I would like a similar experience in the browser that we have with the mobile app. Set an expiration where the user can still unlock quickly with PIN.

A trusted computer browser stores the main logon cookie with no expiration. But this cookie only has an encrypted blob that cannot access the mailbox alone. The 2nd cookie set to expire in X minutes/hours must be combined with a user supplied PIN, and that will decrypt the non-expiring main cookie blob, which logs the user back into the mailbox.

1 user, 1 domain = 48€/year
If you need 2 users, 1 domain = 150€/year
Why a so big price increase when you need 2 users ? Could you have an better offer, for example at 70€/year. Seems more logical.

Best regards

ProtonMail Bridge has bugs integrating with the Mailspring email client. The Mailspring team have expressed interest in working together to get these issues resolved. If the bugs could be fixed and the Bridge could get working with Mailspring it would be a great productivity booster!

The pssibility to make sub-folders for storing emails would be appreciated. Ie. folders that have parent folders and the folders would show up in a hierarchial tree where the folders are currently displayed.

Especially for corporate users filing emails hierarchialy is of great help.

Whenever we send an email protonmail always attaches protonmail.com as a comment to the signing as well as the gpg key. I feel this is forceful advertising by protonmail. As of now there is no method to remove the same.

If mails are grouped, only those should be grouped that a) mention / quote another mail OR b) if the mails arrived within x minutes.

Because as it is at present with me mails are grouped which were sent years(!) after each other. They also have nothing at all to do with each other. Only because both have the same title.

Country config only give access to the basic servers even for Plus subscribers. This limits the number of IPs which are randomly cycled through by a Plus user and takes away a lot of incentive to upgrade.
It would be useful to have Plus specific country config files.

One of the major complaints I have about your otherwise excellent product is that message notifications on the mobile app aren't updated if I read, delete or archive the e-mails via the web inbox.

For example, if the mobile app notifies me of a new e-mail and instead of reading it on my smartphone, I go to the web and read it there, the mobile app notification doesn't acknowledge that. I have to read or manage the e-mail on the smartphone even if I already read it on the website. It's makes for a lot of unnecessary double work.

Please implement more keyboard shortcuts for managing mail message. An example would be keyboard shortcuts to open the "Move to folder" and "Apply label" dialog. This is similar to GMail's shortcut, when you have a message(s) selected and press the "v" key. Currently I have to mouse around to do this, and organizing messages is such a core feature, I don't think using the mouse each and every time should be necessary.

Emailed notifications of all login attempts, successful or not.

When available, these notifications should go to a separate notifications email rather than dropped in the protonmail inbox.

If "advanced logging" is enabled, it should also add the IP address of the login attempt.

(Otherwise someone breaking into a protonmail account would see that appear in the protonmail inbox, and naturally would be able to delete the notification mail before the rightful owner can log back in.)

Can you allow me to "trust" a device - like other websites do - so that I only need my credentials, but not need my 2FA code everytime I log on on my own laptop?

The Lightning Network is in beta, but it allows for instant payments (no confirmations) and almost 0% fees, provided the user has a channel open. You already accept Bitcoin... and the Lightning Network is a major upgrade to way people will use BTC to make payments. If you do it soon, you will also get a P.R. boost, as it will inevitably be mentioned in the Bitcoin media.

So far we can set loading embedded and external images on or off. It would be beneficial to set the option per domain/sender.

Can i used last remembered password or connected paypal to reset password i need it to get back in my account. Im using the same device from the same location.
