Simplify and Optimize Date & Time Input for Appointments
Mask (live formatting while typing)
As the user types, raw numeric input is automatically formatted in real time. Example: typing 1000 instantly displays as 10:00 while still in the field.Auto-Format on Blur (on leaving the field)
When the user leaves the input field, shorthand date entries are automatically expanded into the full formatted date. Example: 220226 → 22.02.2026Raw Input Parsing / Smart Date Recognition
The system intelligently interprets numeric raw input and recognizes it as a date without requiring the user to type separators manually. Example: 220226 is parsed and recognized as the date February 22, 2026.Users…

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…

Calendar Booking page for teams
A booking page for teams checks the availability of several of our employees.
There should be two options:
a) All team members must be available at the scheduled time. The appointment is scheduled for all employees and the client. Example: There is a dedicated team that works with a client. The client would like to schedule a meeting when all of our colleagues are available.b) At least one team member (any member) must be available at the scheduled time. The system automatically selects an available employee and schedules an appointment for them and the customer. Example: A customer needs…

enable reminders to be sent to phone as text messages
As someone who needs strong, clear reminders that don't require me to remember to check my email and then have to click the currently oblique email reminders in proton, I would love to see the option to have event reminders sent to me by text message - as often as I need them.

Allow any email alias to be used when SMTP Submission is authenticated.
Problem Statement
The current SMTP submission authentication system in Proton Mail & Calendar requires users to authenticate with the exact email address they're sending from. This creates unnecessary complexity and limitations for power users and developers who need flexibility in email handling.Current Limitations
Single authentication constraint: Users must authenticate with the same email address they're sending from
Token management overhead: Requires creating separate aliases and tokens for each service that needs to use different email aliases
Multi-user environment issues: Particularly problematic in systems like Ubuntu where different user accounts (root vs. logged-in user) have different usernames
Developer workflow disruption:…4 votes -
Filter Export or Filter Consolidation
I am using a lot of filters to move my emails to folders automatically. Most of these filters are generated by using the ""Nachrichten dieses Absenders immer verschieben" feature. But now I have hit the 250 filters limit, and I'm not nearly done with filter creation.
The way I see it, there are two possible solutions:
1. I need to be able to export all filters, whether they are created automatically, or by hand. Export all filters as Sieve filters, which, I guess, is the format they are saved as anyways.
Using the export, I can then use external tools…4 votes -
Proton Calendar as the default app for iCal
On macOS, it should be possible to open iCal files directly in Proton Calendar. Currently, Proton Mail/Calendar cannot be set as the default application.

Allow drag and drop to sort folders/labels outside of "All Settings" menu
Every other email client I’ve used lets you rearrange folders/labels with simple drag and drop. For some reason, Proton requires you to open a separate settings menu just to change folder order, which is incredibly frustrating, especially if you reorganize often.
What’s more confusing is that you can drag and drop default categories like “Inbox,” “Drafts,” and “Sent,” but not your own folders or labels.

Reply to email with aliases
When replying to an email, and it was sent from an alias, auto select that alias, so the person knows who it is from. Having to manually select an email address can get tedious. A toggle could be added to allow this behavior or not.

Select multiple events at once in Calendar
I don't understand why this feature doesn't already exist. I imported my schedule into Calendar, but now I'm stuck with events that don't apply to me. Instead of being able to select these events all at once, I have to delete them one by one. Plus, the fact that you can't just press the “Delete” key on the keyboard to delete an event more quickly is pretty annoying.

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.

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 votes -

Reading mode for email body with the ability to choose font size and background color would have been fantastic.

Alternating row color in inbox
Also known as zebra stripes. Title says it all. Looking to see where I can enable interchanging the background row colors between two colors (white and grey).
Simple theme change to help with readability or accessibility. Pretty commonly implement in many operating systems and other products.

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 behaviorProton 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…

Update view (with columns) of Proton Mail in iOS.
Please urgently integrate the column view in Proton Mail for iOS (especially iPad) to have a modern email client view with a column for email inbox + view of email content.
Current work is not user-friendly and the current client is like something from the 90s.4 votes -
WKD
Web Key Directory is a service for automatically learning one's public key when composing a message. Integrating this would increase the amount of encrypted communication. Having WKD as a service on custom domains like OpenPGP directory does would be a nice addition.

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.

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.
