Can I use Zumbox to send highly sensitive information?
Yes. Zumbox is compliant with the security standards of the financial, healthcare, and banking industries. Zumbox allows mail senders who are sending highly-sensitive information to implement their own “security keys” for each piece of mail. In this case, the mail recipient would be prompted to enter some private information that you specify in order to open their mail (for example, a customer account number).
