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.
Works4.5I use ProtonMail for secure financial communications, valuing its auto-encryption and custom hashing. Setup was easy, and it's stable. I wish free Proton Pass integration existed. Overall, it's a cost-effective, highly secure email solution.
