I guess it depends on what OP meant by “immediately”. If they meant the same day, maybe. If they meant within seconds or a few minutes, which is what I interpreted it as, then probably not. It takes time to transfer data out of a secure network, unless they gave the company direct access to a feed from the website, which would be really risky for a bank to give any organization a direct, real-time feed of any kind that is on the same network as financial data. I mean unless the bank also owned the spamming company, but that seems risky for reputation.
