1. Proton Calendar: Set date by day, month and year

   When creating an event in Proton Calendar, it would be great to be able to select the day, month and year separately. On the web / desktop app, you can scroll through by month which is somewhat acceptable, but on iOS, you have to scroll day by day. Very cumbersome if you are trying to add an event a year or more into the future.

2. Mail extension for browser

   A mail extension for browsers like the Proton Pass extension.
   The extension should show a counter of unread mails and provide a preview when clicking the extension icon.
   So that you can see if new mails arrived even without opening the Mail UI in a tab.

4. (Current) Critical Security Vulnerability: Missing Default-Deny Policy - Why Whitelists Fail Against Zero-Click Exploits (State Trojans)

   (Current Text) April 26, 2026
   Dear Proton Team,

   Currently, Proton Mail under (Filters) "Blocked and Allowed Senders Lists" offers only a whitelist as a positive exception in a system that standardly accepts everything ("Default-Allow"). The "Allow" function serves merely to move important emails back from the Spam folder to the Inbox; it does not prevent the receipt of emails from other domains. The "Block" function serves only to block known, malicious senders.

   The fundamental security problem is that for users who need to protect themselves against Zero-Click Exploits (e.g., advanced state trojans like Pegasus or similar spyware), this "Default-Allow" model is fundamentally insufficient and dangerous. An attacker can register thousands of domains or use hacked servers to send malicious emails. A "Block" list can never cover all future, unknown attackers; as soon as a new, malicious domain is created, it is not on the list, and the email is accepted. Furthermore, as long as the Proton server accepts every connection from an unknown domain (even if it is later moved to Spam), there is a critical risk that a Zero-Click Exploit could be executed during the processing phase, such as rendering images, parsing metadata, or analyzing attachments. The malicious code does not even need the user to open it; it can compromise the email client or server infrastructure as soon as the data touches the server. Many users mistakenly believe that an "Allow" list automatically blocks everything else. Technically, this is not the case. The current list is merely a filter ensuring that certain emails do not land in Spam, not a firewall that cuts off access for everyone else.

   I therefore demand the introduction of a separate, explicit setting "Allow Only Permitted Senders" that fulfills the following technical requirements. First, the whitelist must offer flexible granularity by supporting both individual email addresses and entire domains. This allows users to define permitted senders with two distinct levels of granularity to balance maximum security with practical usability. Individual email addresses are essential for high-security scenarios where only a specific person is trusted (e.g., john.doe@company.com); this prevents access even if other accounts within the same domain are compromised. Entire domains, on the other hand, serve for the efficient management of trusted organizations or partners (e.g., @trusted-partner.com) and allow all current and future senders from that domain without manual maintenance. The system must evaluate incoming mail against both lists, with a specific address rule taking precedence over a general domain rule if conflicts arise.

   Second, server-side rejection at the TCP/SMTP level is required. The server must immediately reject the connection before any data transfer if the sender is not explicitly on the whitelist. This requires validation already during the SMTP handshake, ideally immediately after the EHLO/HELO command or at the latest before the MAIL FROM command. If the sender is not allowed, the server must immediately terminate the TCP connection or return an SMTP error code (e.g., 550 Access Denied or 554 Transaction Failed) before the actual email data transfer (DATA command) begins. No data packets containing potential exploits may be received; the server must not buffer or analyze the email content even temporarily if the sender is not on the list. The connection must be severed at the entrance so that no data packet containing a potential exploit is received by the server infrastructure.

   Third, full user control must be guaranteed. Users must be given the opportunity to completely close their digital gate ("Air-Gap" principle for email) without relying on infinite and never-complete blocklists. The responsibility for maintaining the whitelist lies with the user; this is the principle of every high-security system.

   Proton advertises worldwide with "maximum protection" and "end-to-end encryption." Yet, without a "Default-Deny" option that supports both address and domain whitelisting, the door remains physically open to unknown attackers. With this function, Proton would be the only commercial email provider enabling users to protect themselves against state surveillance and zero-day attacks through strict perimeter security. For journalists, whistleblowers, and activists, this is not an optional comfort feature, but a matter of survival. The ability to whitelist entire domains simplifies communication with teams, while the option to whitelist single addresses ensures precision against targeted attacks.

   Please evaluate this request for technical feasibility and prioritize its integration into the roadmap for security updates. Proton should offer this choice to substantiate its position as the world's safest provider.

   Thank you for your work on a safer internet.

5. newsletter digest

   Creating a daily or weekly digest message of newsletters. I can see the implementation being like an automatically generated email (opt in) that takes all the sender addresses and subject lines from every messages sorted into the newsletter view and delivered back into the inbox. This would condense messages quickly to make sure nothing important was missed and allow you to skip over everything else. This would be EXTRA useful if newsletters could be completely removed from the inbox view, or is a new -newsletter view was created. Really cut down on the clutter without the chance of missing something or something being misfiled

6. Invert Newsletter View

   I appreciate how the newsletter view concentrates the noise to one place but what would be way more helpful is a the view of all the messages that are not in the newsletter view. If either the messages in the newsletter view were excluded from the inbox or even just a new view that was the inbox sans -newsletter would be amazing. this would allow the important things wouldn't be buried in the newsletters.

8. Critical Security Vulnerability: Missing Default-Deny Policy – Why Whitelist Fails Against Zero-Click Exploits (State Trojans)

   Dear Proton Team,

   Currently, Proton Mail under "Blocked and Allowed Senders Lists" offers only a whitelist as a positive exception in a system that standardly accepts everything ("Default-Allow").

   • The "Allowed" function serves merely to move important emails back from the Spam folder to the Inbox. It does not prevent the receipt of emails from other domains.

   The Fundamental Security Problem: For users who need to protect themselves against Zero-Click Exploits (e.g., advanced state trojans like Pegasus or similar spyware), this "Default-Allow" model is fundamentally insufficient and dangerous.

The current list is only a filter ensuring that certain emails do not land in Spam. It is not a firewall that cuts off access for everyone else.

   The Demand: A True "Strict Allow-Only Mode" (Default-Deny Policy) I demand the introduction of a separate, explicit setting "Allow Only Permitted Senders" that fulfills the following technical requirements:

   • Server-Side Rejection (TCP-Level Blockade): The server must immediately reject every connection from a domain/sender that is not explicitly on the whitelist (e.g., with 550 Access Denied) before the email data is even transmitted.

   • Full User Control: Users must be given the opportunity to completely close their digital gate ("Air-Gap" principle for email) without relying on infinite and never-complete blocklists.

   Why Proton Urgently Needs This: Proton advertises worldwide with "maximum protection" and "end-to-end encryption." Yet, without a "Default-Deny" option, the door remains physically open to unknown attackers.

   • Competitive Advantage: With this function, Proton would be the only commercial email provider enabling users to protect themselves against state surveillance and zero-day attacks through strict perimeter security.

   • Existential Necessity: For journalists, whistleblowers, and activists, this is not an optional comfort feature, but a matter of survival.

9. Highlight starred mails

   When you add a star to your mail, it should change the background colour in the list of mails.
   It should also be possible to arrange your mails so that the starred mails are on top of the list (sorted by date), and regular mails are at the bottom (also sorted by date).

   This would highlight the starred mails. I am not a fan of the starred mails mixed in between regular mails.

10. Support more than 4 Security Keys

    Proton supports only 4 hardware security keys - this is not enough. Especially since using biometrics counts against the 4 key limit. I have three desktop computers which run my Proton accounts, and I have mobile devices which require 1 key. So I can't use the biometrics option without forcing a game of musical chairs with my security keys. I'm forced to continue using and subscribing to my 1Password account rather than Proton Pass until this limit is increased.

    I want to ensure my account is not delete due to inactivity as per https://proton.me/support/inactive-accounts

13. Dynamic email / alias addressing

    This would be most likely against the way email is working nowadays, but could every email I create be sent from dynamically created alias so I do not own a real, static email address as such and I am not prone to any spam, phishing attemps and so on?

    I could imagine me, my digital identity, my emails being of a digital pod which could be contacted only when I would have made a first, initial attempt.

    I am not even sure if this technically makes sense,

17. Show time zone names (or custom labels) in the calendar view, not just GMT offsets

    When two time zones are enabled, both columns are only labeled with their GMT offset. Example: Europe/Vienna and Africa/Johannesburg both display as "GMT+2" during European summer time — completely indistinguishable. In winter the offset differs by one hour, but "GMT+1 / GMT+2" still doesn't tell you which column belongs to which zone.

    Please show one of the following next to (or instead of) the offset:

    The IANA city name (e.g. Vienna, Johannesburg), or
    A user-defined label per zone, or
    The standard abbreviation (CET/CEST, SAST).

19. Importing email from Gmail -> don't turn folders into labels

    The mass import from Gmail to Proton Mail was great....except my extensive set of folders/sub folders got turned into one massive list of labels.

    Please either make

    (1) an option where a label category can be converted to a folder; or
    (2) make it so Gmail folders are imported as folders with their nesting folders under them.

    Having to convert everything manually is excruciatingly tedious.

    Thank you for your consideration!

20. server-side integration for proton mail

    Proton Mail lacks a developer-facing event/API platform for backend automation. I need machine-to-machine notifications for incoming email (webhooks/events) and programmatic mail access without relying on Proton Bridge or desktop clients.
    Maybe allow users to opt into developer integrations (webhooks/API access) for specific addresses or folders, even if that requires a different trust model or user-granted application permissions.
    Or api access via user-held keys.
