Customer Reviews
Users widely praise Proton Mail for its strong security, privacy, and clean, ad-free experience. Many appreciate the straightforward interface and reliable protection against malware and tracking. However, opinions are mixed on several aspects: while some find the free tier adequate, others criticize the 1GB storage limit and the need for a paid subscription to delete spam. The mobile app receives both positive and negative feedback—some users enjoy its smooth performance, while others report frequent freezes, failure to refresh, and deceptive notification badges designed to prompt upgrades. Cross-device access is valued, but recent changes requiring payment for the desktop app have disappointed former premium users. Features like the inability to delete multiple emails at once and complex profile picture changes frustrate some, though the core encryption and privacy focus remain highly regarded. Overall, a secure choice with notable trade-offs in free functionality and app stability.
