Agreed, Tutanota is much affordable in that sense. Also, not every Premuim user needs al the features that premium accounts offer, Some of us just need the alias feature, maybe some others just need more space. Instead of selling all that in a single package we should be able to buy the features we need at a smaller price.

I think something like 1 or 2 euro per months is a good price that i would be happy to pay.. I personally would pay 50 euros only if that way i could add a feature permanently to my account. etc. buy more space for life or add unlimited filter permanently to my account.

What about a offer - model in the middel - go from 30 GB to 15 GB and then half of the rest of the futures, and also pay half. 30 EURO is a lot, and you will get a lot some don't use. And we will be happy to pay 15 EURO.

As a low volume user, the free service is perfect for me but I would like to have a couple of features, particularly a couple more aliases that can be changed anytime, without limit. BUT the jump to $50 to get more aliases (that apparently aren't disposable) is too large. There should be a payment option for a token amount, $10 or $12 per yr, for those who want to contribute to the developers but want a slight enhancement of the free version.

Going from either absolutely free to $50 /yr (for a very modest increase in features) IS a large leap. I would be happy to pay $10 /yr as a combined price/donation for the version that's now free if it included a couple more aliases (that are infinitely disposable). I would only upgrade to the $50 if it had many more features, including some of those voted on here plus some of the steathy options offered for pay in other email services (like throw-away and time-limited email address).

@Petr thats something that depends from your salary. I know that protonmail needs support. I would support it but 4 or 5 euros per month is a considerable amount of money.

I don't think it's expensive. ProtonMail is not a Google or Apple, and it doesn't earn millions of euros per month, it is a start-up that needs first several years a great support of it's users and fan community. I don't see a problem in using a free account, it's not that limited as you could think, because we all got used to Yahoo, Gmail etc. ProtonMail has the bright future. And we need to invest in this future, like we invest in new technologies buying new products released every year.

I disagree with this. Email is too important for your security and privacy online not to pay for. For anyone in a developed country current pricing is very reasonable, in relation anything else you're already paying for, such as Internet access and a computer. There's always the free service for those testing the service or financially constrained.

I would like to support Protonmail development with premium subscription. Current plans are however too expensive for basic users.
I would only need basic functionality, with possibility to create email aliases.

Or the other way around, give users possibility to opt out some current features from premium subscription with lesser money.
