Although it is not entirely clear whether a personal website like this one is concerned by GDPR, I consider the embedXcode Newsletter and the embedXcode+ Update Direct Mail delivered through MailChimp may benefit from the new Law.
To do so, a mail was sent to all subscribers to invite them to opt-in for each newsletter. The same mail contains the usual links to edit and unsubscribe.
Please note that after May 25, 2018, the newsletters will be sent only to the subscribers who have expressly opted-in. All those who have not explicitly opted-in to receive the newsletters will be unsubscribed.
