Reviewers report that Proton Mail receives a mixed but generally improving reception, with a growing number of positive experiences despite persistent frustrations. The overall sentiment has trended upward since mid-2025, with average ratings rising from 2.97 stars in October 2025 to 3.53 stars in June 2026, despite a dip in August 2026. While nearly half of the mentions are negative, primarily citing technical issues, poor customer service, and restrictive features, over 2,600 reviews express satisfaction, especially around privacy, interface simplicity, and reliability. Many users praise Proton Mail as a trustworthy alternative to mainstream providers, though recurring complaints about account access, app stability, and hidden costs continue to surface. The balance between positive and negative feedback remains uneven, but the upward trend in ratings suggests improvements in core functionality and user experience over time.

How it has changed over time

The service has shown gradual improvement since late 2025, with ratings climbing from 2.97 stars in October to 3.53 stars in June 2026. The dip in August 2026 may reflect a temporary spike in issues, but the overall trend remains positive. Early complaints about account creation and login failures have been less frequent in recent months, and users note fewer disruptions in core email functions. This suggests that Proton has addressed some long-standing technical problems, though new issues like app instability and upgrade prompts continue to appear.

Practical takeaways

For users prioritizing privacy and security, Proton Mail remains a compelling choice despite its flaws. It’s best suited for individuals who are willing to tolerate minor interface quirks and occasional technical hiccups in exchange for strong encryption and data protection. Those who value simplicity and control should consider it, especially if they’re looking to leave mainstream email providers. However, users should be cautious about hidden costs and ensure they understand the account setup process before subscribing.
