  • Zero Access to User Data
    ProtonMail does not have access to user data or emails. This means that even ProtonMail cannot read your emails, providing an additional layer of privacy.

  • Paid Plans
    Advanced features and additional storage require a paid subscription, which may be a hassle for users looking for a completely free service.
  • Search Limitations
    Due to end-to-end encryption, the search functionality in ProtonMail is limited compared to other email services, as the search can only be performed on email subjects, not the content.
  • Compatibility Issues
    ProtonMail's encryption might not be fully compatible with other email services, potentially causing issues with sending and receiving encrypted messages.

    While DeepSource provides customizable features, there may be constraints and limitations that affect highly specific or niche requirements.

    For some projects, integrating DeepSource into existing workflows may be complex and require additional setup and maintenance efforts.
