We recommend using the following subscribe and unsubscribe procedures as they offer increased protection against the misuse of data.
- Confirmed opt-in or double opt-in subscription
- Single opt-out or confirmed opt-out unsubscription
We do notrecommend using the double opt-out unsubscribe procedure, since this method has many intermediate steps and therefore makes unsubscription more difficult.
It is important that you always let your recipients know what the next step involves (for example, on landing pages or in confirmation mailings).
Try not to make your subscription and unsubscription processes too complicated, otherwise you may lose prospective subscribers.
