Proton is amazing
Needs ability to select mails
When reviewing your emails, you can’t select multiple down the list for deletion or whatever it may be. You need to delete one by one, which is annoying. I disconnected my old gmail from proton because I can’t bulk delete.
Also when you get links in the email, the app sometimes breaks them. I got a verify link from my bank, and when clicking from the proton app, i got a 404, but from proton in my browser, it worked fine.
Fix your app! Add checkboxes down the inbox so people can bulk select. I prefer proton to gmail but it’s got a ways to go.
Getting worse by the day
Thanks. JL
Horrible
Error
Edit: Ok no problem… many thanks for the reply.
Thank You!
08/2026 on Original Review: Hello! Great App for the most part but... on both iPad and iPhone... Email takes a while to load. Trash doesn't always delete. Thank you!
My personal mail
Hopeful about this one
My only complaints about this app are: the interface is kinda goofy and the app loads slowly. I'm sure it'll improve as Proton continues developing it.
As far as the interface goes, the unfiltered inbox is visually busy and there doesn't seem to be a way to make "Unread" the default view. Any other issues will be iOS-wide, so nothing Proton could do about them.
problems with login
Thank you for your hard work
Unable to log in
Terrible Company
Fix it.
Not liking the app. Fluffy and not up to today’s standard
This app is really not intuitive or easy to follow or even use effectively compared to Apple Mail or Google Mail app etc.
Really not impressed by the app or proton interfaces.
