# Lightning Guide: How to prevent email spoofing from ruining your brand 11 minutes August 19, 2025 Email spoofing is one of the most prevalent tactics malicious individuals employ as part of their social engineering and phishing attacks. There’s a good chance that you’ve already been a target of it at least on one occasion. The main reason for this is that email spoofing can trick anyone from a single person to a large enterprise. What’s even scarier is that scammers send billions of fake emails each day with the intention of spoofing users. Given that the majority of cyberattacks begin from accepting an email message, it’s best to learn what a spoofed email is all about and how you can prevent falling for it. ## **What Is Email Spoofing?** Email spoofing is one of the most common and oldest cybercrimes that can trace its origins as far back as the year 1996. It is an approach where malicious individuals send seemingly harmless messages to trick their would-be victims. One of the main activities of a spoofing practitioner is to change their email metadata, such as the email address or display name they use to appear as a trusted sender. They may even resort to techniques that can easily fool users into thinking a sender is legitimate by changing letters in a business name, such as using “PayRal” rather than “PayPal” or “Facepook” instead of “Facebook.” Oftentimes, cybercriminals use social engineering as part of their spoofing strategy. They do this by impersonating a reputable sender – be it as a business partner, co-worker, or stakeholder. Malicious individuals employ such tactics to take advantage of their target’s emotions when receiving an email from someone they think they know. One prevalent technique they use is creating a sense of urgency. They make victims think something bad will happen if they don’t click the email as soon as possible. This doesn’t give them enough time to think the situation through and realize it’s a scam. ## **How Does Email Spoofing Work?** People who perform email spoofing carry out their tactics by using a Simple Mail Transfer Protocol ( [SMTP](https://sendgrid.com/blog/what-is-an-smtp-server/)) server and a regular email platform like Gmail, Yahoo, or Outlook. After composing the content of their message, these malicious individuals copy the fields located in the message header. These fields are often the from, return path, and reply to sender addresses. The goal here is to deceive the recipient into believing that the email comes from the sender address forged by the scammer. Email spoofing is possible because the SMTP standard doesn’t come with a way to confirm if an address is genuine or not. Fortunately, there are methods and protocols available for users to combat email spoofing. ## **Types of Email Spoofing** Scammers employ a few methods of email spoofing that come with varying complexity. The various types of email spoofing also differ with regards to the part of the message an attacker forges for their attack. Here are the three most common variations used today: ### **Email Domain Spoofing** Cybercriminals will also attempt to trick users into believing that an email comes from a legitimate website or domain. In such attempts, these attackers often resort to using the address of a trusted entity by changing the “From” header while changing the email address and display name to show deceptive details. ### **Email Domain Impersonation Spoofing** If the above method doesn’t work, then impersonating it is another technique cybercriminals employ. They would often set up a domain that has similarities to the original and use that to try and trick recipients. ### **Email Display Name Spoofing** In display name spoofing, an attacker attempts to trick its recipient by forging the display name of a trusted user. Anyone can spoof someone else’s display name simply by creating a new account and applying the same name as the person they’re impersonating. ## **How Spoofing Can Affect Your Reputation** Although a company or brand can’t be held liable when attackers impersonate their email addresses and domains, such actions can still have a negative impact on their reputations. Left unchecked, people will start seeing your brand as negligent given how they could just let these actions continue. Allowing cybercriminals to repeatedly use the identity of your company to trick others will affect the effectiveness of your efforts in email marketing. Consequently, your business will suffer if you leave things as-is without taking the right actions. ## **Protecting Your Brand Reputation With Authentication Protocols** The good news is that there are techniques you, as an email sender, can start applying today to effectively protect your reputation against email spoofing. Experts have come up with technologies that will give email services the ability to identify senders. ### **Authentication Protocol #1: SPF** Sender Policy Framework, also known as [SPF](https://www.mailmonitor.com/word-on-the-street-spf-records/), is one of the first email authentication protocols email marketers use to help mail servers confirm sender identities. ### **Authentication Protocol #2: DKIM** DomainKeys Identified Mail, also known as [DKIIM](https://www.mailmonitor.com/word-on-the-street-dkim-records/), is the second most common email authentication method that aims to identify forged email headers as well as the content. ### **Authentication Protocol #3: DMARC** The third type of email authentication protocol available is the Domain-based Message Authentication, Reporting, and Conformance or [DMARC](https://www.mailmonitor.com/word-on-the-street-dmarc-records/). ### **Authentication Protocol #4: BIMI** Brand Indicators for Message Identification ( [BIMI](https://www.mailmonitor.com/word-on-the-street-bimi-records/)) is one of the newest standards that provide senders and email service providers additional protection against email spoofing. ## **Conclusion** Email spoofing is one of the most prevalent fraud techniques cybercriminals use today to trick people into giving up important information. Fortunately, there are email authentication protocols available that let servers verify the identity of the sender before accepting their message. The four available standards today are SPF, DKIM, DMARC, and BIMI. Applying these protocols should help improve your email deliverability as well as your sender reputation as a legitimate email marketer.
