Adds addresses to your unsubscribe list, or your workspace's list if you belong to one. Sequences then stop sending to them. Addresses are stored in lowercase.

Send email (and optionally name) to add one address, or emails to add several. Adding one address that is already on the list changes nothing. With emails, an address already on the list has its record replaced, which resets createdAt and drops its name, messageId and sequenceId.

If any address in emails is not valid, nothing is added.
