Since release Whymper V1, SAM (SecuTix Audience Management) filters out automatically all contacts that refuse explicitly marketing communications (except if the campaign contains only "operational" (and non-marketing) information directly related to contractual obligations towards the customers, for instance informing them about major changes affecting an event for which they ave have purchased tickets). In this case, you must select the campaign type called "Information directly related to a contact's purchase or reservation".

In order to be fully compliant with GDPR regulations, release Whymper V3 of SAM will filter out automatically all contacts that did not give their explicit consent. As a result, as of mid-November 2018, contacts who have not provided any consent information (neither positive, nor negative) will not receive your marketing campaigns anymore.
