How can I prevent brand and sender profile impersonation in emails and what actions can I take?

Email marketer from ZeroBounce explains that setting up email authentication protocols like SPF, DKIM, and DMARC is crucial for preventing email spoofing and phishing. These protocols verify that emails are sent from authorized servers and domains, protecting your brand's reputation and improving email deliverability.

Email marketer from Proofpoint responds that domain monitoring can help detect and address fraudulent use of your brand. This includes identifying lookalike domains used for phishing attacks, and monitoring for unauthorized use of your logos and trademarks in phishing emails.

Marketer from Email Geeks suggests providing plain English instructions on how to find email headers and potentially contacting the sending platform to cut off the impersonators.

Email marketer from Red Sift explains that subscribing to a threat intelligence feed can help identify and block malicious IP addresses and domains associated with phishing and spoofing campaigns. These feeds provide up-to-date information about emerging threats, allowing you to proactively protect your email infrastructure.

Email marketer from Reddit suggests educating your users about phishing and spoofing tactics. Train them to recognize suspicious emails, verify sender identities, and avoid clicking on unfamiliar links or attachments. Encourage them to report suspicious emails to your security team.

Email marketer from Vade Secure shares that using AI-powered anti-phishing solutions can help detect and block sophisticated phishing attacks that impersonate your brand. These solutions use machine learning to analyze email content, sender behavior, and other factors to identify and block phishing attempts.

Email marketer from Email Marketing Forum responds to report any instances of brand impersonation to anti-phishing organizations, such as the Anti-Phishing Working Group (APWG). These organizations can help track and shut down phishing sites and malicious email campaigns.

Email marketer from Mailjet shares that implementing BIMI (Brand Indicators for Message Identification) can help improve brand recognition in email inboxes. BIMI enables email senders to display their brand logo alongside authenticated email messages, providing a visual cue that the email is legitimate. BIMI requires DMARC authentication.

Email marketer from EasyDMARC shares that monitoring DMARC reports provides insights into email authentication failures and potential spoofing attempts. By analyzing these reports, you can identify unauthorized senders and adjust your DMARC policy to better protect your domain.

Marketer from Email Geeks suggests involving legal counsel to address copyright and trademark infringement, as well as CAN-SPAM violations. They emphasize the importance of support teams obtaining full email headers to investigate the source of the emails and potentially take action against the sending platform.

Expert from Email Geeks explains that the Reply To header is not a protected header and nothing can protect from spoofing it.

Expert from Email Geeks advises to be prepared to spend significant resources to identify the perpetrators, noting that it can be expensive and may lead to dead ends due to botnets.

Expert from Word to the Wise responds that a path to pursue when dealing with trademark/brand abuse is to send a cease and desist letter. The page mentions the importance of taking action against abuse even if it seems too small to worry about.

Expert from Spam Resource responds to actively monitor your sender reputation and block lists for any signs of compromise. If you detect suspicious activity, investigate immediately and secure any compromised accounts to prevent further abuse.

Documentation from Google explains that implementing DMARC (Domain-based Message Authentication, Reporting & Conformance) helps prevent email spoofing by allowing domain owners to specify how email receivers should handle messages that fail authentication checks (SPF and DKIM). DMARC policies can instruct receivers to reject, quarantine, or deliver emails, and provides reporting mechanisms to domain owners about authentication results.

Documentation from dkim.org explains that DKIM (DomainKeys Identified Mail) is an email authentication system designed to verify the domain name of an email sender and the integrity of the message. It uses cryptographic signatures to allow the recipient to verify that the message was indeed sent by the domain it claims to be from and that the message content hasn't been altered in transit.

Documentation from Agari explains that you can analyze the email headers of suspicious emails to identify the source and determine if it is legitimate. The headers contain information about the sender's server, routing information, and authentication results. This can help determine if the email is spoofed or not.

Documentation from Microsoft shares that SPF (Sender Policy Framework) records are a type of DNS record that identifies which mail servers are permitted to send email on behalf of your domain. Creating and maintaining accurate SPF records helps prevent spammers from forging the 'From' address on your messages to make it appear as though they're coming from your domain.

Documentation from NIST responds that they publish guidelines and recommendations for securing email systems, including best practices for email authentication, encryption, and access control. Implementing these recommendations can help strengthen your email security posture and reduce the risk of brand impersonation.
