Temporary email can improve privacy in certain situations because it reduces the number of websites that receive your primary email address.
Suppose you use the same email address on dozens or hundreds of websites.
That address becomes associated with a large portion of your online activity.
Using separate or temporary addresses for appropriate short-term interactions can reduce that connection.
However, Temp Mail should not be treated as complete anonymity.
Websites and online services may still collect information such as IP addresses, browser information, cookies, device information, and usage data.
Temporary email protects one piece of information—your permanent email address—but it does not automatically make all online activity anonymous.
