The End of the Single Email Era: Why Burner Addresses Are Essential for Security

TL;DR: Relying on one main email address is increasingly risky due to data breaches and spam. By using a catch-all email system with a custom domain, you can create unlimited burner email addresses on the fly. This helps track and manage compromised accounts, reduce spam, and protect your privacy by easily discarding or replacing problematic emails, all for a minimal cost with Google Workspace.

As the security of our personal information becomes increasingly compromised, relying on a single, primary email address for all digital activities is no longer viable. Instead, utilizing a catch-all email system, like the one available through Google Workspace, offers a scalable, and manageable solution to protect personal data and combat email-related threats such as data breaches and spam.

In today’s digital landscape, email addresses are a prime target for hackers, data miners, and other malicious actors. Many users rely on a single email address for everything — from personal correspondence to signing up for services like social media, e-commerce, and banking. This creates a significant vulnerability, as any compromise of that email address could expose a vast amount of personal data. Furthermore, companies often sell or share email information with third-party data mining companies, linking our personal email addresses to data breaches on the dark web. The consequences are clear: once your email address is compromised, you are left vulnerable to phishing attacks, identity theft, and spam.

To combat this issue, I’ve implemented a simple yet highly effective solution using Google Workspace’s basic plan, which costs just $6 a month. With a custom domain and the configuration of Default Routing, I can catch all emails sent to any address on that domain. This feature allows me to create unlimited “burner” email addresses without actually setting them up. For example, if I’m setting up an account at the library, I can use library@mydomain.com. All emails sent to that address will be delivered to my main inbox, without needing to manually create a new email account.

This setup is significant for several reasons:

1. Unlimited Burner Emails: I can generate an unlimited number of email addresses on the fly, each specific to the service I’m using. Whether it’s facebook@mydomain.com, amazon@mydomain.com, or tiktok@mydomain.com, I can keep these addresses distinct and compartmentalized.
2. Spam and Data Breach Tracking: If one of my email addresses is compromised in a data breach, I can immediately identify the source. For instance, if facebook@mydomain.com is part of a dark web breach, I’ll know it was Facebook’s security that was compromised, not another service.
3. Mitigating Spam: If I begin receiving spam to a specific burner email, such as facebook@mydomain.com, I can easily “kill off” that email by setting a filter to automatically delete or trash any incoming messages to it. I can then create a new burner email, like facebook2@mydomain.com, and continue managing my accounts with minimal disruption.
4. Privacy Protection: With burner emails, I reduce the likelihood of any single email address being exposed or sold to data mining companies. Each service gets its own address, making it harder for third parties to track and link my activities across multiple platforms.
5. Enhanced Privacy with Multiple Domains: Google Workspace allows you to add up to 30 different domains to a single account. By using different domains for various services, you can further protect your identity and add an additional layer of privacy. For instance, you can dedicate one domain specifically for social media accounts, while another can handle personal services like rent, banking, or utilities. This not only helps reduce the visibility of your primary domain but also makes it harder for third parties to track your activities across platforms. Having multiple domains also keeps people guessing, which is increasingly important as we need to better safeguard our data in today’s digital landscape.

In summary, this method not only protects personal information by reducing the risk associated with data breaches, but it also provides an efficient way to manage and track email traffic. As email security threats continue to rise, adopting a system of burner email addresses — easily managed through a tool like Google Workspace — ensures a safer, more controlled online experience. Relying on just one primary email address is no longer enough; a scalable, compartmentalized approach is key to maintaining digital security in today’s world.

Here is the screenshot of how you set up the default routing aka catch-all in Google’s Workspace:

On the left hand panel of your admin console in Google Workspace click on Apps > Google Workspace > Gmail > Default Routing:

You’ll want to create a regular expression (regexp) that matches any username for your domain. A typical regexp for this would look like:

^[A-Za-z0-9._%+-]+@your_domain_here\.com$

This pattern allows for any combination of letters, numbers, and special characters before the @ symbol, ensuring you catch all email addresses sent to your domain.

I also prepend the subject with [x] to make the emails stand out. For example, if someone sends an email to any_username_here@mydomain.com, it will be forwarded to my main email address with the subject appearing as [x] Lunch tomorrow? This helps organize incoming emails, making it easy to recognize which domain and username the email was addressed to.

To configure this, use the “replace recipient” feature in Google Workspace, specifying your main email. This will automatically forward any email sent to @your_domain_here.com to your primary email address, with [x] prepended to the subject for easy identification.
