In different companies, including our own company network, we created fake employee profiles and accounts. From these mail accounts, we programmed the sending of several emails to the wrong recipients. All those who responded, immediately received an “auto-reply email” with our message.

The response rate to the emails telling us about our mistake was over 80%. Moreover, in most cases the response arrived after no more than 15 minutes. The response rate of the second email, revealing the message from “Cooperación Internacional”, achieved 9%, which multiplied by five the visits to the charity’s website, compared to ordinary days.
