Marketing companies typically maintain databases of reachable and valid email addresses, which they use to send marketing emails. Typically, a Secure Mailbox (SM) or Secure Email Gateway (SEG) for an organization accepts unsolicited emails and then handles the emails by allowing or dropping such emails based on various handling policies configured for the organization. However, such email handling typically does not curb the sender's behavior from continuing to send such emails. Provided herein are techniques through which an SM/SEG can bounce unsolicited emails sent to an organization's domain back to the sender, thereby increasing the bounce rate (percentage) of such email directed to the organization, which can cause the sender to remove the organization's email addresses from their email databases.
