Charlie Jarvis outplayed the banking giant and made a mockery of its due diligence process. The bank decided to spam Frank's users with a campaign, probably to get them to buy some financial product that would make the bank some money. It randomly picked 400,000 users from the list Frank provided during the due diligence process and sent out mails. But the campaign went horribly wrong. Only 28% of emails were delivered and JPMC usually has a high 99% delivery rate for its campaigns. Even worse, only 1.1% of the delivered emails were opened compared to 30% for a typical JPMC campaign.
