Criminals used 79 dormant domains to impersonate a major realty team.

Unauthorized or unexpected email traffic — whether from compromised accounts, misconfigured integrations, scraping bots, or aggressive third‑party services — poses a material reputational risk for brokerages and their sending domains. Email providers use engagement signals and complaint rates to score domain and IP reputations; anomalous volumes, high bounce or complaint rates, and spam trap hits quickly degrade those scores. For mortgage firms that rely on timely client communications and application workflows, reputational damage translates into missed messages, harder inbox placement, and increased operational friction as deliverability drops and remediation efforts distract compliance and marketing teams.

Mitigating the risk requires a layered program that combines security, email authentication, and governance. Firms should enforce SPF/DKIM/DMARC, transactional versus promotional separation, strict access controls, and vendor contract clauses that limit outbound volume and require logging. Continuous monitoring for anomalies, rapid incident response to isolate compromised accounts, and direct liaison with mailbox providers help restore standing when issues arise. Maintaining clean lists, clear unsubscribe handling, and routine audits of email integrations protects brand trust and preserves critical customer communications.

Key elements:
– Unauthorized traffic sources: Compromised mailboxes, misconfigured APIs, third‑party platforms and bots that generate unapproved sends.
– Reputation impact: Email providers downgrade domains/IPs based on engagement and complaint metrics, reducing inbox placement.
– Business consequences: Missed client communications, increased operational remediation, brand trust erosion and potential regulatory scrutiny.
– Preventive controls: Authentication (SPF/DKIM/DMARC), rate limiting, access governance, segmentation of message types and vendor vetting.
– Detection and response: Continuous monitoring, alerting for anomalies, rapid account isolation, and direct engagement with mailbox providers to remediate issues.
