Before you buy a Proton Mail account, understand one detail that shapes everything else: your messages are stored encrypted, and the keys to them are tied to the owner's password. So with this kind of mailbox, signing in is only half the job — the other half is not losing access to the mail that builds up inside it. Mailboxes here are listed by marketplace sellers, while the platform watches product quality and warranty compliance; every email shelf is collected in the email accounts section.

Proton Mail lots: auto-registered "Login · Password" versus an aged fresh registration

The "Login · Password" and "Fresh registration" lots are auto-registrations: the mailboxes were registered in advance, and you receive a login and a password. They differ in what the card promises and which cases it accepts for replacement.

"Login · Password": the minimal kit

The Proton mail account · Login · Password lot is described briefly: an auto-registration with login and password included, delivered as a line in the login|Pass| format. Age, registration IP and recovery methods are not stated, so do not count on them. A replacement is due if the password is wrong or the mailbox was blocked before purchase. Once you have signed in, any blocking is no longer a warranty case — and neither is Proton requiring you to link a phone number.

"Fresh registration", "Unused", "Aged 10+ days": how to read these fields

The ProtonMail Account (proton.me) · Fresh registration · Unused · Mix IP (Asia) · Aged 10+ days lot promises more. "Fresh registration" and "Aged 10+ days" do not contradict each other: the mailbox was registered recently but sat for at least 10 days before sale. "Unused" means the addresses are clean and nobody put them to work before you. Aging does not make an address "old", though: it has no sender reputation yet. The domain is stated outright — proton.me.

Mix IP (Asia) and the line format: what changes in practice

Mix IP (Asia) means the registrations went through proxies from a mixed Asian pool. No specific country is promised, and the card does not accept geography expectations within that range as grounds for replacement. Proton's help centre, meanwhile, talks about network reputation rather than countries: sign-ins from networks used for malicious activity get extra checks. So start from a clean, stable address. The line formats differ too: the "Login · Password" lot uses a vertical bar as the separator, the "Fresh registration" lot a colon. If you load mailboxes into software in batches, set the parser to the right separator, or the login and password will run together.

Why the password in Proton unlocks your mail, not just the sign-in

Before you change anything in a purchased mailbox, work out how Proton encryption is built. It decides which actions are safe and which can cost you your entire message history.

Zero-access encryption: what it means for the owner

Proton stores mail with zero-access encryption: in the help centre's words, nobody else can access your emails — not even Proton. Messages between Proton addresses are end-to-end encrypted in transit automatically, while incoming mail from outside senders usually arrives over an encrypted (TLS) connection and is stored already encrypted. The flip side of the same design: if the keys to your mail are lost, support cannot decrypt it for you. Encryption has a boundary too: subject lines and sender and recipient addresses are encrypted, but not end-to-end encrypted. Proton protects the content of your correspondence — it is not a promise of anonymity.

Changing a password and resetting it are different operations

A password change happens in settings (Account and password) and starts with entering your current password. Since the old password is known, the keys stay available and your mail reads as before. A password reset is for people who do not know the password. A code sent to a recovery email or phone gets you back in, but Proton's help centre warns plainly that you may lose access to previously stored emails and contacts. The reason lies in how the keys work: a reset creates new keys for the new password, while the old ones stay encrypted with the old password and are switched to inactive. Messages are not deleted — they become unreadable until something can unlock the old keys.

What brings old emails back after a reset

After a reset via email or SMS, the data can be unlocked in several ways listed in Proton's help centre — every one of them works only if prepared in advance:

Proton advises keeping the recovery phrase somewhere secure but accessible, and not inside Proton services: if you lose access to the account, you will not be able to reach it.

Important: resetting a password via a recovery email does not "fix" the mailbox — it only restores sign-in. With no recovery phrase, no recovery file, no device backup and no old password, the mail from before the reset stays encrypted with keys that nothing can open anymore.

Check first, secure second: the order of work with a purchased mailbox

The card terms set the sequence: a replacement is possible while the mailbox is untouched. The warranty window is short, so right after delivery confirm the mailbox works, and only then make it yours.

A check without changes: what to look at on first sign-in

The check answers one question — does the mailbox work in the state it was handed over. You do not need to change any settings for that:

• sign in to Proton on the web with the details from the line and confirm the password works;
• make sure the account is not blocked and the Inbox opens;
• compare the mailbox address and domain with the card;
• open the Recovery section just to see which recovery methods are already set;
• record your screen from the moment of purchase until the check is over — the card for the "Fresh registration" lot excludes claims without a continuous recording.

If the password fails, the mailbox is blocked, or Proton asks at sign-in for a second-factor code you do not have, contact marketplace support at once without changing anything in the account. If everything went smoothly, the mailbox is accepted, and from then on blocks and checks are on the buyer's side.

Which actions end replacement under the card terms

For the "Fresh registration" lot the card is explicit: any bans and limits after purchase, including password and security changes, are not replaced. For the "Login · Password" lot the line is the first sign-in: blocking after you sign in is not a warranty case. The platform's general principle is the same: it guarantees the account is not blocked at the moment of sale, while what you do with it and any blocks afterwards are the buyer's responsibility. So you set a new password, your own recovery email and a second factor after accepting the mailbox — not before.

Making the mailbox yours: password, recovery, second factor

Once the mailbox is accepted, secure it step by step — everything is done in your Proton account settings:

If you work in an antidetect browser, note that device data backup works only where "Keep me signed in" was ticked at sign-in, and it lives in the browser's web storage: delete the profile and you lose this recovery method too. On devices you do not trust, Proton advises the opposite — leave that box unticked, because a saved session gives full account access to whoever opens the browser after you.

Captcha, SMS and blocks: where they come from and how the warranty treats them

Sudden checks from Proton have clear causes, and the cards state in advance how such cases are handled.

Why Proton asks again: anti-spam and network reputation

Proton explains the "are you human" check at sign-up as a defence against bots and spam: if spammers get Proton addresses easily, other email providers could start blocking messages from its servers. The methods are a captcha, a code sent to another email or an SMS, and the set on offer depends on several factors — for example, it narrows when someone tries to create many accounts. Sign-in protection works separately: if someone ran large-scale malicious activity through the same network as you, Proton temporarily limits sign-ins and tightens checks for everyone on it. On top of that, Proton automatically disables accounts that its algorithms classify as abusive based on behaviour indicators, and it separately reviews reports of bulk and scripted signups; the help centre admits that automated action can produce false positives.

Phone numbers and re-verification under the card terms

For the "Login · Password" lot there is no replacement if the service requires linking a phone number. For the "Fresh registration" lot there is no replacement for any additional checks on Proton's side — SMS, captcha, re-verification. The logic is simple: such prompts depend, among other things, on where and how the mailbox is used after handover, and the seller has no control over that. If Proton asks for a number, the choice is yours — link your own or give up the mailbox — but either way it falls outside the warranty.

Security locks and forced password changes

If Proton's automated systems suspect an account takeover attempt, they can block sign-ins until you verify your identity, require a password change, or both. The verification code goes to the recovery contacts — and if someone else's address is set there, you will not be the one receiving it. Until the password is changed, you cannot read or send mail; after the change, Proton signs out all your other sessions. Under the card terms such a lock after purchase is not a warranty case, which is why your own recovery email should go in as soon as possible after you accept the mailbox.

Ordinary hygiene lowers the odds of checks and protects your access:

• sign in from a clean, stable address; if you use a proxy, take a residential IP and pin it to a specific mailbox;
• keep each mailbox in its own trusted browser profile: its session and device key backup live there, so never open that profile on shared devices;
• if Proton limited sign-in because of the network, its help centre advises moving to a reputable one — your home provider or mobile data;
• do not send bulk mail or pile recipients into BCC — Proton's help centre explicitly advises new addresses against it.

Risk: checks and blocks on Proton's side after purchase are not replaced under the lot terms. Factor that in: keep copies of important messages, and do not build a process on a single fresh mailbox if stopping it would cost more than the mailbox itself.

Proton in daily work: email clients, sending and inactivity

Even a mailbox you have secured does not behave like familiar email — know these differences in advance.

Email clients over IMAP and SMTP: only through Bridge, only on a paid plan

You cannot connect Proton to an email client over IMAP and SMTP directly: the mail is encrypted, and something on your side has to decrypt it. That job belongs to Proton Mail Bridge, a desktop app that runs a local mail server on your computer and encrypts and decrypts messages as they come in and go out. A client such as Thunderbird or Apple Mail connects to Bridge, using a separate Bridge password rather than your account password. The main restriction: Bridge is available only on paid plans that include Proton Mail. The cards say nothing about a subscription, so without paying for a plan, count on the web version and Proton's apps.

How much you can send: plan limits and address reputation

The free Proton plan has hourly and daily sending limits, and every recipient in the To, CC and BCC fields counts as a separate email. On paid plans the limit floats with the account's reputation. For new addresses that have not built a reputation yet, the help centre specifically advises against starting with bulk sending and heavy BCC use. Most importantly, Proton states plainly that the service is not designed for bulk mailing, and that spam violates its terms and makes the account subject to review and possible termination. A Proton mailbox is for correspondence, not campaigns.

Proton can delete an inactive free mailbox

On the free plan an account has to be used from time to time: sign in to any Proton app and do something simple — open an email, for example. If you stay away too long, Proton may delete the account along with all its data. It sends reminders before deletion, but do not build your plans around them. A deleted address generally cannot be recovered or handed to a new account. The exact inactivity period is in Proton's help centre and terms — check it there and put a regular sign-in in your calendar with a margin.

Where Proton fits: backup mail, work correspondence, testing

The card for the "Fresh registration" lot names workflows, backup mail and test environments — a sensible list, given the right expectations.

Backup mail for recovering other accounts

As a recovery address for other services, Proton works well because the messages in it are encrypted and the mailbox itself can be locked down with a second factor. But the backup role has traps. A free mailbox you open only in emergencies risks deletion for inactivity, so scheduled sign-ins are a must. Beyond that, the backup Proton needs its own recovery email and recovery phrase: otherwise a password reset gets you back in but can cost exactly the messages the mailbox was set up for. Also keep in mind that some websites reject Proton addresses at registration — in such cases Proton suggests reporting the site to its support or writing to the service directly.

Work correspondence and test environments

For team correspondence Proton is convenient because messages between Proton addresses are end-to-end encrypted with no setup at all. An outside recipient can get a password-protected email: they receive a notification, open the message with a password you share separately, and the message has a limited lifetime. For test environments — checking a sign-up form, receiving a confirmation email, debugging a notification chain — the "Fresh registration" lot marked "Unused" works best: it carries no one else's history. Just remember that the subject line is not end-to-end encrypted even in encrypted correspondence, so keep anything important out of it.

Where Proton gets in the way, and where to look instead

• bulk mailing and cold campaigns — the service is not designed for them, and spam violates its terms;
• connecting an email client without a paid plan — Bridge is not available on the free plan;
• sign-ups on websites that reject Proton addresses;
• tasks where the mailbox sits unopened for long stretches — a free account risks deletion;
• counting on anonymity — Proton encrypts message content but does not make your correspondence anonymous.

If Proton does not suit the task, the section has other email shelves: Outlook accounts, Yahoo accounts, Mail.ru accounts, Rambler accounts and other email accounts. How the providers differ from one another is easier to compare on the main email accounts page.
