It’s all right, you can send mails to recipients who explicitly agreed to receive them when they joined your mailing list, in accordance with the law. However, the law requires you to allow recipients to opt out at any time, and therefore, all messages sent using Smoove allow the recipient to request the removal of their email address from the mailing list.
