Unsubscribe, Opt-in, and Preference Center
How unsubscribing, subscription confirmation, and the preference management page work.
Respecting subscriber choices is both a legal requirement and key to better deliverability.
Unsubscribe Link
Every marketing email automatically includes an unsubscribe link (/email/unsubscribe). An unsubscribed contact will no longer receive campaigns — the exclusion is automatic, and it's not possible to accidentally re-subscribe them.
Subscription Confirmation
With double opt-in, a new subscriber receives a confirmation email (/confirm-email) — only after clicking this link will they be added to the database as active.
Preference Center
The /preferences page allows subscribers to manage their newsletter topics instead of fully unsubscribing: for example, to keep "promotions" but disable "news."
