  1. Allow 'All Mail' to be chosen as the default folder

    The tedium of using ProtonMail because it reverts to the inbox is annoying. New messages filtered into folders are not noticeable from the inbox. Please allow 'All Mail' to be set as the user's preferred view.

  2. Add built in S/MIME email signing

    It would be nice if mails could be, by default, signed with an S/MIME.
    Proton mail already supports signing mails with G/MIME, but G/MIME doesnt add the little green checkmark on gmail (it just makes my message get an attachement with the key, and get sent to spam).

  3. Please add all functionality in the main mail app to mobile (snooze, etc)

    The descrepancy in functionality berween PM instances has become problematic for anyone who rotates through thwm daily due to workflow. As a side note, being able to access my paid account on the windows app but not my free account is ridiculous.

  4. Drag Labels to Messages

    I’d love to see a more fluid drag-and-drop workflow for labels in Proton Mail.

    In list view, drag a label from the left sidebar onto a message to apply that label. If multiple messages are selected, dropping the label onto one of the selected messages would apply it to all selected messages. When viewing an individual email, dragging a label onto the open message would apply it there as well.

    This would make organizing mail much faster and more intuitive, especially for users who manage workflows heavily with labels. It also feels like a very natural desktop-style interaction that many…

  5. ICS import fails when VEVENT uses custom TZID ("Customized Time Zone")

    Description

    Importing an .ics file into Proton Calendar fails when a VEVENT references a custom timezone (e.g. "Customized Time Zone").

    This appears to happen when the TZID parameter is used directly in event fields.

    Example

    Example snippet from the ICS file:

    BEGIN:VEVENT
    DTSTART;TZID=Customized Time Zone:20260316T083000
    DTEND;TZID=Customized Time Zone:20260316T093000
    SUMMARY:Example Event
    END:VEVENT
    Expected behavior

    Proton Calendar should either:

    resolve the custom TZID via the VTIMEZONE definition in the ICS file, or

    fall back to the provided UTC offset.

    Actual behavior

    The import fails because the custom timezone cannot be processed.

    Context

    ICS files exported from calendar clients such as Outlook often…

  6. Support pkpass

    With support for pkpass files in Proton Email, users could store and manage their passes (such as boarding passes, loyalty cards, and event tickets) directly in Apple Wallet or Google Wallet, for example.

  7. Calendar app icon to display the current {day of week} and {day of month}

    Background

    The Proton Calendar app on iOS (and presumably Android )currently appears like a blueish/purple square with a small "31" in the bottom right corner. The "31" is static and doesn't change.

    The official Apple Calendar app icon has the name of the day (e.g. "SAT") and the day of the month (e.g. "13") on the icon itself, making the app icon useful at a glance without even requiring the user to open the app.

    Proposal:

    It would be very cool and very useful if the "31" on the Proton Calendar app icon actually changed to represent the current day…

  8. Cross-platform synchronization

    I’ve noticed a persistent sync lag between the browser version and the iOS app. Not a lag i guess, since it never happens.

    Even after I’ve cleared my inbox on my computer, my iPhone still shows a notification badge for those same emails. It seems the app is relying on a manual pull/refresh to update the badge rather than a server-side push.

    It would be great if the Proton Mail app could sync the "read" state in the background so I don't have to open the app just to make the red bubble go away.

    Is this on the roadmap…

  9. Allow non-Proton users to edit Calendar

    It would be very helpful if a calendar could be shared with non-Proton users in edit mode. Now it is only possible to allow external users to view a calendar, but they cannot add items to it.

    Yes, it could be achieved by everybody using the Proton Calendar app, but as everybody has their own app, it would be very nice to have a standard integration to allow everybody use their own agenda app.

  12. Feature request: always show each link's real destination URL

    Feature request: always show each link's real destination URL.

    Please display the actual destination of every link directly at the link (e.g. above or beside the link text), not only on hover or long-press, and visually flag the destination in red when the destination's host does not match the hostname named in the visible link text.

    Generic call-to-action text names no hostname, so there is simply nothing to mismatch there; the value is that the real destination is still shown in plain sight.

    This closes the link-text-mismatch gap that authenticated phishing exploits — e.g. the Jan 2026 SendGrid campaign, whose…

  13. Contact Folders (separate from Groups)

    Currently, Proton Mail allows creating Contact Groups, but these work like mailing lists: selecting the group sends an email to all members at once. That's useful for mass messaging, but it doesn't solve the need to simply organize contacts into categories.

    Proposal:

    Add the ability to create Contact Folders, where each contact inside the folder remains completely independent (selecting the folder does NOT send an email to everyone in it, it's purely for visual organization and easier searching)

    Example use cases:

    Family: Mom, Brother, Wife
    University: University support, Classmates, Professors
    Work: Boss, Team, Clients

    Each contact remains independent, folders are…

  14. Provide the ability to edit the subject line of an e-mail

    Often an e-mail comes with a subject line that doesn't completely describe the content. For example, in a newsletter e-mail there may be several articles and the subject line is the first article. I may want to save the e-mail because of the second article. When this happens, I forward the e-mail to myself so I can change the subject line, but then I lose who it came from. Outlook has provided the capability to edit the subject line for many years and I'm surprised I haven't seen this feature in other e-mail applications. Seems like a simple thing to…

  16. Add Sender to Existing Filter

    I like to use my filters for categories of senders, not just individual filters for every sender. It would be nice if we can click the "Filter" button and choose the option to append the selected email's sender or Subject etc. to an existing filter.

    For example, I like to put all my emails related to airline points in the same folder. Having 5 filters for different airlines makes my filter list cumbersome to go through, so I combine them into one filter. If I have an existing filter that is already moving New Zealand Air emails to my Points…

  17. Move the Undo Dialogue Box

    When you archive or delete an email, or do anything really, a small yellow dialogue box appears at the bottom of the list of emails to offer you the option to Undo the action. This dialogue box floats atop the subject line of the bottom most email in the list. So if you are trying to manage about 1-page of emails in your inbox, that box stops you in your tracks until you either manually exit it, or wait out its timer to fade away.

    It's a minor nuisance, but a very real one. The last email in the inbox…

  18. Mute a conversation/thread

    Like in other email providers, it should be possible to "mute" a thread.
    By doing so, other emails coming in the thread would not trigger a notification, nor put back the archived thread in the inbox.

  19. Unlimited custom‑domain forwarding for paid Proton Unlimited Mail accounts

    Unlimited custom‑domain forwarding for paid Proton Mail accounts
    Brief request
    Since switching to Proton Mail, I’ve noticed a missing feature: the ability to forward an unlimited number of addresses from my own domain (e.g., whatever@mydomain.com).
    Currently, for Proton Unlimited, each forwarding address must be one of the 15 “authorized” addresses listed in the account settings. For a paid plan this restriction feels annoying.

    Your strategy, is may be to push people to subscribe for Proton Family, which has a limit of 90 adresses e-mail/alias. But come on, you push too far.

  20. Scheduling poll (like doodle) but with quadratic votes and tentative events

    To organize an event, it is often necessary to poll a group of people about possible dates. This problem is solved by Doodle (https://doodle.com/), but I'd like to see this as a proton-native operation.

    Specifically, a poll could look like this: You click on a separate "Event Poll" action button under "New Event", enter the addresses of people you'd like to participate in the event, and select some date options. The invited people get emails with a link to a page where they can vote for specific times. All date options show up in your calander with a…
