block_address

What it does

Add email addresses or whole company domains to the organization's Do not email list. Campaigns never email them, lead searches skip them, and any active enrollment they match is paused. Cold email only: product email (journeys) still reaches them, and other organizations are not affected. Pass `entries` for many at once, such as a customer list (up to 5000 a call; reason 'existing customer'); app users are skipped by campaigns already and need no block. Also for 'stop emailing us' replies not from the contact themselves (a colleague, an admin). For the contact's own request use unsubscribe_contact.
