Gmail offers a system that allows users to identify which company has shared their personal data through the use of aliases in the email address. This feature, available for any account, consists of adding text after the user's name and before the at symbol. For example, [email protected].
How the alias works in Gmail
The system recognizes any email sent to an alias address as valid and automatically redirects it to the main account. It is not necessary to create new accounts nor are there security risks when using aliases, since only the identifier before the at symbol is modified. The method does not require advanced configurations or technical knowledge.
In case of receiving spam addressed to an alias address, it can be deduced that the data leak or sale came from the platform where that alias was used. Gmail allows filtering emails automatically according to the alias, facilitating the management of unwanted or suspicious messages.
Limitations and traceability
Some companies automatically remove aliases when processing email addresses, which hinders the traceability and tracking of possible leaks. However, the use of aliases does not alter the user's main address nor affects the functioning of the email. All emails with aliases are redirected to the usual inbox.
Alternatives with temporary accounts
In addition to the alias system, there are temporary email accounts that provide valid addresses for a period of 10 minutes to 24 hours. These services generate random addresses to receive messages for a limited time and allow access to verification codes or perform registrations without exposing personal email.
When using temporary emails, the main address is not stored in third-party databases. This option is useful for those seeking greater privacy in specific registrations or tests of digital services.
