I would be interested in paying $25/YEAR for Unlimited domains and addresses.

I use catch-all and have probably 5 trillion trillion trillion possibilities and am not interested in paying MONEY to use an email ONCE.

I want to be able to RECEIVE AND SEND from ALL domains and all email aliases, unlimited possibilities for each domain, and I have a lot of domains.

PRESENTLY I GET ALL OF THIS 100% FOR FREE WITH GOOGLE APPS and I am unlimited grandfathered in forever. It allows 100 maximum SEND FROM emails, when I use them all I will just remove some I am not using to add more at any time. It allows 5 POP3 emails with 100 "send from" emails.

So I can receive to unlimited number of emails FREE FOREVER with my google apps account which is the #1 most functional email on the internet today.

My google apps account has 15GB of storage for free, but I never used this much. In fact over 10 years I only used 8GB. You should allow UNLIMITED everything except for storage. I can see having to pay more for high storage, but the rest is just SOFTWARE, there is zero expense to you so I should not have to pay for what costs you nothing.

Summary WHAT I HAVE NOW:
Google apps:
* Cost: FREE - grandfathered forever.
* UNLIMITED domains (INFINITE to receive mail to same inbox.)
* 100 "send mail as" accounts at one time (can delete and add whenever I want)
* 5 POP3 accounts (would like more, but at least this many)
* 15GB storage
REQUIRED FEATURES THAT IS HAS ALREADY IN MY FREE GOOGLE APPS ACCOUNT:
* dark theme
* delayed send feature (under "labs")
* every send mail as can have its own html-based signature
* robust filters
* best search filter
* best folders/archive capabilities
* canned responses

The only reason to leave gmail is because I want more privacy. But I do NOT want it for hundreds of dollars per year, it's just not worth it especially when I already have this for free. But I would pay TWENTY FIVE dollars per YEAR for the same or better benefits as google apps, just for the benefit of privacy.

I will never use Protonmail despite having a protonmail account from the very beginning, until I can use it as an affordable replacement to google apps. FOR YOUR CURRENT ABSURD MONTHLY RATE I COULD INVEST THAT INTO SOMETHING ELSE AND IT STILL ISN'T EVEN CLOSE TO UNLIMITED FOR MY USAGE EVEN THOUGH I HAVE VERY SMALL STORAGE USAGE, SO IT'S PRESENTLY A TOTAL WASTE AND USELESS.

You could probably have 1 million new users overnight if you offered a google apps replacement for $25 per year with the same features as I showed above.

I would have already paid for the last 2-3 years if you had this option.
I would never use it when i have to pay for individual addresses, especially since I already have it all for free in Google Apps.

Everyone is looking to leave google, and yours would be the best google replacement except for your PROHIBITIVE COST, AND PRICING STRUCTURE.ore restless and want to leave google. BUT NOT FOR HUNDREDS PER YEAR. $40 per YEAR would be the MAX per year for UNLIMITED everything, although even at $40 I would be reluctant to pay that and may still not sign up because of this high cost per year of $40. But for $25 per year I would jump immediately for this unlimited plan.

As a protonmail+ user using a custom domain I shouldn't have to use a filter to have my custom domain emails show up in my main inbox. I would suggest having multiple inboxes under 1 account. What I mean is you sign in with your email and you have an inbox for name@protonmail.com, another mailbox for a@domain.tld, and another for b@domain.tld . Under each of these inboxes they can all have their own spam and archive folders and whatnot. This would be much nicer, but for some users as well who prefer a unified inbox protonmail could automatically color code the mail so it is apparent which address it was sent to. This is my biggest gripe with protonmail at the moment, but if this is implemented it would be amazing.

Use Pushy instead of GCM (for one example). It is a replacement for GCM but each app developer must manually embed Pushy in their apps. Pushy cannot itself be flashed onto a non-GMS phone to replace GCM.

Protonmail app development should support devices without GMS, you can embed the Pushy SDK in your app and it will work on these devices, instead of using GCM.

I think there is a growing market for people who do not want to use Google services at all. This one change would also be innocuous to those with Google services installed while giving "unGoogled" phones the ability to receive push notifications.

Even selling this app (downloadable from the Protonmail website) would be reasonable to help fund or pay for pushy fees of $.005 per device per month (unlimited puush notifications). However Protonmail could even host their own Pushy service which may be more feasible for cost and security stand point.

I value the addition of dual factor authentication, but I find it frustrating that I have to open an app on my phone and quickly type in the relevant 6 digits before the code refreshes.

I have many such MFA apps on my phone, and my favourite by far is Microsoft Authenticator and LastPass Authenticator. The reason for this is that when I log in to ProtonMail, a push notification is sent to my phone and I simply have to press yes or no on the notification to allow or deny the login.

This is a massive time saver and I don't believe it is any less secure, because the phone has to be unlocked before the command can be given. Using fingerprint authentication, this takes a matter of seconds,

Please consider looking into this enhancement,
