When it comes to online security, the golden rule is not to reuse passwords. However, passwords almost always travel paired with an email address, a piece of data sent in plain text on every platform and rarely given the same caution. Sharing your personal email means handing over your digital identifier, which can be used to track activities and profiles. Just as you should not reuse passwords, your primary email should not be used for every signup, especially considering that replacing a compromised address is exponentially harder than changing a password.
Why email aliases are the most effective solution
An email alias is a secondary address that forwards messages to your main inbox without exposing your real address. In case of a data breach, you simply disable the alias, and your actual email remains safe. Services like SimpleLogin, Addy.io, DuckDuckGo Email Protection, Firefox Relay, and Apple Hide My Email offer this functionality with varying levels of free access and privacy. SimpleLogin allows unlimited aliases with a custom domain, while Addy.io provides a generous free plan with 20 aliases. DuckDuckGo Email Protection and Firefox Relay integrate directly into their respective browsers, and Apple Hide My Email is natively available for iCloud+ subscribers.

SimpleLogin and Addy.io: the best for multi-device management
SimpleLogin is an open source service that supports attachment forwarding and anonymous replies. The free version includes 15 aliases per month, while the paid plan unlocks unlimited aliases and custom domains. Addy.io, also open source, offers 20 free aliases and the ability to create temporary aliases. Both services are compatible with any email address and work on all platforms. For those seeking a browser-integrated solution, DuckDuckGo Email Protection removes trackers from forwarded emails, while Firefox Relay hides the original address and blocks advertisements. Apple Hide My Email is the most convenient choice for Apple users but requires an iCloud+ subscription.

How to choose the right alias service for your needs
The selection depends on the desired level of privacy and the ecosystem you operate in. If you use Apple devices and already have iCloud+, Hide My Email is integrated into Safari and system settings. For a cross-platform open source solution, SimpleLogin and Addy.io offer more flexibility. DuckDuckGo Email Protection is ideal for those who also want to block trackers, while Firefox Relay is perfect for Firefox users. None of these services are perfect, but all represent a step forward compared to indiscriminate use of personal email. Protecting your digital identity has become essential: just as you invest in physical data security, such as expanding storage with a Sandisk Phone Drive for iPhone, your communication privacy deserves conscious investment.
