Proton free email is pretty solid.

Proton free email is pretty solid.
I use their competitors paid. Tu**.

If you are degoogling Proton will feel intuitive and similar. It appears as if they are trying to be the alternative, by also offering other services.

I have had no problems using the free service.

They are a, want all your eggs in one basket company.
The paid service I have at their competitors is run poorly compared to Proton whom answers emails, even from a free account quickly. They competition doesn't offer any support to free.

They lose a star as the format why familiar is crowded.
I mean it looks good but its not well designed.
When you look at Google Gmail and their services which many come from to Proton, and if Proton is trying to be the next Degoogle source the layout needs improving. Just seems cluttered and messy.

That article is being misinterpreted. Proton didn't hand information to the FBI. Swiss authorities processed a legal request tied to a serious criminal case, and only optional payment info was disclosed, no emails, messages, or account content. This actually proves how little data we hold. For maximum anonymity, we accept cash and crypto.

Eine tolle Alternative zu Gmail!

Eine tolle Alternative zu Gmail, Apple Mail und anderen Anbietern.

Proton bietet mit seinen Produkten eine gute Rundumlösung zu Google an. Ich war vorher bei einem anderen privacy-freundlichen Anbieter, wollte aber eine geschmeidigere Lösung, die besser aufeinander abgestimmt ist. Proton hat mich seither nicht enttäuscht.

Mit dem Proton Unlimited Tarif hat man alle wesentlichen Produkte der Proton AG. Wenn man auch alle nutzt (z. B. Mail, Drive, Pass und VPN), ist es kostentechnisch direkt lukrativ, statt alles einzeln zu buchen oder verschiedene Anbieter zu nutzen.

Habe die bezahlte Vollversion um von MS und Google weg zu kommen. Im ersten Schritt habe ich MS OneDrive durch Proton Drive ersetzt. Natürlich muss man sich erst einmal etwas einarbeiten und ausprobieren. Letztlich hat die Installation auf den Endgeräten (Notebook, Laptop und Smartphone) sehr gut geklappt. Funktioniert seit zwei Wochen sehr gut und zur vollen Zufriedenheit. Im Moment experimentiere ich mit der Mail Funktion. Die ersten Tests machen mich auch glücklich. Als Privatnutzer der von MS365 und Google weg will bin ich sehr zufrieden.

Terrible user interface, one of the worst

Terrible user interface and I'm a software designer. I signed up with Protonmail in 2014 and found the UI acceptable and easy to follow. I liked how the buttons were labelled as text, so there was no mistaking them.

Progressively they've turned it into one of the worst UIs around. Take two simple examples :

I add a series of attachments to send with my e-mail and when I look closely, it has rearranged them in reverse of the order in which I've added them. I don't want this because I intend for the recipient to see the most relevant attachment first.

I then click the bin icon right next to the attachments, to delete the attachments and try again, but no, the bin attachment deleted my entire e-mail draft, even though it was adjacent to the files. I have to start again.

I add the attachments in reverse order, thinking I'm being smart and then send the e-mail. When I check it afterwards, I find that it actually sent them in the sequence I added them, but showed me a different sequence while composing the message. It turns out that it sorts the attachment file names alphanumerically, yet sends them chronologically. This is par for the course with Protonmail now — the UI is illogical and poorly planned. All the historic concepts and principles which we came to recognise with leading desktop-application-email programmes and found reasonable design choices — such as showing attachment files in the sequence in which they will be sent — are ignored with Proton.

The worst thing for me is the mistakes I make easily, because the buttons are just icons and not text. I don't want to waste my time hovering over every icon before clicking it. On top of this, support from Protonmail has often been a drain on my time — for small observances and bugs, support staff frequently disputed the bug and asked me to spend time creating videos of the problem. It is clear that many of the support staff have a very incomplete understanding of their own technology and can't even be bothered to verify the customer's simple example steps. Don’t waste your time with Protonmail, just use conventional e-mail applications and popular encryption standards and manage it yourself.

Thanks for taking the time to write such a detailed review, especially from a design perspective on how attachment handling, icon-based controls, and draft behavior can impact workflow, and feedback like this is valuable.

If you’ve reported these specific issues to support, please share your ticket number so we can review how they were handled. If not, we encourage you to open a ticket at https://proton.me/support/contact
so the team can properly investigate the attachment ordering and draft deletion behavior you described.

Absolutely useless. Password reset refuses to work!

Absolutely useless. Do not use this scam.

Used it for several months until suddenly it randomly signed me out. Now my login isn't working and password reset simply DOES NOT WORK!!!!! Its 2026 and these chimps STILL haven't implemented a simple password reset protocol.

I get two options;
Enter your recovery phrase. What on earth is this? You never told me to set one up? What sort of weird company introduces something like this but doesn't let the user actually set their own phrase? Madness. I've had hundreds accounts with all sorts of websites and I've never once been asked to "enter a phrase" as a way to reset my password.

The second option is to enter my recovery email address. I only have one other email address so I entered that and it's not recognising it.

Absolutely useless, amateur operation. Why there is no phone verification nor any other way to recover a password, such as a simple 6 digit pin etc.

Do not trust this company. Absolutely useless.

Thanks for sharing your experience. Proton uses zero-access encryption, which means account recovery works differently from most services. A recovery phrase or recovery email must be set up in advance to reset access. If neither was configured correctly, recovery options can be limited for security reasons.

Please contact us at https://proton.me/support/contact
and include any details available so we can look into your case.

Paid long time account disabled for unstated reason. Very frustrating dealing with automatic responses to try to “reinstate”.
Consumer account, paid, email & vpn.

Absolutely do not use the proton email app as it has locked all saved email data.

Terrible customer service regarding this issue.

Die App downloaden gut/Anmelden katastrophal

Die App downloaden, kein Problem.
Sich dann aber anmelden ist eine negative Erfahrung.
Fast keine Wunschadresse mehr vorhanden. Dann etwas gefunden.
Aber dann kommt die Stelle die mich zum verzweifeln bringt.
Mailadresse oder Tel. Nummer angeben um bei Verlust des Z.B. Passwort, User, etc. Nicht ohne Zugang dazustehen, soll man eine Alternative eMail Adresse oder eine Handy Nummer angeben.
Aber das System sagt, keine Chance, Mail-Adresse funktioniert nicht, Handynummer funktioniert nicht.
Gut, überspringen... Aber ich erhalte kein Zugang, ich erhalte kein Code bzgl.Bestätigung, etc.
Wa bitte schön ist das? Und dann soll man auch noch zahlen.
Nee, so nicht

Thanks for the review. During sign-up, certain usernames may already be taken, and additional verification steps can be triggered to prevent abuse. If a recovery email or phone number isn’t accepted, it’s usually due to system validation checks.

If you’re not receiving a confirmation code, please contact us at https://proton.me/support/contact
so we can review what’s happening with your registration attempt.

Extremely insecure

Absolutely shocking service. It is supposed to be secure. I have had my account accessed, my password, recovery phrase and recovery email address CHANGED to an address is not mine, and all I ever receive back is one generic response after another advising me to take steps I CANNOT take and have email I need to access for a court case. Shocking. This has to be the least secure AND the least recoverable email address. It fails on BOTH counts

I moved to a paid "unlimited" account…

I moved to a paid "unlimited" account for greater security and as a paid user I am disappointed to date. I had issues with 2FA and when I reached out to a Customer representatives they take 2/3 days to respond. They suggested the synching of my computer/phone could be at fault (not that you can change the the clocks on them) as I was using the Proton authenticator app, yet the delay in changing time was 4 seconds between them. No solution offered. Using the Pass function on my computer asks me to re-set my preferred theme every morning I log in. You don't expect these issues when using a paid service. After taking 2/3 days to respond, they then send an automated message after 48hrs to see that they have answered your query! Really poor PR. No personal response and they chase you for a response after taking 2/3 days to respond. To cap it all, I received an email from Proton saying I could earn up to $1,000 by referring other users ($20 a referral). What an insult. Save the referral money and hire more computer engineers to resolve the glitches in your software! A good service will sell itself, you don't have to pay users for additional customers. Sort your issues out before I refer anyone.
To be balanced, the basic email service works well but you would expect all aspects of a service to work well for a paid service. #4328062

50€ all'anno per fare il vostro…

50€ all'anno per fare il vostro venditore? No grazie.
"Esperienza imbarazzante. Pago 50€ l'anno e devo beccarmi un diamante per l'upgrade sulla dashboard ogni volta che apro l'app: un comportamento da app 'freemium' scadente, non da servizio professionale. La cosa più grave è la gestione delle mail criptate: le usate come spot pubblicitario obbligando i miei destinatari ad aprirle sul vostro sito. Questo mina la percezione di sicurezza e serve solo a portarvi traffico. Mi avvarrò del rimborso entro i 30 giorni: la privacy non si paga per poi essere usati come mezzo di marketing.
Dicono che non richiedono un account a chi riceve le mail con password, ma mettono in grande mostra inloro
loghi e ci sono "create a free account " ovunque, uno che paga non vuole essere sfruttato da Proton per farsi nuovi utenti, e rivelare il provider che un professionista usa , sono stati veloci a rispondere qui, ma al modulo e mail di rimborso ancora non rispondono, ho richiestk rimborso dopo 30 ore dal pagamento, aspetto 48 ore prima di iniziare a tutelarmi!
Aggiornamenti: hanno provveduto ad avviare la procedura di rimborso sul metodo di pagamento iniziale, ma comunque la perdita di tempo non verrà ricompensata !!

Thanks for your feedback. Paid plans do not include ads, and upgrade prompts are informational.

Emails sent to non-Proton users do not require them to create a Proton account. They receive them normally in their inbox. Only if you choose to send a password-protected encrypted message will it open in a secure web view.

If you’re considering a refund within the guarantee period, please contact us at https://proton.me/support/contact
so we can assist you directly.

Good service

I’ve been using Proton Mail for about 8 years as a paying user, and I’m really very satisfied. The only issue is that after the latest Android update, it sometimes doesn’t send email notifications, but I’m sure they’ll fix it soon.

In love with Proton Bundle!

I decided to try Proton bundle starting with paid Unlimited bundle plan. I have not yet tried the Drive, but I am in love with Proton Mail, Proton Pass and Proton Authenticator. After a few days I upgraded to Duo bundle to increase the storage and for extra email addresses, even though I am the only user. GUI and choice of themes is amazing. No steep learning curve. I got used to it so fast! I rarely leave reviews, only when I am indeed in love with the service or a product, and this is the case here. The only downside in Proton Mail I can think of is that you can only delete 1 email address per year. I created a couple that I decided I did not need and could not delete them, since I had deleted one prior to that. I know where this rule is coming from, but if Proton could identify that some specific email address was never used to send or receive email it should not be a subject to that rule. But it is not a deal breaker for me. Still love everything about Proton and super happy that I switched.

Leider nicht zufrieden (Rückerstattung nicht möglich).

Leider nicht zufrieden.
Habe sowohl den ProtonPass, als auch den VPN Dienst jeweils einzeln gekauft, da Features die ich brauchte nur darin enthalten waren.
Leider haben beide nicht funktioniert und das zurückerstatten war nur bei einem der beiden Dienste möglich. Das ist ziemlich enttäuschend. Dann gebt den Nutzern die Möglichkeit erst die Dienste z.B. 7 oder 3 Tage zu testen.
Der Support war trotzdem sehr freundlich, nur ist das leider nicht hilfreich.
