Breaking change: we've made DELETE /subscribers/{id_or_email}
actually delete subscribers instead of just unsubscribing them.
This change was implemented to align the API behavior with common REST conventions, where DELETE operations typically remove resources entirely. The difference between deleting and unsubscribing a subscriber is significant:
You can still unsubscribe users by calling PATCH /subscribers/{id_or_email}
and setting the type
field to unsubscribed
. This method is preferable if you want to retain subscriber data while respecting their wish not to receive emails.
