Tools

• click2mail_cancel_job ~215 tokens
  WRITE: cancel a SUBMITTED job. The vendor documents this only for jobs paid by invoice and only before processing for mailing has started; otherwise it fails. The mailing is stopped for good, so get the user's explicit go-ahead first; `confirm` must be true. To remove a draft use click2mail_delete_j
• click2mail_check_addresses ~222 tokens
  Validate and standardize up to 100 US postal addresses (USPS/CASS correction) before mailing. Read-only: nothing is saved or sent. POST /molpro/addressCorrection.
• click2mail_create_address_list ~401 tokens
  WRITE: upload a recipient address list (up to 500 addresses) to the account. The list is standardized (CASS) by Click2Mail; poll click2mail_get_address_list until status 3, then use its id in click2mail_create_job. Creates data only; nothing is mailed or charged. POST /molpro/addressLists.
• click2mail_create_job ~715 tokens
