PF Mail has been introduced as a free email service, with users expressing mixed feelings about the sign-up process, particularly regarding the requirement for personal information such as home address, phone number, occupation, and household income. Some users are hesitant to provide this information, while others suggest making up details to bypass concerns. The service has been available for years, but its visibility and user engagement seem low, as many users still prefer other email platforms like Gmail. Discussions also highlight that while some users have created accounts, they rarely utilize the service, primarily using it for specific file-sharing needs. Overall, there is a blend of curiosity and skepticism surrounding PF Mail and its data collection practices.
