing processes.
