Conclusion
In recent years, with the widespread use of services like LINE, opportunities for individuals to use email have decreased. Nevertheless, situations such as online shopping still require an email address.
The free plan of Proton Mail has certain limitations, such as a maximum of 150 messages per day and 1 GB of storage, but it does not display ads and is more than sufficient for personal use. It can also be used as a secondary email address.
With the paid plans, various restrictions are lifted, and additional features become available. Moreover, you gain access to other Proton services beyond Proton Mail, such as calendar, cloud storage, VPN, password manager, and wallet, making it a cost-effective option.
For those who value privacy, this is an ideal email service. Start by creating a free account and try it out for yourself.
