ProtonMail Reviews Summary
Author infoRatingReview Summary
Media Content Creator Intern4.0I use ProtonMail primarily for sending anonymous emails for activist work. I appreciate its trustworthiness and ease of use, though it's mostly favored by tech-savvy users. It could benefit from broader appeal to enhance its popularity for general use.
