Proton Mail Plus, a premium email service, is currently being offered with a 40 percent discount, bringing its price down to 36 euros for the first 12 months of subscription. Along with this discount, subscribers receive a 40 euro gift card, but only if they do not use the 30-day satisfaction or refund guarantee. This gift card can be used on various platforms such as Amazon, Carrefour, IKEA, Uber, and Zalando, and it is sent to the user's email after the first month of their subscription. Proton Mail Plus provides users with 15 gigabytes of storage and includes end-to-end encryption by default, ensuring that messages are secure from the moment they are sent. It also allows users to set up alternate email domains and offers smartphone applications for both iOS and Android. Based in Switzerland, the service prioritizes cybersecurity and is designed for both personal and professional use. The service includes tools such as the Easy Switch feature, which helps users migrate their email from other platforms like Gmail, iCloud Mail, Outlook, and Yahoo! Mail. There's also a Proton Bridge function that allows Proton email addresses to be integrated into existing email accounts on iCloud Mail, Outlook, or Thunderbird. Additional features include calendar tools for organization and managing notifications. Proton Mail is often considered a serious alternative to Gmail, offering encryption that is accessible to all users. However, to fully take advantage of its features, a paid subscription is required. The encryption system used between Proton Mail users is based on private and public key pairs, ensuring that messages are fully encrypted and cannot be accessed by third parties, including Proton itself. Users can also set up automatic deletion of emails after a specified period, providing further control over their digital communications.
