1. Expiration time
2.Encryption

Both are awesome features I never saw in any E-mail service.

I sent a email to a person and I wont want that email to be forwarded by him. Is there any option in our service that it make the mail to be blocked in his account only.

Add ability to blacklist domains.

Once we had Altavista. But the time passed and it was killed by Google.

Today we have Google. But we're tired.

So could Proton team make a ProtonSearch to give us an option?

It would be great if the composer window could popout to its own window, not just be popup or full screen size inside the window. On a laptop, it conceals too much of the inbox messages, which are nice to consult when writing an email.

Add option to send your email traffic through your VPN network (each email through different servers). This would add extra layer of security making it difficult to do timing based attacks (user is seen to send email and at the same time protonmail server is seen to send email to a specific address.

basic calendar. This is a business email address. we need calendars.

Along with making archiving from the message viewer on the app easier, when those emails are archived they should be marked as read.

Thanks!

Hi I would like ask about possibility create messenger as Skype but with full PGP secure end-to-end protection voice and full HD

IMPORTANT SECURITY FEATURE FOR ANONYMITY:
Seen on other email services. Delay the delivery of an email so entities that are watching your IP address cannot link you to emails sent, via your IP requests.

Provide three options depending on users urgency:
- Random 1hr
- Random 24hr
- 1 day + random 2hr

I dislike the way the other suggestion was laid out so here's a new one.

I would love to see a native ProtonMail app for Ubuntu Touch. The idea given in the other suggestion isn't enough as Libertine (the method to install desktop Debian apps) is broken on some devices. We need a native ProtonMail app for UBports' Ubuntu Touch 16.04. 15.04 is going to be deprecated soon.

Here is the other suggestion for an Ubuntu Touch app:

POP3 support:
# for acess email account by p.e. Thunderbird, that can be secured by TLS 1.3 and if wished by PGP
# demand other email accounts by PoP3, pe. from other Proton Mail accounts or from other email provider

Please add a secure storage option... Like proton dropbox with all the privacy and security of protonmail

Is there anyway a calendar could be added? Would love to have this feature

Removal of ProtonMail adverts on 'home page' - for paid members using ProtonMail for business, we aren't keen on all our staff seeing the ProtonMail adverts when logging in i.e. ProtonMail is the highest rated app, also, the ProtonMail shop is now open....etc etc

This looks a little unprofessional, and we would ideally like the option to remove it for our paid accounts. Thanks.

Bitcoin transactions fees are now too much, and it may take up to a few hours for a transaction to be confirmed. There's a payment system, which is nearly same of Bitcoin, Bitcoin Cash. Its devs have a better vision "low fees, 1 block (10 minutes) transaction confirm time." If you haven't heard of it, here (https://bitcoin.stackexchange.com/a/58969/38618) you can see that many wallets support it.

Kind regards.
