1. Improved week view in mobile calendar

   aCalendar+ has the best week view concept that I've seen. It arrays the days in a grid of 8 boxes, the last one being a miniature month view, in either a landscape or portrait view, and it only lists appointments, not every time slot of every day. Proton Calendar only has a portrait view with 7 extremely thin columns, which can be very tedious.

   Proton needs some more options in this area! The 3-day view is better, but it only lets you see a couple of days ahead, not getting the picture for the full week in one glance.

2. Tags and sub-tags

   I would love it if we could have sub-tags. For example, Hawaii would be a tag nested under Travel. Although folders allow subfolders, I think tags are so much more nimble and flexible.

4. Proton Mail row view: preview pane, and default goes to next message

   When viewing emails with row view, I have two suggestions
   - It would be useful to have a preview pane in row view mode.
   - After processing an email the window goes back to the main page, so I need to click on the next message. It would be better if by default the next message was displayed instead, or at least to have an option to choose

5. Incorperate proton calendar with ubuntu top bar

   Right now, there is no integration with ubuntu outside of the app. It would be extremely nice to not have to start the app every time I wish to check my calendar. An integration into ubuntu's top bar akin to the current calendar gui would be ideal. This would massively streamline my usage of proton calendar. Even a small extension in the top bar would be useful as well.

6. Send encrypted e-mails to non-Proton Mail users without password

   Currently, Proton Mail users can send secure e-mails to non-Proton mail users user password protection. This feature adds complexity to the process. Can you provide an alternative method which doesn’t require a password but instead uses a 2FA method to verify the recipient’s e-mail address (similar to applictions such as Securemyemail),

7. Easy switch for registered emails from gmail to proton

   Following the ability to connect my Proton Mail with my Gmail, I'd love suggestions in my inbox that offered me an easy way to change the email address associated with third parties.

   For example, I have an account with Zalando. It would be awesome if, after an email from Zalando, there is an way for me to click-through to Zalando's account management screen where I can update my email. Providing this option for third parties who offer change of email addresses.

   I'm not sure if this could be done in a way that doesn't intrude on privacy, but would be great if possible and really help me with migrating my life (not to be dramatic) over to Proton's ecosystem.

8. 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.

10. 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.

11. 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.

12. (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.

13. Strike agenda items

    When deleting an event in the Proton Calendar, I still want to be reminded that it was there originally. Is it possible to offer two kinds of delete:
    (A) strike through the event (so it is still visible in the calendar, but now the title is in strike through), or
    (B) permanently delete the event?

14. Make Auto Reply Faster to Access and Place Notification at top of Mail Window

    The Auto Reply / Out of Office feature should be faster to access within the Mail app or window instead of navigating to All Settings first. Then, when the Auto Reply is active, a static notification should appear at the top of the window reminding the user that Auto Reply is active. This is common in other major mail services.

16. 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

19. hover shows actual email address

    Proton Mail used to display the email address of the sender when hovering over the sender's name in a list. This features seems to have disappeared !
    
    It is especially useful when an email appears which could be spam with a faked FROM name to show the FROM address. Then you can see Amazon / Ebay/ PayPal / YourBank is actually lyingthievingspammer@123456.co.jp or whatever.

    Another post mentions similar about links.

    This is a really useful feature.
    Bring it back ! Pleeeeease !
