Free Encrypted Email Without a Phone Number (2026)

If you want free encrypted email without phone number verification, you have two serious options in 2026: Tuta and Proton Mail. Tuta is the pick when the entire point is that no phone number ever enters the picture — signup asks for a username and a password, nothing else, and the free tier starts at 1 GB. Proton Mail is the runner-up: its free plan is polished and grows better over time, but its signup verification is risk-based, and under some conditions it will push you toward SMS. There is no budget pick here because both cost nothing; the upgrade-path pick is Proton if you expect to want aliases and a custom domain later.

Why “no phone number” is a reasonable requirement

A phone number is the most durable identifier most people hand out. In much of the world it is tied to a carrier account with your name and billing address on it, it rarely changes, and it shows up in breach dump after breach dump, where it works as a join key linking your accounts across services. Data brokers use it the same way, and the same machinery that puts an email address on a broker list will put a phone number there beside it. None of this requires a nation-state adversary — it is ordinary ad-tech plumbing plus the steady drip of breaches. The same pipeline is what puts your address on the lists described in why your email ends up on data broker lists.

So the threat model here is modest and realistic: you want an inbox that a data broker, a breach dataset, or a determined ex with your other account details cannot trivially connect back to your SIM card and, through it, to you. That is a different goal from hiding email content, and a provider can satisfy one without the other. If you have not settled that first question, do you actually need encrypted email is the place to start. The two picks below satisfy both.

The winner: Tuta

Tuta (formerly Tutanota, based in Germany) states it plainly: it is one of the few providers that lets you create an email address without a phone number, for free, with no personal information collected at registration. Everything in the mailbox — message bodies, attachments, and notably subject lines — is end-to-end encrypted, and the company has been rolling out quantum-safe algorithms on top of its existing scheme. Tuta also says it does not log IP addresses and blocks remote images by default to prevent tracking pixels from firing.

Per Privacy Guides, free Tuta accounts start with 1 GB of storage, and if you later upgrade, you can pay via cryptocurrency gift cards through ProxyStore, keeping the payment unlinkable too.

One operational note from Tuta’s own documentation: new free accounts are sometimes flagged for manual approval to deter spammers, typically when the signup arrives over Tor or a VPN, and approval can take up to 48 hours. That is a delay, not a demand for identity — you still never provide a phone number.

The runner-up: Proton Mail

Proton Mail’s free plan gives you one encrypted address. Proton’s official plan documentation puts Proton Free at 1 GB of Mail storage plus 5 GB of Drive storage, with no custom domain support. Mail is encrypted with a PGP-based scheme, and Securitum provided a security attestation letter for Proton in November 2021, as noted by Privacy Guides.

The phone-number question is where you need to read the fine print. Proton’s human-verification page lists three possible checks at signup: a CAPTCHA, a code sent to another email address, or a code sent by SMS. Most signups only see the CAPTCHA. But Proton says users who create multiple accounts or arrive over Tor may only be offered the email or SMS options. Proton also states — this is a vendor claim, not independently verified — that it stores only a cryptographic hash of any phone number or email used for verification, not the value itself, to detect reuse without keeping your contact details.

Practical workaround: if Proton asks for more than a CAPTCHA, choose the email option and supply a throwaway address rather than a phone number. If only SMS is offered, changing networks (off VPN, different connection) and retrying usually restores the gentler options; failing that, Tuta is the answer.

Threat models served

1. Inbox must never touch your SIM identity. Winner: Tuta. No phone field exists at signup, and the worst case is a 48-hour approval wait.
2. Everyday private email that grows with you. Winner: Proton Mail. The free tier is small, but the paid path adds 15 GB, ten addresses, and a custom domain when you outgrow it.
3. Even a future paid upgrade must stay unlinkable. Tie. Privacy Guides notes Proton accepts cash by mail, Bitcoin, and Monero via ProxyStore; Tuta takes cryptocurrency gift cards through the same shop.

Pricing, as of August 2026

Both free tiers are genuinely free: no card on file, no trial clock, no expiry. Proton Free is 1 GB of Mail storage plus 5 GB of Drive with one address; Tuta Free is 1 GB with one address and no aliases. Neither free tier supports a custom domain.

If you later decide to pay, these are the entry tiers, taken from each provider’s own documentation. Both bill in euros from Europe, so the amount charged in another currency depends on the exchange rate at checkout.

	Tuta Revolutionary	Proton Mail Plus
Price, billed annually	€3.00/month	€47.88/year, which is €3.99/month
Price, billed monthly	Higher than the annual rate	€4.99/month
Storage	20 GB	15 GB, shared with Proton Drive
Aliases	15, plus unlimited on your custom domains	Up to 10 addresses
Custom domains	3	1

Two details are worth pulling out. Tuta’s paid tiers do not count custom-domain addresses against the alias limit and include catch-all, which makes Revolutionary the cheapest credible route to encrypted mail on your own domain. Proton’s Mail Plus is the cheaper entry into a stack — Unlimited and above bundle VPN, Drive, Pass and SimpleLogin aliases — so the comparison depends entirely on whether you want a mailbox or an ecosystem. The full head-to-head works through the rest of that trade-off, including the subject-line and PGP interoperability differences that matter more than price for some threat models.

Paying without breaking the unlinkability you set up at signup is its own problem. Per Privacy Guides, Proton accepts cash by mail, Bitcoin and Monero through ProxyStore, and Tuta accepts cryptocurrency gift cards through the same shop. A card payment re-links the account to your legal identity as effectively as a phone number would, so if the whole point was an unlinkable inbox, plan the payment method before you need it.

The catch

Every product has one. Proton’s is that the no-phone experience is conditional: its own support page reserves the right to narrow your verification choices to email or SMS based on signup signals, which is exactly when a privacy-conscious person on a VPN is most likely to be signing up. Tuta’s is interoperability: it does not use OpenPGP, per Privacy Guides, so you cannot exchange encrypted mail with PGP users outside Tuta — encrypted conversations with non-Tuta contacts happen through a shared-password link instead — and you are committed to Tuta’s own apps and web client.

And a catch shared by every encrypted provider: end-to-end encryption protects content, not the fact of communication. As the EFF’s Surveillance Self-Defense guide puts it, metadata — who you write to and when — stays visible to the provider and can be revealing on its own. What email metadata leaks itemises exactly which fields survive end-to-end encryption. A no-phone signup shrinks what that metadata links back to; it does not make you invisible, and no honest provider claims otherwise.

Verify it worked

After signup, confirm you got what you came for. Check your account settings and confirm no recovery phone is set (on Proton, skip the recovery-method prompt or use a throwaway email; a recovery phone quietly re-links the account to your SIM). Send a test message between your new address and an old one, and note what the receiving side sees in the headers. And before reusing the address anywhere, decide what it is for — an inbox stays unlinkable only as long as you don’t sign it up for accounts that already know your real identity.
