Balancing Innovation & Email Security in the Age of ChatGPT

ChatGPT is an open-source AI language model that can generate text like a human. But this powerful tool also poses a threat to cybersecurity – particularly in email. Take a look at the risks and how you can protect your email security with DMARC.

ChatGPT is a large language model that uses artificial intelligence to generate text that reads so naturally,


it appears to be written by a human.

Open AI’s cutting-edge technology, ChatGPT, recently took the world by storm thanks to its ability to come up with ideas and generate conversational and contextually relevant messaging automatically. So far, it’s used for things like chatbots, virtual assistants, content generation, code debugging, and possibly even a replacement for Google search. It can even translate information into other languages.

Intelligence like this can empower millions and opens up incredible possibilities for the future. It’s an exciting time for professionals and businesses. That is, unless you’re the victim of cybercrime.

ChatGPT’s Impact on Email Security

ChatGPT and similar AI language technologies have the potential to revolutionise the way we interact with machines – and each other.

But, with such powerful tools in the hands of literally anyone, they can also pose a significant threat to cybersecurity. Especially when it comes to email.

Here are some of the ways this is currently playing out:


Email Phishing Scams

Phishing scams are a common tactic used by cybercriminals to steal sensitive data, like logins to high-value systems or financial details. Typically, these scams involve sending emails that look like they’re from a legitimate source and asking the recipient to either share their personal information, or click through to a fake website where they can steal it.

With ChatGPT at cybercriminals’ fingertips, phishing emails are now easier to create and harder for recipients to spot.

Luckily, ChatGPT itself has some restrictions in place when it comes to generating crime-based content. For instance, if you ask it to write a phishing email, it won’t. But there are other ways around it – like asking it to write an email or marketing message for a particular brand. It’s largely a matter of how you phrase the command. See an example here.

Writing Automation

ChatGPT can also be used to automate the creation of phishing emails, targeting thousands of victims with unique messaging in a short time. According to CSO Online, people with more advanced technical skills “can create an infinite number of mass-produced customised communications using AIs that can learn in real time what works and what doesn’t.”

Fake Web Presence

Email scams aren’t always limited to emails either. They often include other online collateral, like fake websites, personas, or even phony profiles of real people. ChatGPT can assist in creating intelligible written content for all of these elements – quickly and freely.

This means cybercriminals can launch more sophisticated scams, in less time – at scale.

Message Translation

ChatGPT also has a built-in translation tool that’s been tested with nearly 100 languages. This enables people to target audiences outside of their mother tongue. Until now, if scammers wanted content written in other languages, they needed to hire someone to do it for them – a process that added friction to the process of launching the scams. ChatGPT dissolves those barriers entirely.

How DMARC Protects Businesses

DMARC stands for Domain-based Message Authentication, Reporting & Conformance. It’s an email authentication protocol that enables you to control how emails from your domain are handled by receiving servers when they can’t authenticate your emails. This helps you to protect your domain from being used by unauthorised people, like cybercriminals.

Check your domain

DMARC isn’t used in isolation though. It builds on other email security protocols called SPF and DKIM.

  • SPF (Sender Policy Framework): This specifies which mail servers are allowed to send email from their domain, verifying that the sender of an email is authorised to use the domain.
  • DKIM (DomainKeys Identified Mail): DKIM allows receiving servers to check that an email claimed to have come from a specific domain came from its domain owner. It does this by adding a digital signature to all emails sent from the domain name, which the recipient system can then verify in the DNS (the phonebook of the internet). A valid signature also confirms that the email hasn’t been tampered with since the signature was attached.

DMARC essentially ties these protocols together with a consistent set of policies that all email servers can understand. Even though this may sound simple in principle, it isn’t always easy to get right.

There are tools to help you set up DMARC on your domain, but it requires specialist skills not commonly known or understood. In fact, many DNS experts aren’t even familiar with the commands needed for each protocol.


It pays to use a platform like Sendmarc that can get you set up easily.

Secure Your Emails with Sendmarc

ChatGPT has the potential to shift how we do a lot of things in the future. But despite all its potential for good, the increased threat to email security is very real too. With an email authentication protocol like DMARC – and Sendmarc, which makes it easy for you to launch and manage – you can mitigate these dangers to your domain and reputation entirely… in 90 days, guaranteed.
